Rotor Qarbon Q-Ring Shimano 4 Bolt Aero Chainring 110BCD
Designed to help cyclists to maximise power output in the war against wind resistance, the Rotor Qarbon Q-Ring Shimano 4 Bolt Aero Chainring 110BCD provides a new approach to cycling efficiency.
Providing a subtle 10% ovality, this chainring allows you to take full advantage of the technology that’s been injected from the Rotor brand. Cutting down the dead spot and increasing your power zone allows you to ride smoother, faster and more efficiently. It also reduces the likelihood of injuries due to eliminating strain through your weaker muscles.
Five optimum chainring positions offer precision fine tuning of the chainring, meaning you can fully adjust where your power zones are according to your body, not the product.
The Computer Numerical Control (CNC) machining provides a precise and consistent manufacturing process, meaning there’s flawless functionality at every level of the construction of the chainring. Not only this, but the aluminium 7075-T6 construction is aeronautic-grade, which means you get superior properties such as stiffness and durability without breaking the bank.
CNC machining is further reinforced with a High Module Carbon 3K finish, which reduces the overall weight by 8% and increasing stiffness by 20%. This construction also reduces the weight of the chainring, keeping it to an impressive 133g.
There’s also no reason to swap out your Shimano cranks to accommodate the Qarbon Q-Ring, meaning you can do all the maintenance yourself!
