    disc brakes on trek 3700

    i have an 04' trek 3700 and im looking to put front and rear disc brakes on it. I am planning on replacing the RST shocks with a rock shox Dart so i know i can mount the front caliper to that, but does anyone know if i will be able to mount the rear caliper to this frame. The bike also has the shimano gear shifts and levers combined, I am assuming i am going to have to replace them as well. Also does any one have an opinion on if it is even worth switching from linear-pull brakes to the disc brakes???

    Do you have caliper mounting tabs on that frame? If not, you're going to need a disc brake adapter $100-150
    you are also going to have to get disc hubs. ~$120

    you don't have to change the levers if you get mechanicals - Avid BB7s are the best. ~$130

    Whether you want to spend $300-400 (my rough minimum estimate) on that bike to get a decent disc brake set-up is up to you

    *edit - I forgot to add labor for building the wheels and possible (likely) need for spokes, and cables

    Trek makes a disc adapter for the frame, runs like $14 at a Trek LBS. That really only leaves the wheels to overcome, but they can be had cheaply enough, depending on what you want. Other issue is the front fork, the SR Suntour that the 3700 comes with doesn't have disc tabs.

    I converted a GF Tarpon, which is essentially the same bike to rigid front (Surly 1x1) and BB7's, and didn't have $250 in the full conversion, but that was doing some price shopping. I think the most $ was in the BB7's

    The fact is its just not worth it...your going to wind up having well over half of what you paid for the bike, maybe even as much after fork, wheels, hubs, and the brakes themselves...The best thing for you to do is pick up a pair of Kool Stop brake pads...

    I put a set of these on my hardrock and you can really tell a huge difference in stopping power...Heres a link

    I dunno. You shop right you still have a great bike at a price point that's low. You have to jump to the 4300 in the Trek line to get factory discs, and they're M315 Shimano mechs.

    I've got maybe $500 in this one including the bike. I use it commuting:
