You know you're only supposed to bump topics every 24hours. Not minutes. Anyway, is it for a mod, stock, 24", 26" Mod? (Guessing Mod, as your profile says so) If it's for a mod, and you have enough money, I'd say either go for a rear Profile and fixed front cog set-up. I have a Profile on the rear, bought it 2nd hand so it'd already bedded in. Hasn't skipped at all (i've had it months) never had to service it or anything. If not, go for something like a Tensile/ENO (Tensile's cheaper) freewheel up front, with a fixed hub and cog on the back. EDIT: Oh yeah, frames. How much you got to spend? Short or long? Any particular 'style' you want? Long - Zona Zip. I have one, and fecking love it. It's nice and flicky because of the short chainstays, and is perfect for everything. - Sidehops, gaps, front to back, spins etc. Seems pretty strong too. (Only the proto Zip frame has snapped so far) I prefer long mods. Being 51 11", I seem more comfortable on a long mod, then I do on a T-Pro. Not as cramped. Short - T-Pros are nice. I had one before my Zona. And it was very good for learning on. Geo was nice too. Nice and flicky, and good for gaps etc. I cracked my one though... Monty 221pr - Pretty cheap frames. I think they're exactly the same as the 221Ti (Apart from colours, and the complete builds) I've read so many good reviews on them. And I haven't heard of any cracking or snapping. Echo Lite - Everyone seems to love these. they say the geo is perfect, and is really nice to do everything.
