RIRO NX1 MTB Crankset Features and Specifications
The RIRO NX1 MTB Crankset applies Hollowtech 2 integration to merge the spindle and right crank arm into one rigid unit, eliminating the flex points that rob power on steep climbs and technical descents. A 104BCD chainring standard gives you a vast selection of aftermarket rings from narrow-wide single rings to bash-guard setups suited to aggressive trail riding. Both 170mm and 175mm arm lengths are available so you can dial in the fit for your hip width and preferred pedaling style. The included bottom bracket simplifies installation and ensures the bearing preload is set correctly from day one.

I really liked it, excellent product.

This is a very nice quality crank set. The bearing looks like precision instrument dials on my bottom tube and the crank itself is very light but solid. I had no difficulty assembling the crank and bottom bracket, although the threaded holes for the chainring had to be chamfered slightly. Otherwise, a really nice piece for a great price. I’m using this with a single chainring on a retro road bike. Highly recommend.
