I just upgraded to the new kh 137mm trials, and had them built into my bedford light (replacing the bent cranks I had been riding on since the night I got it) and I’m wayy happy with them. I went downtown in Asheville yesterday and we got a bunch of video that I’m putting online today.

I must say woo. I don’t even notice a weight difference, and they are seriously tough. They make tricks easier for some reason. Maybe it’s the longer crank length (125’ before). That and there is no flex when I jump, and no detriment when I land.
