I put almost 23,000 miles on my last fixie road bike from Bikesdirect, a 2008 Dawes SST. It came to an end a couple weeks ago when it was hit by a car and totaled. In all those miles I replaced the chain, chainring, cog, bar tape, and the rear wheel once at about 15,000 miles. So I bought a new fixie from Bikesdirect, a 2015 Mercier Kilo.
