Brand new Mk4 version of the legendary fast and tough mountain bike wheelset for XC/trail and recreational use. 29er size only at the moment. 

Rims are the brand new Mk 4 Stans Arch made from aluminium alloy. Wider and stronger and even slightly lighter than the Stans Arch Mk3 rim with a 28mm internal width. The spoke drilling is offset by 2.5m which improves wheel strength.

Disc brake specific. Designed for tyre widths between 2.25 and 2.50. (for tyres between 2.35 and 2,6 also consider the slightly wider Stans Flow Mk4 rim - see our other listing). New discreet graphics.

These rims are designed to be used tubeless (with Stans sealant) but can also be use with Presta valve tubes.
