Well, I'd be interested in knowing what other people think of the way it rides….
Having just been out on it, it feels very short and upright compared to my Trek Fuel Ex. Upright to the point of feeling like I'm using odd muscles pedalling up hill. Hard work uphill. A bit of an enigma because its fairly light but I just couldn't get it going fast uphill.
Down hill it felt much better and fairly lively on singletrack.
Going to try and lengthen and lower the cockpit, but it felt like the pedals were in an odd position compared to the saddle, and I set it up so I was in a fairly standard position. The effective top tube is at a push somewhere between 22 – 22.5", don't know if this is exceptionally short for a 'medium'?
