QR15 thru axle

QR15 thru axle

The "15" stands for the axle diameter, the "QR" for "Quick Release" – and together for the most functional method of anchoring the front wheel in the (suspension) fork. The advantages are impressive: high rigidity, precise brake disc positioning and foolproof operation. STEVENS therefore equips all mountain bikes and E-MTBs as well as the highest quality trekking bikes, cross bikes and E-bikes with them. For (E-)MTBs in particular, the installation width has even been increased – from 100 to 110 mm, which is even stiffer.

E-thru rear axle

E-thru rear axle

This abbreviation stands for Shimano’s thru-axle standard for rear triangles, in which the threaded nut is integrated directly into the dropout. The 12 mm axle ensures outstanding rear triangle stiffness and absolutely precise positioning of the brake disc – this avoids annoying grinding noises.
