Awesome bike, gears are overrated

Incredibly light, fast, and we’ll spec’d.

The geometry is great for climbing and going down any front range single track.

Super service and experience dealing with Spot bikes!

Really nice ride!

This is my 4th singlespeed and probably the happiest I've been on the first few rides of any mountain bike over the years -- singlespeed, hardtail, full suspension, carbon, steel, aluminum. The belt drive provides impressive power directly between pedal and wheel. The geometry and dropper combine for a fast, nimble and versatile ride. The 46:29 is like 32:20 on a chain setup - perfect for me but you might consider something stouter if you ride flatter terrain. I swapped out the Crests for Arches which I've trusted for years between Colorado, Moab and Pacific Northwest riding. They also accommodate slightly wider tires. The seat even fits me! I usually expect to swap seats for my usual but I think I can put some miles on this one.

Rocker

The bike is great. Very smooth, quite, and super fast on the trail. On flat blacktop you quickly meet your maximum speed but this isn't what the bike is designed for.
