Afterburner’s state of the art aluminium construction is now available in a single ring version. Alloy arms are cold forged for strength yet hollow for lightness. The large cross-section of the crankarms guarantees excellent pedalling stiffness, further enhanced by the three-arm 386 spider. CNC machined from hard-wearing 7050 aluminium, the single chainring is designed for use with the latest generation of 11 speed transmissions and is optimised for maximum chain retention. Choose from BB30 or MegaExo variants. A combination of sandblasted and polished anodised finishes gives the Afterburner an appropriately high-end look.
