ROTOR QXL Inner 110mm Road Chainring for Shimano 9000

The QXLs are intended for runners with a predominantly rapid muscle contraction (Fast fibers). These are generally the so-called ?Powerful? runners, with a muscle mass and a peak of power higher than the average (the sprinters for example). For these athletes, greater ovality allows them to reduce negative work compared to our standard ovalization. The QXL is more effective for dancer efforts (sprinting or climbing), as it optimizes peak power as dead spots become more critical.Attention, compatible shimano 9000 110mm center distance Bindings 4 branches Weight checked Alltricks: 92 grs (in 36 teeth)
