Yes, I'm glad that TREK has OCLV in WSD. When I got my TREK I had a choice of their then top of the line in 47 cm, or the TREK 420. New to riding and not sure how I'd like it I got the 420. Since then I've upgraded wheelsets and have the Mavic Opensup Pro rims and a whole lot o' other fancy-schmancy stuff on this entry-level frame. Yes, wheels make a difference, not so much in comfort but acceleration, handling, less rolling resistance, more zip and pep.

My partner had a Cannondale and threw good money after bad to try to make it comfy; fat tape, thicker tires, new rims, suspension seat post, you name it...could have bought a whole new bike ;-)

Finaly...she did! Her Mondonico Futura Legero has all day comfort that you get from steel and get this, it's lighter than the aluminum bike that is now just used on the Cycleops!

Our vote is steel if it's comfort you want but as always whatever the frame material the most important thing is fit.
