Rear Hub (Freehub) Maintenance Notes
Grease lubricates the parts that rub against each other in the freehub mechanism of the rear hub, helping to reduce friction and wear. Removing all the grease solely to obtain a louder sound is not recommended. Without adequate lubrication, components may wear out or become damaged more quickly, shortening their service life. Use the type and amount of lubricant recommended for product maintenance.
Hydraulic Disc Brake
Yes, the Hyper SLR D25 with the HR-500 hub supports hydraulic disc brakes. Use a compatible Centerlock rotor and match the rotor diameter to the frame, fork, and caliper.
