Mountain Biking - Need some advice.

ok so my setup is a mostly stock trek 4300, not new.

I was looking to get some disc brakes because the trail i ride on has quite a bit of streams and mud, which my v's don't tend to agree with.

Much to my dismay, I come to find out from my local bike shop that it'l run around $500 for the set of avid bb7's i was looking at and new disc ready rims. They showed my a new gary fisher wahoo for the same price with discs and said that was the way to go.

So i go back home in deep thought and find on ebay i can get front/back set of bb7's for 110 tops and what look to be a good set of rims for 100 tops.

I do have 500 if i sold my trek, but i like my bike even though I realize its not the greatest.

Any suggestions?

Are your fork and frame disk compatible? How 'bout just putting disks on the front and leaving the rear V? That'll save money, and you use the front brake more than the back anyway.

Treefortbikes had the BB7's for $104 shipped...

The Wahoo might have discs, but they're no BB7's. Plus, the wheels it comes with probably won't be as good as the $100 ones you found.

You don't need discs for "streams and mud", but if you really want them then buy the Avids and put them on the Trek. You'll be better off upgrading the brakes yourself than buying the Wahoo.

Chris - Good idea, except I think i'll do the oposite because i use the back brakes more

kramnnim - also good, but my bike shop was talking about a basic wahoo, and then adding bb7's in their shop

251 - true, you dont need them for streams and mud, but i realy don't like loosing power everytime i hit one, and cleaning the rub-off off the rims after everyride to keep them workin

still not sure what i'm going to do, although leaning more towards the upgrade route

You should use the front brake more. I'd say 85%-95% of your braking power is available via the front brake. The back is mainly good for skidding the rear tire around.

hmm might give that a try
