Oval rail, 7 x 10 mm, in a natural charcoal gray color.

They will make any of our seats 100 gms lighter.

They are interchangeable with any of our seats.

Recommended for intermediate to advanced cyclists.

Not recommended for any off road cycling, gravel biking, power assist bikes or extreme MTBing due to the nature of the carbon fiber material.

The Carbon Fiber rail diffuses the G-force shock felt from the surface of the road through the bike that transfers to the cyclist.

While in a high performance mode, delivering a high wattage cadence, you’ll have a decrease loss of energy from side to side and an increase kinetic energy in a forward motion.

For side mount clamp: you’ll need to get a 7x10mm ears and cups for your seatpost.

For top mount clamp: should be fine, but you might need a longer bolt to accommodate the 3mm increase in height of the rail.

Watch video for installing G-Force pads for both side and top mounted seat posts.
