Q-Rings Qarbon

The Qarbon chainring is constructed from a combination of aluminum and carbon fibre. A 3k high modulus carbon fibre is wrapped around a machined aluminium core, with the use of the carbon exterior allowing more metal to be removed, resulting in less weight. The Qarbon is claimed by Rotor to be 8% lighter and 20% stiffer than its regular Rotor chainrings.

Qarbon: the right material in the right spot
Qarbon owns this principle by bonding a 3k woven high modulus carbon fiber sheet to the Q-Ring´s exterior side, allowing for a more aggressively machined aluminum section and increasing lateral stiffness while improving shift quality. The result is an eight percent lighter chainring with 20 percent increased stiffness – and an appearance inline with your bike´s sleek, elegant aesthetics.


Peer-reviewed scientific research has shown that QCARBON/Q-Ring offer a clear increase in performance compared to round chainrings. Elite level cyclists saw a 1,6 sec advantage in a 1KM TT study, generating 27W more power. For comparison, 60mm aero wheels often claim 1,5-1,8 sec/km and 16W savings.

What does this mean when you’re riding? You will discover increased endurance, realize explosive sprints and see a newfound tenacity in climbs. You will find that you can stick with the hardcore group that usually drops you. You will become an improved version of yourself, ready to set new PR’s and discover a new depth of performance. Triathletes will notice reduced strain in the bike split and better run split performance.
