Edit: This is now definitely for sale.
I _might_ be selling my CX bike. It's a 58cm 2012 Trek Ion CX, in decent condition. More details on spec here - http://www.trekbikes.com/us/en/bikes/20 ... rek/ion_cx. It was serviced about 6 months ago, including new chain and BB, but done less than 100 miles since.
I'm undecided about selling it, but it may be surplus to requirements as I'm probably not going to have many chances to do CX races, and I'm also toying with the idea of turning my fixed gear bike into a single speed CX bike instead. And the cash will help fund TT plans for next year.
It's got a proven pedigree too - this bike won the Hell of the Worth 2013! It's been slightly less successful at CX races, but that's mainly due to the pilot rather than the bike There's a review of the Pro version (next model up - same frame but higher spec components) here - http://road.cc/content/review/71571-trek-ion-cx-pro
As I say, it's tentative at the moment, but if there's interest (looking for around £550), let me know.
