On a trainer, your rear axle sits higher than usual, which can tilt your bike forward. A riser block raises the front wheel to level the bike.
Why level your bike?
A level bike gives a more neutral riding position and helps reduce the forward pressure on your pelvis and lower back during longer sessions.
Three JetBlack options
Riser Block
The Riser Block is fixed. Its deep groove holds road and MTB tires and keeps the front wheel stable. It is the simple, affordable choice.
Turn Riser Block
The Turn Riser Block raises the wheel 3 cm and lets the handlebars turn 20° to each side, so your upper body stays more relaxed. No assembly is required.
Smart Turn Riser Block
The Smart Turn Riser Block adds Bluetooth steering for Zwift and MyWhoosh. Turn your handlebars to steer your avatar and choose your line.
