The H Plus Son SL42 rim is the original 42mm high rim that took over a year to develop. The SL42 owes its stiffness, strength and aerodynamics to its height and width, manufactured using G609 aluminium alloy which is also 30 percent stronger than the 6061 aluminium alloy used in standard rim manufacture.
If you’re looking for a deep section, robust yet aerodynamic alloy road bike rim for fast racing use, the SL42 rim will instantly give you the performance advantage you want. 19.5mm wide and 42mm deep, it’s the perfect addition to your modern racing machine.
Max tyre size 700 x 32 and clincher only, machined side wall. ERD 557.
