Can anyone explain the wierd sizing of 456s?
The Reach between the 16″ and 20″ frames differs by only 14mm – the 16″ and 18″ by only 3mm. In my book that’s half a size between Small and Large and no discenable difference between Small and Medium.
I did recently buy a C456 in 20″ guise as I wanted to have a longer bike with shorter stem but don’t really like the gate-like proportions and am wondering if the 18″ would’ve been a better option.
Rides great though.Posted 6 years agodeviantMember
I e-mailed on-one earlier in the year when i was considering a 456, told them i was 5′ 9″ and the official response was to always buy a size too small as its easier to enlarge a small bike with longer seat post, increased layback, longer stem etc….i reckoned an 18 inch was fine for me but they said a 16 inch frame would be better….going by on-one’s sizing policy i reckon you’d need to be some kind of gangly freak to need a 20 inch frame!Posted 6 years agoIHNMember
6’1″ (33″ inside leg, vaguely gangly arms) here, had an 18″ with lots of (layback) seat post but always felt a bit little. A weeks riding in Italy finally proved it, I felt like I was falling over the front of it on steep stuff.
Bought a 20″ frame, much much better, and the saddle is now pushed most of the way forward on the post. So much so, I’m thinking of sticking a straight post in it.Posted 6 years ago
Thanks IHN, we share the same vital statistics (I think). 20″ good.
My post is pretty much in-line and is good with an 80mm stem.
The stated sizing on the web-site, then, is obviously rubbish if there is a good difference between the ‘real-world’ sizing. (with reference to reach, that is)Posted 6 years agosingletrackbikerMember
Had a steel in 18″ & ran straight post & 70mm stem, bought a Ti & dropped to 16″. 5″10, 32 inside leg & run a layback post (the Van Nicholas Ti post). 70mm stem currently, although I’ve found that while the bike feels great in 140mm travel, when I drop forks to 100 or 120mm, I do feel a little too over the front. Tempted to try a shorter stem when running less travel, but in reality, I’n happy running 140mm over most terrain & bike still climbs better than my legs will keep up with currently.Posted 6 years ago
