I bought some $72 Walmart special and it's never let me down. I just need a wider seat. Seriously chafes my ass every time I ride it. But it's never broken down.
Which one? Is it the NEXT "Valet" ? That's what I have. Never let me down, and I use an extremely thin $100 Racing Saddle (It may hurt at first, but that's probably because you haven't thought about
not leaning on your balls yet).
@Ghoul: I've tried Mountain Biking, I only seem to like downhill. Getting back up is a pain in the ass.
