Sidi AERON MTB Cycling Shoes Black Size 41

The Sidi AERON Black size 41 MTB cycling shoes are designed for riders who demand precision, stability and consistency in cross-country racing and marathon MTB riding. Size 41 offers a compact, secure fit that enhances control during high cadence riding, rapid accelerations and frequent pace changes typical of XC competition.

The ripstop upper with rubber reinforcements protects the foot on rocky and technical sections while maintaining a lightweight, streamlined race profile. Dual NUUN 001C aluminum dials allow fast and accurate adjustment on the move, keeping the fit dialed in without breaking rhythm. The Firmor X internal support system stabilizes the foot during climbs and explosive efforts.

The UNUM Ergo anatomical tongue distributes pressure evenly, reducing hot spots over longer distances. A full carbon X2FC outsole with stiffness index 11 delivers efficient power transfer, while rubber inserts improve grip on steep, loose and slippery terrain. The tool-free adjustable heel cup allows the Sidi AERON Black 41 to be precisely tuned to the rider’s foot for confident, race-ready performance.
