First let me start with my New Guy Card. I'm a little overwhelmed with finding things on this forum, so if there is a thread for this already, sorry.

I'm looking for more top-end speed, and want to see what some of you guys are using.

I'm not racing or anything, I just want to improve the top end a little. On flat land, I can turn about 25 mph on this setup fairly easily.

Also, are you using the factory drivetrain, or is it upgraded?

Anything else you'd like share, have at it, so long as it is related to the drivetrain.
