    it can do it all...

    I have done a couple of easy spins on the M.1 and one really solid MTB rip. I have ridden and raced mtb for years. Cat 1 for MTB and raced a ton of XC and endurance MTB races with some pretty good success. Most of my racing has been on XC oriented MTBs, both hardtails and full suspension. This bike with the geometry, 120 fork, and dropper seatpost is unlike anything I've ever ridden... in a good way. It's quick and efficient climbing but then due to the geometry (slack front end and 120 fork) and I feel I can let it rip more wide open on descents than the typical XC hardtails I've raced/ridden. Being so light it climbs as well as any bike I've ridden. I am looking forward to getting more miles on it over the summer and jump into some MTB races as well. I am looking forward to pushing the limits and finding out what this bike is capable of.
