The H+Son SL42 owes its stiffness and aerodynamics to a 42mm profile depth, without the hefty weight of other equally deep section rims.

Constructed of G609 aluminum which is lighter and stronger than the 6061 alloy typically used in rim manufacturing, the SL42 weighs in at 615g and has a reinforced braking surface and a machined sidewall that is anodized/polished after machining for a clean look on a brakeless track bike.

Black is available in 20h, 24h and 32h, and polished silver is 32h only.
