Reserve uses internally reinforced spoke holes to strengthen the area where the rim sees the most force, around the spoke nipple. This provides for improved strength without adding unnecessary weight.
The 34|37 is designed to be your no fuss climbing wheelset. There are no weight limits, no tire limitations, and can be set up tubeless or with tubes.
The mixed profile front and rear setup of the 34|37 provides for maximum stability, lowest weight and optimized aerodynamics.
