That's just madness... Dave. I just measured mine up at its 17.5 centre to top. The offers still open if you decide you wanna give it a shot for a few weeks...
Besides that though, they are superiorly priced and a bargain. Today I dropped the psi in forks (Xfusion Swoop Boost in 140mm guise) from 77 to 75 and it seems a different beast. Stopped smacking me about on the rocky descents and I'm loving it. Probably (sorry for my bad grammer and I know my sentence structure needs work), my bestest bike of all time was my Santa Cruz Superlight with 130mm Mag Menjas on... But this, I'd say is probably on a par...
Anyway, good choice in getting a (reasonably priced) carbon frame. They're ace
