2010 Tire of choice will be from Maxxis. It was a tough decision but in the end the chance to run a 285 gram tire is to good to pass up. Running those will save me 1.5 lbs on tires alone. Match those up with the new 1x9 setup and my bike just got 2.25 lbs lighter... 17.75 lbs should make for some easy climbing. Thank you Maxxis.
