How much clearance does the 54 give you? My two Peugeots are a 54 (too small) and a 57 (too big); both the Capo and the Bianchi are 55 (just right). If the 54 fits you well, the 57 will be too big, but if the 54 is a bit small for you, the 57 may be fine, particularly if its too tube is not too long.

To make my PKN-10 comfortable, I had to resort to a very short-reach handlebar stem.

It all depends on alot of things. Frames are measured differently and TT length matters alot.Seattube angle also factors in. I ride a range of nominal 57 to 60,but the TT range is only from 56.3 to 57,and the seat angles are essentially the same. Stems handle the small differences.I've had other 60s that were way too big(even some 58s) and can think of 57s that would be too small.

54cm in compact or traditional geometry? Is the 57cm compact or traditional geometry? To give you an idea of who rides a 57cm though, I'm 6'1 with about a 35" actual inseam and am supposed to ride a 57cm ideally.

People that know anything actually consider the virtual seattube measurement,and don't get hung up on the compact traditional business.Then they look even harder at TT length. Bianchi says if you ride a traditional 57 Bianchi, you also ride a compact 57 Bianchi, as they use the virtual reference.

Bet you didn't get that from the Grant Petersen school of fitting. And a 57 measured how and with what TT length and seat angle??

Would I be able to ride the bike ?
What should I do (stem, seat post) in order to ride it ?

I used to ride a 53 cm (inseam = ~80 cm) road bike and wanted to know if I can ride this bike using a 26 x 1.0'' tyres - This way the bike will probably fit me
What do you say ?
Thanks

I just saw an incredible frame that is 14'' (c to c) and top tube of 20.5''
I figured out that my c-c frame should be 15.76'' (80 x 0.65 = 52 - 12 = 40 cm)
Since its a great deal, I would like to know if I can still ride the bike even if its not the optimal size for me
Guy
Every post (and cross-post) you have made has been can I ride a bike that is not my "ideal size?" You have now asked about a 9 cm spread of bikes (48 - 57 cm)? Are you just looking to get a good deal on the bike regardless of fit? My advice to you is to try the bike out before purchase. If you are comfortable on it, and it fits well, then by all means get it.

Isn't that pretty much what everyone has said so far???
