For our conversation: I bought a KTM strada with old 23 mm and changed them the 28mm . Two problems appeared. One there was not enough clearance so you could occasionally hear some noise scratch on my front tire. Second problem it was the changing of the gear ratio. Small difference but specially when you climb with 12-27 became 12-26,5. After that I went to 25mm and it was much better. Two week later I bought a used shimano wheel set RS20 with 23mm tires so I have the choice to change them immediately. My final conclusions with my low budget but a aggressive bike are the following: 28 mm: They provide a smoother ride or faster in a tough flat terrain because it make a smoother ride in a road with potholes. But if you try to climb you need instant acceleration and a good gear ratio that the 28mm tires haven't because of mass and the change of the gear ration compare to 23mm. 25 mm. I think they are the the best choice. Specially today that 25 is the new 26 mm. The provide a fast aggresive accelaration with some compomise to a comfort but not as the 23mm and they don't change the gear ration of the bike so much as the 28 they do. 23 mm: I like them. I use them for hard climbing and not in a big distance trip. Fast, responsiveness and you have the feeling of participate in a race. 32 mm: I put them on my old steel bike because there is enough space for them. I'm not sure that i like them even if they are much smoother. FOR SURE are slower. My final conclusion is if your bike has aggressive geometry you can go to 25mm tire with no problem but no to 23mm. If it's has a slack geometry 28-32 are perfect.
Thank you for great review. I tryed to look for bike with clearance for 28, but in November 2018 there isn't any bike with race geometry which fits 28 tyres safely. Reviewers said that Cannondale Supesix 2018 up to 28 tyres. But in real life I don't know. Maybe it fit, but clearence would be very low for using. I think we have to wait some years to see bike with race geometry which fit all 28 tyres, probably light disc brakes and with adapted ratio gears. Today if you wanted to use 28 tyres you would buy endurance frame. That is our reality.
@@comedyman112 I just an older bike with 23 tires,feels like a boneshaker sometimes, planning to get 25c soon as,local bike shop said will fit mine,if still unsure pop into local bike shop
Wait till you go the 28 in the rear, the gear ratios change considerably ! Its definitely harder going for a given gear uphill compared to the smaller tyres. Jimmy
Continental ultra sport @ $20 each tire in 25c is my spare tire budget tire. Feels soft enough vs the rides like a brick gatorskins or armadillo brick tires. And the ultra sport is only $20 a piece. They feel like an unfinished slightly heavier gp4000sii tire but budget friendly for sure. Plus it has good grip in cornering. I run them at 85psi.
I had 23c tires and there is this stretch of road I take on my commute. I was getting beat up badly. Bike couldn't track, couldn't maintain speed at all. Switched to 28c on that same road, it felt like night and day. I could never go back to 23's either. And I got far less flats.
Exerlent buddy .. I've just gone from 700c 25 to 28 .. continental Grand Prix 4 season .. and wow the difference is Amazing .. lot smother seems faster ..more comfy I'm happy and so is my cannondale... cheers Chris Sam
More comfort and better road handing. I just changed my tires to 25c on my 2015 Cannondale SuperSix Evo. More grip on the road then I feel my bike goes faster.
Still trying to figure out how switching from 28c to 23c caused my speed and average to increase. I tried the bigger tires and they felt sluggish and heavy. I’m sticking to my 23’s. Felt like I was driving a bus with those larger tires.
One of the reasons larger tires feel more comfortable is because you can lower the pressure to 80 or 90psi. Can't run that kind of pressure with 23mm or you would get a pinch flat.
Totally agree! I use 25 mm and have far less pain after my rides. And also agree on the lights. Both front and back. The front ones have saved me countless times from idiots trying to make left turns out of a street on me!
It's about the smoothness of the terrain, the rougher the terrain the bigger the tire needs to be otherwise you loose energy, (the bike starts to vibrate to cover the gaps). track => 20 mm ~ 9 bars smooth tarmac => 25mm ~ 7 bars average tarmac => 28mm ~6.5 bars just as an example 28c carries a huge weight penalty to competitively go uphill btw
jen Continental GP 4000S II folding tyre 23mm weighs 215g and 28mm weighs 235g. A pair of 28mm weighs 40g more than 23mm, which is not even close to being a ‘’weight pentalty’’ for anyone except pros.
dzgnned agreed. That is not even a weight penalty, especially for average riders or even riders who are really fit. I much more prefer the comfort of 28’s and honestly I can’t feel a difference while climbing.
James hi, I was thinking of putting 28 tyres on my 2017 caad12. I read your comment and wondered how much clearance was left when you fitted the 28s. Cheers.
Appreciate the safety alert, motorists in the U.S. no joke when it comes to endangering cyclists for no good reason, that is the case in NYC and LI anyway.
Idk about the Nitro 2 but the front one is trash. I had a brand new pair of 28mm and kept them inflated at around 85-90psi and you could see the rubber slightly splitting all around the sidewall. I thought eh no big deal its keeping its shape and the spits are pretty small and shallow. But then the rear tire got a split right above the bead and a bulge could be felt on the sidewall. I read all the terrible reviews and thought maybe theyre just overinflating them but nah they're just no good
I'm currently riding on a 28mm 85r-80f at 130 pounds, feels alot better then 90-100 psi as that was a bone jarring ride if I hit any cracks on the road . What psi would you suggest for a person at 130 pounds ?
JoeCycle - yea your about spot on I tried 80r-75f the other day and 75r-70f today. Though the 80-75 feels faster to me the 75r-70f feels so much comfortable. I think I'll go up just a hair and that's probably the sweet spot. Thanks!
This really doesn't hold water. Measurements are going to be different based on the inner rim width. I have rims that are 22mm inner and 29mm outer and 25C tires inflated to 90 PSI come in with a width of over 27mm. Someone who has a rim with a 17mm inner and uses a 25C tire may not even get 25mm.
In most cases yes. If you have really smooth roads and you ride a lost of climbs 25mm might be faster. But generally speaking, we don't have perfect smooth roads and we don't always ride climbs alone... In a mix of normal roads and climb, flats, decends, 28mm is faster.
For ten years I've been using 23/23 for front/back, feels very comfortable but it's indeed a little dangerous when taking tight corners with the less grip. Is it better for me to change to 25/25 or 25/28 for front/back? Thanks, regards!
stackedhippiechick I don't run super high pressure for normal riding. 25mm at 90psi 28mm at 80psi. I'm about 200lbs so if you are lighter you can try little lower. on group rides where I want to be a little faster I will up the psi 5 to 10. thanks for watching.
let me know how it feels and compare once you have done over 60-mile rides. wider is actually faster and smoother... There is a reason why most pro's now run 25s.
wider is faster in case you've got the carbon (and expensive) wheels the pro's have. In any other case you stay with some heavy wheels and wonder what's wrong with your performance
wait... are you saying that wider is only faster if you have lightweight carbon wheels... WTF, where is your logic... we are only comparing tires not rims... assuming your logic then the pro's would be even faster with narrow light weight tires compared to the 25's they run.... It's about rolling resistance man... so wider is faster as it's a lower rolling resistance, don't take my word for it. look it up. real life tests show that tubeless 28's are faster than 23's ( lower rolling resistance ) nothing to do with how light the rim was, or if it was made out of carbon.
ok get your ordinary rims, set a 28mm or even bigger tire and with an additional rotating mass of more than 100 grs per wheel, try to roll faster on a climb of 4% or more...get your results and let us know
well why not run 21 or 19's than.... let's all listen to your logic and not listen to the pro's that are all about marginal gains.... yeap makes sense.... pro's are wrong running 25's and larger for some races and go back 10 years to the era where thinner was better...

Less rotating mass. Lighter weight.
There are probably hundreds of reasons why that happened. Are they the same tire but different size?
One of the reasons larger tires feel more comfortable is because you can lower the pressure to 80 or 90psi. Can't run that kind of pressure with 23mm or you would get a pinch flat.
taurus20077 so, 23mm ones have higher pressure?
