H+Son SL42 rim
Like the H+Son Formation Face, the SL42 owes its stiffness and aerodynamics to 42mm profile height.
The two models share the same lightness, reduced to around 615g using the G609 aluminum alloy which is also 30% stronger than the 6061 aluminum alloy typically used in rim manufacture but - unlike the Formation Face - it is ok to use a brake on the SL42.
