I don't care about marginal gains on my bike because I don't race, but I love watching your videos and learning all the theory.
This
@@peterknight7880 that's it, I simply don't care about performance, but I think this info super interesting
Yeah, but now that I'm learning all these tips at the gravel speed shop, I'm thinking maybe I'll win a few more trophies for roosting in the over-60 class. 😀
exactly
read my mind.
I thought this was only going to be a boring advert for Factor but I am glad that this video is much more technical.
Aero is less complaint.
@@mattk8810 you literally have wider tires tho?
thanks for the simple math brake down. especially at 10mph! Ive never an aero breakdown this slow, and it's definitely a real speed for a lot of people
You almost could have been doing a video about time trialing. Everything you mentioned really matters. Good stuff.
I liked this a lot because it brought together a lot the things you talk about into one video showing practical applications.
Backward hat Dylan was on point this video! Love the nerdery.
Great content as always Dylan! 🤩🙌
Your video convinced me to only ride in the drops all the time, even on my mountain bike.
Very Good content here D. One of the best I’ve seen of yours especially with Backwards Hat D.
I subscribe to a lot of channels, but yours are the videos that I save for reference. This video is no exception. Well done.
Your videos take a while to come compared to others but they are well worth the wait. Thanks for sharing and putting out all the science and experience to back it. I'm not a racer but I'm always seeking to improve so your channel is well loved on my part. BTW, your alter ego character is genius, top notch comedy and I always look forward to it. Thanks again!
Good stuff Dylan. I am the proud owner of regular Ostro and love everything about that bike. Still waiting for your review of the Lando XC.
Best video my man. I appreciate these informational videos
Thanks for sharing your setup!
This is good stuff! This chanel should be much bigger!
Great video as always
I don't ride gravel, but still found this interesting and educational. Thank you! Besides that, I had missed Backwards Hat Dylan.
Pleasure to meet you. Good luck at the big sugar race!
Matters alot for Dylan since he lets the first group go after 23 mins. Top 5 fav channels. Even if its a topic I don't care about I'll let it play and like for support.
Lots of good takeaways, even for more casual or fondo riders: keep your chain clean, tidy your cables, choose tires carefully, etc.. These will let riders at all speeds use less energy and ride faster or further. Keep up the solid content!
I'm glad I found this channel because my first race is this upcoming Sunday (Gravel)
Kudos to Factor. So much cool and right things done. Rest assured you are not the only one preaching to the industry to do the simple and obvious things like that handlebar where you can screw aerobars on and off to your liking. Actually it blows my mind how intricate and overengineered (cough, Canyon, cough - but they aren't the only offenders) some integrated cockpits are and how the companies wax lyric on a few saved watts here and there when the greatest saving is the riders position. Aerodynamics and comfort for long gravel rides... If you want that you have that to throw that cool integrated cockpit out of the window with many top gravel (and road bikes for that matter) bikes and mounting a normal stem handlebar combo to be able to fit real aerobars. And you have a PITA of a rerouting / reconnecting brake hoses to boot.
So again - hat's off to Factor. That's how it's done.
Gravel has had me scratching my head for a long long time. It's a race? It's a scene? Its' how you go ride alone in the woods with no cars? What are those bikes?? They're road bikes... mostly, until they're mountain bikes... wait... I finally got one and for me it is the ability to ride just about anywhere, any surface, and all on the same bike, on the same ride. It's awesome.
love the direct mount aero bars. the only other company I could find doing that is Vison. The METRON 4D FLAT M.A.S. AEROBAR. Not only does it look cleaner but as someone who rides with clip on aero bars it would be much easier/faster to take them on and off without the hassle of leveling them correctly each time.
I got the 4d MAS for my road bike last winter, and they are fantastic. It takes me 5 minutes to install the aero bars (less to remove them), and thus do it often depending on the route/training I am doing. I wish this was more popular and available for all integrated handlebars. I hope factor adds this one to their road lineup too!
@@dmallo nice! I have been debating on buying them for my road bike
ENVE have optional extensions for their aero road bar. Which is of limited availability lately
Great video as always. I just shared it to my Facebook page.
Great Vid Dylan, I always enjoy them with the comedy inserts. Yeah your right on all the points you make. I own a Diverge which only has tiagara parts and it still weights the same as all the pro models. I have fun with my bike and do gravel close by me. It was hard finding ng the sweet spot for n my tire pressure for my pathfinder so 38. I finally settled on 35 front n 37 on back tire on size 38’s.
awesome summary, I switched to an aero gravel bike this year (3T Exploro Racemax) !00% agree with everything you said!
Possibly your best video yet
Dylan, maybe a summury about your preparations to the season (zone 2, HIT and weight/gym trainging and so on..) and a conclusion what did work for you what did not and what would you change for the upcomming 2023🙏🙌🏻
btw thanks for awesome content/knowledge❗️
Great video. I love it that you speak your mind and use the equipment that makes the most sense.
A question - Your seat is slammed all the way forward. I wondered what your saddle seat back is?
Appreciate the insights
Also, this bike looks damn cool! It might not make you faster but it makes you look better. Worth it. :)
Great video once again. Great learning 4 me. Thx.
Hi Dylan! Absolutely love your content. I learned a lot from it, and it's safe to say all the provided knowledge has increased my performance and fun on the bike. However, what really caught my attention in this video was that you run bigger chainrings in the front. I already upgraded my bigger chainring from 46 to 48 (GRX) about 10k ago and really felt the difference. Since my next drivetrain maintenance is fast approaching, I already had a look into the compatibility of the GRX groupset with a Shimano road crankset. Unfortunately it seems there is next to no information available, apart from GRX (47mm) and road groupsets (43/44mm) having different chainlines. Would appreciate a lot if you leave a short comment about how you went about installing bigger chainrings. Best regards from the flatlands of Northern Germany
I don't care about speed, but I do care about efficiency. Riding further in the same amount of time means I see more and have more fun ;-) Especially when efficiency "hacks" are free (or cheap).
Oh you arrive at your destination 20 sec faster over that 4-hour ride lol It's marketing hype that would not even benefit the pros when you consider most of the they are drafting aero gains are important to time trial and that's about it the rest is more and more marketing blurb.
I watch all your videos. After 34 years of cycling there’s still more to learn. Many thanks and… where/how can I buy a Factor bike?
Progress is sublime. 😎
it just looks so good
Factor bikes for the win. Nice set up Dylan.
Chamois is a softened deerskin. My wool cycling shorts had a deerskin chamois.
I got a Ventum GS1 this year. Seems to be the best value in Aero Gravel by a wide margin.
Thanks for the "Performance Shamimg"!!!! 🚲🚲🚲🚲🚲🚲
I guess this means we are going to start getting aero mountainbikes. Can't wait.😁
Agree with your wider tyre theory - I have both 40 and 45 mm Pirelli Mud tyres on my gravel bike and the wider ones are faster and, of course, more comfortable.
It's kinda funny that somebody that loves riding a 40 lbs drop-bar Pugsley on gravel races would be interested in aero gains (see profile pic from The Almanzo years ago) ... but you really made the point, getting aero is important. Being one of the only people racing gravel with drop-bars on a fatbike, I'm regularly on the the podium for fatbike categories, and frequently beat riders on new CF gravel bikes to the finish.
enjoyed very much, thanks.
1:45 This was a very surprising result to me. Good stuff!
Aero Gravel - The Future is now, old man! :) Great video! What's the size of these pirelli tires?
Super interesting suff! I would absolutely love to hear your thoughts in a future vid on Jonas Vingegaard's bike having a 1x drivetrain, both last year and this year.
Yes great video, I do get a lil board of the white paper. I’ll just take you at your word 😄. I don’t care much for gravel, but now I feel like I need to care more about it on my road bike!
Watch that seatpost wedge. Hearing a lot of people slightly reshaping it for more surface contact with seatpost.
Love your videos! Keep it up!
I see body position as being a major improvement in aerodynamics, but hoods, cables, etc., I see being in the realm of the "aero-weanie". (close cousin to the "weight-weanie")
Yeah, I’m trying to find a way to fit my Stache wheels and tires onto my Tarmac, should be lightning fast :)
"Aerodynamics makes some sort of small difference at all speeds, even very slow ones"
/proceeds to show a clip of Dylan motoring along comfortably at a pace I could handle for 73 whole seconds before giving up biking/
I love that it’s possible to have aero bars on those handlebars, they would be even better if they would allow separate adjustments of width and reach
Changing flavors on the Hyper Gain Beast Mode Mass Gainer Raw Edition enabled me to sit up on the bike during 100 mile races and come in 2 mph faster than the full aero race position.
if i was a bike company i'd only make 2 dropbar disc bikes:
one would be aero, racing optimized with clearance for ~40mm (as measured, not the conservative estimate)
one would be endurance with clearance for 45mm and more
i think those two would fit 99% of riders
I’m always here for more gcn bashing
Above all 4 things you mentioned is positioning. You can do quite a bit just by optimizing your bike size & fit. It's also better to have a slightly less aero position that you can hold for 4 hours straight, rather than having a super aero position in the drops that you can only hold for 5 minutes, and then you end up riding with straight arms on the hoods all race.
That's funny where I had the same thought pedaling in the mid range of a cassette is more efficient . The only difference I went to a smaller front single chainring to match up to my 12 speed pie plate in the rear as I ride more technical MTB trails and mostly not getting those higher speeds . The smaller ring keeps me in that mid range for a majority of the ride . I do think 2 by systems with smaller cassettes are more efficient than the single rings and the pie plates on the rear
I converted from a 1X setup to a 2X setup. I mostly ride paved roads, dirt roads, and gravle so i have no need for a 1X's chain drop resistance anyway.
Hi Dylan, thanks for your videos, I would like to know more about how to train the Vo2 by bike and how to incorporate it into the training plan together with the FTP sessions.
I raced on Continental RaceKing Protects in 27.5x2.2 for Unbound XL, Rockstar 250, and Gravel Worlds 300. Everyone was so shocked, but I was at the front end of all of those races and was happy
Cool this is what I was thinking about too but saw it wasn’t as common setup, is it?
Have to say, you’ve come a long ways from your original clip on tri bars bought from Amazon.
I don't care that much either but it is helpful when I make decisions on the new Giant Revolt purchase regarding wheel and tire choices. I ride on pavement and light gravel. Retiring in 2 years and rides will increase.
Another very informative video. Any idea when the bars will be available? I don't see anything on Black Inc's website.
Cool video! And cool bike! That saddle looks really far forward tough. Do you not get a bit sore hands because of this?
Only a couple of mins in but one of the other considerations is you are more likely to be in the wind/not in a peloton in a gravel race. So despite a lower speed the effective wind speed is higher
1. why drops better than hoods? tests (even implied in your vids) show low forearm frontal area (hoods) faster than drops 2. wider tyre rolling resistance: N=1 experience (on an interval - 100s of repeats on the downhill); it's the profile that matters - GK knobbly significantly slower at higher speeds (downhill) than visibly more aero Pathfinder Pros at same size
I'm glad Factor makes this bike, because there is no reason a gravel bike shouldn't be aero, and there's little reason an aero bike can't have clearance for wide tires. There's no reason you should need to buy three or four bikes!
In the last video within this video you're not wearing an aero helmet ???
Does that change when you race? How about raceway gear? Speedsuit?
Is there a video coming ?
Cheers, love your content!
On a recent "The Gravel Ride" podcast Josh P. Claimed that just aero drop bars can save up to 28-30 watts at wind tunnel speeds. I believe if I'm correct that speed is usually 30mph. While I normally travel at half that speed, I am now shopping for an aero drop bar. And my rationale is actually less about the watts I might save (I'm on a steel non-aero frame with exposed cable), and more about the comfort of the wing shaped bar tops. Interesting stuff here. Nice video Dylan!
they are so comfortable man
Yeah, I kind of wish that those were a possibility in alloy, and NOT exclusively carbon, but eventually I might get them anyway in the crunchy stuff to try and alleviate my 'cyclist's palsy' (and yeah, they look cool as well!).
Josh also claimed that the 'nest' of cables coming out of the bars in the middle, under the stem (like I currently have on my now very 'old school' frame and setup), is decidedly and measurably UN-aero, and DOES actually cost cdA watts, just like Dylan explained above.
So, sadly, whatever infinitesimal 'gains' I might get from the NACA shaped bar tops will be negated by those exposed cables.
@@LS1conehead since I do not run electronic shifting, I to have cables that will cause aerodynamic disadvantage. Honestly, The main reason I would get a flat top arrow style handlebar is for the possible comfort factor. It does make a lot of sense that a wide flat top will be more comfortable in your palms.
To better answer the question of WHY the aerodynamics give you a better advantage at relatively lower speeds, we could observe a basic air drag model and see that air drag is directly prepositional to the drag coefficient ( aerodynamic efficient), but is proportional to the SQUARE of velocity. So overall velocity will always have a greater impact on how much resistive force is experienced and as Dylan pointed out, compounded over time that will result in greater time gains at lower speeds.
factor needs to update (steepen) their seat tubes angle!
3T exploro has been out for some years, probably the first aero gravel
Sick bike ,
Great vid. I'm wondering though, regarding the additional drag the cables create under the handles bars..................isn't that a moot point since the number plate is usually right in front of them? And, what amount of drag does the number plate create?!
You should get a regular aero bike and slap on gravel tires and gearsets onto it.
Madone, aeron, supersix, venge vias, felt ar are the fastest frames with the lowest watts.
I care about marginal gains because going slightly faster makes the suffering slightly shorter. Ive got the *other* aero gravel bike from 3t and it forced me to sell my endurance road bike because it was slower and less comfortable.
I don't like Aero Bars. Use Specialized S Work for a few years took it off and pun on FSA-Force Light Nano and love it because of the easier adjustability. For me on the hood and the drop make only 2kmh difference. For long ride and races comfort is very important for me rather than fighting with my bike I rather choose comfort.
I see you have GRX with SRAM crank arms/power meter. I have read that the SRAM width is slightly diff from GRX. Have you noticed any alignment issues? Maybe my internet source was wrong.
I have GRX 810 with Garmin power pedals. I have not been impressed with the garmin pedals and I need shorter crank arms. Thinking about doing the mixed set up that you have. I have a mixed setup on my road bike and it works great.
I like the aero gravel bike option, since IF I ever can afford to buy a new, crunchy carbon, disc braked, fully hidden/'integrated' cable/brake lines wonder, I can buy ONE bike to ride on both the roads AND the canal tow paths around here (with just a wheel/tire change, of course).
I do not like the 'MTB with drop bars' stance of some of the 'sliding the back wheel around downhill gravel/trail turns' current gravel bikes, and would rather skew my priority to a fast road bike (albeit not 'race' geometry) which has the wheel/tire clearance to be ridden on gravel paths.
its very much what works for you, I race a winter gravel series on forest trails on my road bike, with 28mm Durano DDs so a solid road tyre pumped up to around 95psi, always gives me a definite advantage especially on the climb sections over gravel/mountain type bikes, I usually have a top 5 finish, but would I recommend that set up for anyone else ?
How about comfort? Would having a rear suspension like for example the Berria Belador, the Cannondale topstone, or the moots Softail gravel bike help you stay "fresher" through long rides outweigh any aero gains a gravel bikes would have (considering that all other things remain equal)? Or would a more flexible seatpost be better than the complexity of frame suspension. Like for example the ergon flex posts.
Concerning aerodynamics I think that the rider position is the biggest factor and if some sort of suspension or flex aids in keeping that aero position for longer than that's better in the long run.
Just got an aero handlebar for gravel bike, (not aero bars) aero sleeves aero socks aero helmet and an aero food box. I do have aero bottles but they don’t carry enough water for gravel race distances.
I’m also going to go change my road tires and let some air out now too.
Love this full blown nerd fest!! No hipster purest nonsense, just performance driven facts 👍👍👍
Dylan, can you tell me what kinda tires you are using in this video? And what kinda camera? Is mounted on your bars? Please advise thank you !
where..? might someone find those handlebars + integrated aero?" I'm definitely looking for the cleanest way to add some aero bars to my cockpit without screwing up the carbon bars or having to swap to some alloy. that is sooooooo clean.
Glad to see integrated handlebar/stem/aero bars becoming available. Swapping out handlebars including rewrapping bar tape, rerouting cables and bleeding brakes got old a long time ago. Any idea when the Black, Inc. ones will be available? Anyone know of other options? (I thought I saw a booth at the Unbound expo featuring aero bars but for some reason I didn't check it out)
I've been checking the Black, Inc site daily for the bars!
Dylan, what are the major differences between the Ostro Gravel and the LS?
could you make a similar video for MTBs, very cool content
Having been in several races with people using aerobars, I don't have a problem with them existing, even in the race. The problem is that you get a lot of people using them while in a group. This puts everyone next to, and behind that person, at risk. Classic example of why we can't have nice things...
Yeah, but what if you get up to speed in the drops then move to the hoods but keeping your same profile. A friend said I’m hard to draft cuz I ride the drops but I’m not. I look at the shadows of our peloton and my arms are bent not locked. Best aero advantage gains is our own bodies
gotta put an aero back cover for that Insta360 camera ;)
It would be nice if you could wind tunnel test a higher rim coupled with your Specialized 42mm tire to see if it’s more efficient than your Black Inc 34mm wheels😉
Do you think you could find aero gains with higher rims?😉
When will the gravel handlebar be available for purchase?
Also front chainrings have aero penalty. By going bigger you may optimize the chainline but lose more in aero and worse front derailleur
Dylan, what are your thoughts on Classified Powershift for gravel racing?
Have you considered using 3t discus 45/40 ltd wheels that have an external width of 40 mm? They would meet the 105% rule with 38mm tires.
Ostro Gravel vs Ostro Road with same tires. This could make the case for a one bike does it all. Crit/Climb/Gravel.
Could you make a video about blood flow restriction training?
