Jagwire Pro LR2-E Disc Brake Rotor

The integrated magnet is specifically designed to work with e-bike speed sensors. If your current e-bike setup relies on a rotor-mounted magnet to track your speed, this rotor ensures that functionality remains intact after an upgrade.

While it will physically bolt onto many hubs, it is specifically engineered for the heavier weight and higher speeds of e-bikes. If you are riding a standard mountain bike, you may find better options in Jagwire’s non-e-bike specific rotor lineup.

No, the Jagwire Pro LR2-E does not include a lockring. You will need to reuse your existing lockring or purchase a new one separately that is compatible with your specific hub setup.

E-bikes are generally heavier and travel at higher average speeds than traditional bicycles, which generates more heat and requires more stopping force. The 203mm diameter provides increased leverage and surface area, resulting in more consistent, powerful braking performance.

This rotor is optimized for hydraulic disc brake systems. While it may physically fit, the braking surface and material composition are designed to handle the heat and modulation characteristics of hydraulic systems, so performance may vary with mechanical calipers.
