Fixed Gear Off Road Shredder

Thanks, Eamesy.

I think I would gather a few chain rings and sprockets (and chains) and work it through on a trial & error basis, adding in some science as you get to know how easy/difficult it is to ride over different terrain. Personally, I would start low (46x20 or lower) and work up. I don't know how you ride or how strong you are. Also, you'll work out what is the best compromise. If you're only going to be shredding the trails, I would go lower (although, expect some speedy feet on the descents). If you'll be mostly on road, you'll need something higher, or you'll just get frustrated. I reckon you may want to try a lowish free gear. That way, you can climb pretty well and run less risk of tangling your legs up. But, I hear you say, where's the fun in that?!?!

Good luck and have fun experimenting!
