Helped with bike fit

I bought a Niner WFO E9 which has a little outdated geo, for me, too short of reach. I wanted to get a longer stem, but had to be careful not to slow the steering or raise the stack height too much. I bought this in a 70mm and with the 8 degree rise it worked perfectly.

Good finish, cool design and light for a trail bike
