RSV 40|44 Wheelset
Set of Reserve 50 carbon wheels

Reserve 40|44

When we began development on the new Reserve 40|44, we were looking to create a wheelset that provides all-day capability with aerodynamic sensibilities. The 40|44 features a wider, shallower front mixed with a narrower, taller rear wheel, which has proven on the tarmac and in the wind tunnel to deliver speed with the benefit of stability. And it’s designed to provide a comfortable ride all day long. Hit a rough patch of road, no problem! Dart down a gravel-strewn alley to short cut your way to the coffee shop, zero issues. The 40|44 delivers just the note of forgiveness when you need it, to let you keep racking up the miles when others are already legs up on the couch.
