Suppose I'll comment on this.

I'll be running 13/50 at the end of the week. Currently running 14/45 and I don't got any giddy up and go on the tighter technical trails in Japan. Always at risk of stalling out due to low RPM.

My new 50t rear should arrive towards the end of the week, and the 13t is just waiting for me to get the rear so I don't waste my time..lol Will update when I get it..haha
