Rolf Prima uses the Stans NoTubes BST technology so these wheels are built for tubeless and tubeless ready tires. Each wheelset is shipped with tape and tubeless valves. We very quickly used these wheels as tubeless with Hutchinson tires and had no issues whatsoever.
Outer diameter is 24.5 mm and 21.5 mm on the inner diameter. These are not wide by today’s standard but they are sufficient for XC all the way to light All Mountain duty.
We mounted these up tubeless on or beloved Norco Sight 27.5 bike and got on with the riding. It looked a little odd at first having such big gaps in the spoke pattern on a mountain bike but there was not really an issue with it. Debris can get caught in the spokes more easily but it was never an issue for us.
The wheels were smooth from day one as the bearings were free spinning with minimal binding. The ratchet mechanism felt precise like a Swiss watch and it just worked without any ‘popping’ noises whatsoever. When freewheeling, the wheels were loud but not obnoxious like some that we’ve tried. We’d say that it’s in the 65% perecentile in noise level compared other mountain wheels we’ve tried.
So we just used this wheel everyday on every kind of trail and they just performed. Compared to a couple other wheelsets that cost more than twice as much, we could never really tell the difference. The others may have been 100 grams lighter and better for 200+ lb. riders, but for this 150 lb. tester, the Rolf wheelset seemed ideal.
So for $900, Rolf Prima delivers a fine wheelset with the Ralos. They’ve only been doing mountain bike wheels for three years, but we believe that they will gain many more fans as mountain bikers get to try their wheels.
