I am very very impressed! Very good review!
The most in depth analysis , my respect to you sir I got more than what I was looking for and then some! This is what sets people apart, knowledge! Thank you! For sharing it.
Thank you very much for the kind message, it encourages me to continue to make videos.
Cool and thanks for the explanation my friend
Just put together a frame n fork with the R7000 group and been loving it. Combined it with R8000 calibers. Great set-up imo.
Good vid.
Wow very nice! Did you end up going with disc brakes? My hybrid system disc/rim brake bike is working well.
@@pedalpowercycling No disc. R8000 Ultegra rim calipers. Excellent stopping power combined with Oval Concepts 527 aluminum road wheels.
Reason for viewing this video I recently purchased a vintage Colnago C40 with Dura Ace group set then a friend pointed out that a Campagnolo set should be more appropriate for such a bike, I don't mind either way I bought it for the art in it but his comment got me thinking, your video helped me on my decision Thank's!
You're welcome, I have an american made Merlin titanium bike with a full Campy group. Mix and match works well.
Thanks for sharing this
This was handy to see as I am looking to see if swapping out a 7000 105 for a used dura ace crank is worth it - thanks for taking all your crap apart for us. Lol.
You're welcome, I also uninstalled the cranksets from the bikes and then reinstalled them. =-)
I enjoyed your video but you completely missed talking about the outer chainring compatibility. I have a project where I'd like to install a 54T FC-R9200 chainring on a FC-R7100 crankset. I've been searching for an answer and coming up blank...
Correct, my video specifically was regarding weight comparison. I could pull off the cranksets on the bikes and make a chainring compatibility video in the future.
i see it now!
Good Job!!
Any ideaz if I can use the Dura Ace pf bb86 with the 105 crankset? Thx~
It depends on your frame. If your frame is bb86 compatible then this 105 crankset will work with it.
hey hi nice review btw will the dura ace small ring and large ring will fit to a 105 5800 not R7000 CRANK arm? Thanks
I don't have the 5800 so I'm not sure.
I have the most current 105 that came with my Emonda sl. can I use a dura ace crank on my bike with 105 components ?
Yes, you can. I have ultegra di2 with dura ace crankset.
Does dura-ace crank will compatible to claris 8 speed ? If I gonnto put it ? Thoughts ? My crank is 50-34tt. Thanks
Maybe but you'll need an 11 speed chain.
Sir pls make a video of shimano dura ace or ultegra crank 3X big
The rare triple chainring crankset? what would you like to see? I have them.
Could you run an 11 speed crankset with a 10 speed cassette and chain? I’d like to see the differences between the 11 speed crankset and a 10 speed one.
You can but I'd recommend an 11 speed chain even when using a 10 speed cassette. This is my setup: 10 speed di2 with 11s dura ace crankset. 11s dura ace chain.
yes you can, I'm running the R7000 crankset (11speed) combined with 10 speed Ultegra 6700 components.
Hi, is the big chainring of DA9000 interchangeable with the R7000?
Great question. I'll have to check and get back to you.
I took a look at the chain rings and the bolt pattern is similar between 105 ultegra and dura ace. Although they should be interchangeable, I'm not sure if the rings are compatible. It depends how far each chain ring sits from each other and that determines if you get clean shifts. That's a great idea for another video in the future. Thanks
No they aren't compatible because the R7000 crank has a small angled part where the chainring fits on the crank, just on one of the arms, so it will only take R7000 R8000 or R9100 rings, but not 5800 6800 or 9000 rings.
Are you keeping the 105 crankset? I'm looking for 165cm.
Yep it's a great crankset.
Right strange question but I have a 6800 crankset and recently bought a 4iiii single side power meter on a 9100 left crank arm. I ran this combo and it seemed ok, then took it off until the weather improves. my question is in regards to the 0.6mm q factor difference where is this q factor change derived. axle or is it the flare of the cranks themselves. seems to me like i might have 0.3mm narower on left hand side of bike if its from the flare of the crank... Any idea??
I'm not sure either. With such a small difference I don't see a noticable difference just by looking.
@@pedalpowercycling Thanks for reply. I was looking into a pedal washer to even it out they are 0.8mm I realised that the diffrence is pointless small and I should just forget about it :)
@@user-oy2xy8gg5l Yes I'd forget about it. Unless you're a robot with calibrated legs, you won't notice the difference.
Will the Dura ace 50t chain ring fit on the 105 crank arms?
I'm not sure, I haven't personally tried it.
ultegra is only 30 grams lighter than 105. I highly recommand ditching the ultegra cranks and go with the 105 cranks because how often Ultegra+ fail at the glued junctions. 105 is constructed from a single piece of aluminum so it won't seperate like Ultegra and Dura Ace cranks.
I've using all 3 cranksets for over 2 years now and (knock on wood) no failures.
I agree... the 105 seems to be a more durable entity, and I swear they are more rigid. I use 16mm pedal extenders, and I fee the flex in the Ultegra cranks, but not the 105. I decided to sell my collection of Ultegra and DA crankset. I bought extra 11sp for the next decade.
It's really hard to spend 600 (DA) or 320 (Ultegra) over 120 euros to only save a few grams.
I can even replace the whole 105 crankset 3 to 5 times if it wore out sooner than the high end ones :/
You're right, I don't notice my Dura Ace being more stiff or feel the weight penalty of the 105. There are other upgrades you can really feel the difference, like a better saddle, better grips, nice clothing or something else.
Great video, thanks very much for sharing! I am currently running a Shimano 105 r7000 crankset. I am looking to upgrade my large chainring from a 53 tooth to 55 tooth. Do you think a 55 tooth Shimano Dura-Ace 9000 chainring would be compatible with my existing r7000 crankset? Thanks!
I'm not sure, someone in the comments mentioned that there may be a tab preventing such from happening.
Sir that crank have 3X and how many teeth if it is 3X.?
No, Shimano doesn't make 105, ultegra, or dura ace 3x as far as I know. They may make a sora or tiagra level along with Alivio.
Looks like minimal weight difference, and with the delamination issues that dura ace and ultegra face, you're better off with 105. Anyway, that's not where the tech is. That's more on the deraileurs, brakes etc... so keep your money for those.
I feel the real tech is in di2, it sets a new standard of shifting.
@@pedalpowercycling Just upgraded my bike to Di2 and I agree with you! Live changer. Now, when they figure out to get rid of the front derailleur altogether but still give you as many gears (or range) will be next level! Check out what Classified is doing with their Powershift hub.
14:39 lol, same weight as my 170
This review misses the point entirely. How stiff are they relative to one another?
My video was specifically regarding the weight differences. They're very similar in stiffness. I can't tell the difference in stiffness from each other. You may need a pro rider or some specialized equipment to determine stiffness.
Yo prefiero la 105.
Shimano wants you to not mix them up.
They also don't want you using mtb derailleurs with road shifters but I'm doing that anyway.
