okay, i bought a trek TR30 last summer and have hated it since, it wont stop flatting.i actually( after the third tube) took off the rim strip to look for anything!(nothing) and of course i checked the treads for debris but that didnt help! i put on a new tube pump it up and its flat in half an hour! i checked the valve stem,rims,treads, size and nothing is visibly wrong! even bought tubes from diferent supliers at diferant stores! nothing! still flat!
but to the problem on the title. the brakes it comes with ive never seen before. calipers with two brake lines? im used to linear pulls and disc's! they stop great. this one takes half a block if i squeeze white knuckle! is this normal? the guy i bought it from said it was. but he wouldnt let me return it the next day! i hate this bike! no offense but i wish i could afford another mountain bike! trek has soured me to BMX! advice!?
(p.s. always make sure you test ride a bike PLENTY before you buy it!... duh!)
