Shockingly great, in every way!

I've been on tons of single speeds over the past 25 years including carbon ones, and even custom frames setup with the Gates belt drive, but this one blows them all away! The frame is light but very stiff and responsive. If you haven't ridden a belt before, they will surprise you with how quiet and responsive they feel. This frame makes me loves hardtails again, between it's overall quiet and super light weight, and then it reminds you that it descends massively faster than you would expect it to! Built up at just 18.8lbs, it almost feels like cheating, especially with the way it climbs and how you can flick it around. Well-thought out rear slider design, with the break for the belt designed in a way that doesn't detract from looks at all as you can't even tell it's there. Insanely versatile as you can set the same bike up with or without gears, 27.5 or 29, and change any of those combinations as you desire. Even better that it has a threaded BB shell! I wish the rear caliper bolts were a bit easier to access, and the top tube is a touch wide for my small size, but otherwise, I have a really hard time finding anything to nitpick about this bike!

What a Ride!

This Roker SS is pretty amazing the way it performs. So much fun and simple. After a handful of rides it is becoming more and more my go to bike over my full suspension.
