view the comparison chart

Turbo Highlights | Classic Highlights | Descender Highlights

All 3 models are available with your choice of lengths, and drop.

Why Lower?

• Want to descend faster and with more control?   Lower your seat. You will feel an immediate change in the way your bike handles.
• Lowering your center of gravity (GravityDropper™) means better balance, more control,and more confidence, which gives you the ability to go faster !!
• Ride sections you have only walked before!
• Maintain speed in sections you’ve had to back off a little before!
• Extra safety on downhill and technical sections!! Less Crashes

Why Raise?

• Most efficient position for climbing and level terrain.
• To deliver maximum power to the pedals, you must have your seat in a raised position. Many bikers compromise their seat height for more technical riding.   With GravityDropper™, there is no compromise. Seat High for power and climbing. Seat low for descending.
• Takes a fraction of a second to raise or lower your seat.
