how many fingers do you use on your brake lever and what's the difference between mod's 20" etc etc. I'm new to this forum and tend to ride on my own, my mates don't see what is so good about hoping onto stuff, so don't really no what everyone else is riding bike wise etc etc. if i use my two fingers on the lever it to powerfull and i then don't have enough grip on the bar for jumping. if i use one finger for braking i have enough grip but not enough braking power. i have a onza T-raptor with HS-33's. can anyone help? cheers
