I'm going for the lightest, fastest-rolling, twitchiest ride. Lighter weight equals faster accelleration. The trails around here are mostly tight singletrack, so a lighter bike that can get up to speed out of turns is what I'm looking for.

 Btw this pic is outdated. She's at 27.8 lbs now.

 that makes sense then. what have you changed to make it lighter? and what are you still planning on doing?

 I just uploaded two new pics with my current changes. Still to come are new brakes, handlebars, seatpost, pedals, and possibly shifter and derailleur.

 Something like that. New wheels will be in this weekend, then it's just seatpost, handlebars, and brakes left. Maybe X.0 drivetrain in the future.
