NAHBS 2019: Rotor 1x 13-Speed Hydraulic Groupset

NAHBS – North American Handmade Bicycle Show – Held in Sacramento, California from March 15 to 17, 2019, the show features builders from North America and beyond. The mission of the first annual NAHBS and every show thereafter is a simple one, showcase the talents and ideas among the best builders of handmade bicycles in the world.

But, the show isn’t all about beautiful bikes. Groupsets and components also make an appearance, and in this instance, it is Rotor’s unique, groundbreaking groupset that goes beyond 12-speed, all the way up to 13! The groupset is simply named 1×13.

What makes Rotor’s 13-speed groupset (also capable of 12-speed) is its hydraulic actuation. No cables, no electronics, just a single and tiny hydraulic line to shift the rear derailleur. Rotor feels there is too much gear overlap with conventional 2 x 11 groupsets, and 1 x 13 is their take on the solution to near perfect gearing for road, gravel and later on, mountain bikes.

Lori of Rotor Bike Components walked me through the system, which includes a brief demonstration of the rear derailleur in action.
