I just finished my lastest build. It is based off of a '01 NRS frame. Xt drivetrain except for the rear and the chain. I went with sram' X9's series on that. The seatpost, crank, and stem are all Race Face Evolve XC. Couple all that with a Manitou Splice Super and some Azonic Tracker tires. let me tell ya. those tires rock!!! I went the TekTro Mech Discs though. I will upgrade to Hydro's in the next couple of years. Right now I want to change out the rear shock with a Fox RP3. It goes uphill real nice and downhill it dose fine too. I love the stiffer susspinsion in the rear. It really fells good.
