"Where have Coefficient bars been for the last 15 years? So many beneficial hand placement options. Those notches on the drops are so practical. Endless Gains..."

"The Coefficient AR's shape encourages external shoulder rotation – a superior position for core & thoracic stability, breathing mechanics, nervous system function & grip strength."

"...I quickly noticed a big change when riding in the drops along a stony towpath. This bar has the most effective vibration isolation of any that I've used..."


"After 3 months, I still appreciate how much better it rides. Every. Single. Ride. I used to spend 80% of my time on the hoods, now it’s like 50% on the tops and 40% on the hoods. Narrow is aero, and the Coefficient bars pocket my elbows naturally at my sides, not like chicken wings in the wind.”

“I love the Coefficient bar! The slope and sweep really allows the wrists and shoulders to sit more naturally. This, in turn, is improving my breathing and position on the bike..”

"Good feel when pulling on them when climbing seated; for sure less 'deadness' felt in arms/shoulders; great extra comfort when on the tops.”

"I have been amazed by how good the tops feel! The thumb notch in the drops is also a game-changer in sprints and on dirt descents. You are definitely on to something really good here!"

“I have been riding the Coefficient AR for the last 3 months and just purchased two more! Ergonomically, Coefficient is the most comfortable drop-bar shape I have ever ridden.”

"I'm not going back to "normal" bars. Everything is right about the Coefficient bars."
