New brakes or not?

I have a 2004 Trek 6700 http://www.trekbikes.com/us/en/bikes/2004/archive/6700
It still has the V-Brakes that it came with. Is it worth upgrading to disk brakes and how much am I looking at to get a decent disk brake setup? Is there going to be that much more of a need for the disc brakes over the v-brakes?

They way I see it, the power of the disc brakes is not its primary advantage. Disc brakes modulate better, and they perform better in muddy and wet conditions.

That said, you can get a set of Avid BB7's for your bike for about $120.

your concern is less about your rims and more about your hubs. Your hubs, fork, and frame all have to be disc compatible.

After looking at the archives, your fork looks like it's compatible. You'll have to check your frame for disc tabs. Your hubs should look like these, with 6 holes drilled on the left side for the rotors.

I get what your saying. If my hubs need to be replaced for this, which it looks like they will, then I will go for a whole new wheelset!

I did this upgrade on my 2003 Trek 4500. In addition to the disc brakes (Avid BB7s are highly recommended) and disc-compatible wheels, I believe for a 2004 Trek you will also need a special adapter for the rear caliper mount (as I recall, 2005 and newer models do not need this adapter). Replacing V-brakes with discs will run you about $300 for the brakes and wheels, plus some shop labor if you are not "handy". You can use your current V-brake levers.

Expect only modest improvement in stopping power over properly adjusted V-brakes when dry -- but significant improvement under wet conditions. You have to decide if disc brakes are worth it to you -- I believe the 6700 is worthy of the upgrade.

OS, where can i find the adapter for rear caliper mount? i'm working on my 2004 trek 4500's conversion right now and @ the moment, i don't have a rear brake.

TIA
