I'm thinking that this bike might be OK for use in a trainer? About 18 months ago, I was involved in a bike on bike crash. The frame on my 2008 Trek Madone 5.2 was damaged. I enclose pictures of the complete bike for illustration purposes. This really a complete bike less the frame, pedals and seat and you could sell it for parts. The drive train is 10 speed Ultegra. The rear derailleur is the short cage RD 6600. Front is a compact 50/34 original. 172,5 mm cranks. Besides both derailleurs, the package would include chain, cassette, bottom bracket and shifters, wheels also included with the caveat that they don't match (as shown). The original rear Bontrager Race Lite wheel cracked in 2013 as well but Trek authorized a replacement RL. The RL can handle 10 or 11 speed cassettes. The package would include the fork, seat post, brakes, bars, and stem as well as the wheels.
