We bought 2 sets one for my husband and one for me. They are comfortable to ride with and I cannot recommend them more highly. Love love love them

Rode today my new Quick-Release Clip-on Aerobars great relief on the back and hands.
Oleksandr S.
I chose this system to add resting positions for my hands during long-distance trips, as well as to use during long rides against the wind.
Gunther B.
It's really cool to combine two characters in one bike with just the two positions of the seatpost.
Reinhold S.
For me it’s not just performance, for me it’s more variety in position
Edward D.
The dual-position seatpost works really well and is extremely simple to use. Using it with aero bar extensions & the ability move the saddle slightly forward.
