I've been using my 2008 FX2 for a few years now commuting to work (24 miles round trip) and have upgraded a good bit of her along the way. Race Lite stem, race lite riser bar, race lite seat post, race lite wheels, ergon grips and bar ends, RXL saddle, bontrager rear rack and panniers & added some well go spd pedals that I've had since I traded my mt bike years ago for the FX. The shifters, derailers and cranks are all still stock and working well due to good maintenance on my part.
The FX has been a great bike for me but I'm thinking of upgrading to the Trek Crossrip with disks. Has anyone had a chance to compare the Crossrip to the FX as I'd like to hear some comparisons.
