Jagwire Pro LR2-E rotors are built to improve the performance of any e-bike. They feature an integrated magnet for use with e-bike speed sensors and also use a similar two-piece design to our LR2 rotors. The stainless steel braking surface provides quiet and consistent braking performance and the lightweight aluminium inner spider features an integrated concentric ring and reinforced riveted joints to resist deformation and increase durability.
