I have a full suspension 29 but there are some trails in my area that are smooth, hardpacked dirt and teh 29er feels like a sluggish pig on them. They have small hills, small climbs, small decents, not really any roots or rocks to worry about. They build these trails in small areas so they are packed with very tight, twisty turns with trees at every apex. What kind of bike would make these trails fun? Dirt jumper? They seem to have the handling charicteristics I'm looking for but I'd prefer brakes on both wheels and a saddle I can sit on and pedel. I don't want to spend much on this bike since we have to travel to hit these trails, used would be prefered. My local trails are much more suited for my full suspension. All my friends like these other trails though so we take trips to hit them up, but I think they're going to build one locally so I'd like to have something a little more suited to that style of riding.
