  1. VERY much on my radar. These and the Nano 40. 3/4 of my riding is on roads, so needs something that spins great, wears well, yet has some knobs for when I get to the dirt. Clement MSO seems best in those regards till now, but these GGs really look like they could be a touch better on the road thanks to the center tread. Post results!!!

What's on your mind?
