going to go to a 25mm Tire.....OLd man style??

Road Cycling It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle. -- Ernest Hemingway

going to go to a 25mm Tire.....OLd man style??

I ride a Bianchi C2C full carbon all 105 nice bike but I need new tires. I am debating going to 25mm tires for more comfort. Anyone use 25's??

Lots of people use 25s. Some use 25 on the back only. I use 25s and don't think I'll use 23s again.

My Giant Defy 1 is probably not as race-sexy as your Bianchi; even so, the 25's are as small as I wish to go with the horrendously varied quality of the streets on which I frequently ride. I tried 23's on my previous bike, and the ride on the aforementioned terrain varied from uncomfortable to scary.

If you ride mainly on nice, smooth streets, with very few transitions between different pavement material, driveways, and such; or if you use your bike for competition, then the thinner tires should offer a better, faster, and more efficient ride...

I used a 25mm gatorskin on the rear of my winter bike (An aluminum Bianchi). It just barely fits as there is little clearance between the tire and seat tube. I have to jamb it in to get it to fit so you might want to check how much clearance you have to begin with. The 25s will be larger diameter than 23s. Not sure I notice much of a difference in ride but it seem to work fine.

I ride 25s. I like them more and seem to get less flats then I did when commuting on a 23. I dont know if this is just luck or if it actually made a difference. They are comfortable and I'm sticking with em.

I ride 25c on all my bikes also. This includes a 2011 Trek Madone 5.9. Did over 75 miles on the Trek today with those tires in perfect comfort. Oh, and even though it was a solo ride this old man managed to average 19.2 mph on the ride so 25c tires are not slow by any means.

I got a pair of 25mm Gatorskins on a wheelset that I bought last year, and have been riding and racing them all season. Nice ride and no issues. It's about time to re-up, and I'll probably be going with 25's again, though not Gatorskins.

I'm on 25mm tires right now because the tires were on sale for a great price in that width only. No problems. As a matter of fact, I can't even tell the difference.

I read a recent article (RBA magazine?) where they claim 25s are faster than 23s due to the fact they would deform less at the same tire pressure.

Yeah, I read that as well as discussions on this forum, and came to the conclusion that if the arm chair engineers were right, the pros would be riding 25s or even 28s all the time. fwiw the theory requires that all other variables are equal, including air pressure.

Less rolling resistance but more aero drag. Not necessarily faster.

Funny. I was wondering that as well.

I use 23 on one bike 25 on the other can't really tell any significant difference.
Maybe a little on wet road.

I can't tell the difference between 23s or 25s as far as comfort goes. The real reason I'm riding with my 25s is the durability. Only one flat in about 3k of riding.

I reached 47.7 mph on the short 6% grade decent near my house last week on my Gatorskin 25s. It's not a straight decent either. If your worried about performance (and not competing in the TDF), don't be. Most people aren't going to be able to tell the difference unless they put in some serious time on their bike.

If 25s are "old man style", do my 28s make me an octogenarian? I'm only 42!

Regardless, go big. Much comfier, which equals more smiles per mile.

Riding a long ride this weekend...80mi (130kms). Going to put on 25s at 90ish PSI instead of 23s @ 105. Think it'll be worth it.

I have a 25 and a 26 (Panaracer Stradius) on the Pinarello at the moment. I've been riding primarily 25s for some time except when I get some decent 23s on super sale - ran through a couple of 23mm IRC Red Storms for $10 apiece a while back. I still keep one as my spare for solo centuries and such.

23mm on the sewup wheels ATM

I've used 23s, 24s, 25s at 100-110 psi and haven't really noticed a big difference. My cross bike has 28's at 100 psi and feels much smoother (without being dead), but I don't think that is due exclusively to the tires.

Also manufacturers don't seem to abide by a standard (still). My Specialized All-Condition 23's were slightly wider than my Conti GP 24's.

24mm Conti Force Rear, 23mm Conti GP4000 up front, happy with the setup.
I'm also running Latex Tubes, softer than Butyl IMO

I'm on my 2nd set of 25s. I didn't notice a difference but after a month, I realized that the pain in my shoulders on long rides was gone.

I don't know that that proves the point. Pros get paid to ride certain things and are superstitious. Pro baseball players may wear the same unwashed jock for days on end when things are going well, but that doesn't mean there is a cause and effect relationship

Not too long ago 21mm tires were commonplace. Even 18s could be found. No mas.

Now a lot of tires are undersized. Last 25s I got are totally 23s
