* Specifically tuned to be more shock absorbing than the "comfort" seatposts on the market, while still passing our strict internal MTB strength test. * Flex engineered into the light weight carbon tube keeps the rider comfortable over any terrain. * Secure, two-bolt clamp makes for easy micro-adjustments of saddle position, and the head has been redesigned for maximum bolt head accessibility. * Clamp works with all saddle rail types.
