Designed to deliver reliable performance across a wide range of drivetrain setups, the Hope 104BCD 4-Bolt Chainring is the ideal upgrade for riders running a traditional spider-mounted crank system.
CNC-machined from durable 7075-T6 aluminium, it features Hope’s latest asymmetric tooth profile, engineered to work seamlessly with 9, 10, 11, and 12-speed drivetrains—including SRAM T-Type and Shimano Hyperglide+ systems. This new design ensures excellent chain retention, smoother running, and better performance at extreme chain angles often encountered on modern 1x setups.
Improved mud shedding capability keeps your drivetrain running cleaner for longer, while the tooth shape allows for greater chain wear before performance is affected—extending service life and reducing maintenance.
Available in 32T, 34T, 36T, and 38T sizes with a 104mm BCD 4-bolt pattern, this chainring combines versatility, strength, and long-lasting performance—ideal for trail, enduro, or bikepacking builds using conventional cranksets.
