Burgtec GXP \/ DUB Boost Oval Tray Black Offest 3mm

Researching and testing many prototypes with varying degrees of ovality, Burgtec found that 115% (center to top) was a must!The same flawless chain retention and the same silence as the brand’s round chainrings.Shortening the neutral point at the top and bottom of the power curve allows you to return to the power phase of your crank rotation earlier.This is a big gain, as almost all studies of pedaling performance suggest that a minimum of 80% of your power comes from the downward motion.Mainly because much larger muscle groups are used for this movement.Details: 10/11 and 12 speed compatible GXP / DUB crankset compatible 115 degrees of ovality Completely machined from 7075 aluminum Offest 3mm
