This is what i was thinking too. This has been broken for over a year now I just been riding my diamondback. But I would really like to get this going again.This is from my memory but I recall the 5.5 and 6.5 being very odd ducks and you need a swingarm from the same model, from the same model year.
I appreciate it. I guess if I can find a decent deal on a rear section on a slightly newer one I will give it a shot. Trek told me last year to pound sand they don't sell parts for bikes older than 4 years. That's pretty messed up being it looks like that MY07 frame was used to 2009. They said they don't recommend keeping a trek longer than 4 years because it's time to buy a new one. I am sure some people can afford that. but one a $6000 bike it better last me my entire life. I have a Camry I paid $600 for that lasted longer than this bike. It is upsetting.Info is pretty scarce on that MY in the Trek tech docs but I did some digging into the suspension side of things and found this:
It looks like it might be possible to do something with anything up to alloy 10/11MY parts.
