The Alter Cycles MadMax J42 / J43 Chainring is a special 2022 Halloween limited release, bringing Alter’s bold and playful design language into a small-tooth tracklocross chainring. With its hard anodized two-tone finish, this chainring is made to stand out and give your build a sharper, more aggressive character.
As tracklocross continues to grow, more fixed gear riders are taking their bikes beyond clean city roads and into dirt, gravel, and mixed terrain. The MadMax J42 / J43 offers 42T and 43T options, giving riders a lower gear ratio for off-road riding, climbing, and better control at lower speeds.
Made from 7075/T6 CNC aluminum alloy, this chainring balances strength, stiffness, and low weight. The BCD144 specification fits many fixed gear and track cranksets, making it a strong option for tracklocross, single speed, or fixed gear builds with a more distinctive drivetrain setup.
Limited release. Built for riders who want their bike to look different, ride different, and carry a little more attitude.
