Rider Feedback

The first question everyone has when they look at the SB5.5 is: How does it climb? It’s clear that his thing goes down hill like a beast, but how does it go up? For what it is - it climbs wonderfully. The Switch Infinity provides a ton of traction and bump compliance, while sitting just high enough in the travel to avoid most pedal strikes. Rougher climbs are best approached with compression damping at a minimum, but longer smoother slogs can benefit from a flip of the blue lever. Downhill? Well, you can imagine.. This thing is like a freight train. Once the big wheels get going, they roll anywhere you want to point them. Speed and momentum build quickly, and you’ll go from fast to terrifyingly fast in the blink of an eye. Even with all this potential for speed, the geometry of the 5.5 doesn’t force you to pick the straightest line. It’s quick, nimble, and changes direction surprisingly well. The drawbacks to a bike like this are few, if any and we’ll see more and more riders making the switch to a bike like the 5.5.
