The B.O.R 333 XMD 27,5 Zoll / 650B disc brake rim is likely the lightest 650B disc brake rim with eyelets available and uses the same rim profile as the race-winning 26" version of the 333XMD, designed by B.O.R in collaboration with FRM.
The asymmetric rim profile features an inner width of 19 mm and a welded sleeve joint. The asymmetric profile design offsets the spoke holes by 1,3 mm to minimize the differences in the tension of the left and right spokes. The result is a significantly stronger and more durable wheel. The spoke holes feature eyelets and are approved for a spoke tension of up to 1150 Nm.
The 333 XMD is Tubeless-Ready, meaning it can be used with a traditional tube setup as well as tubeless systems.
Maximum rider weight: This rim is approved for a maximum rider weight of 90 kg, including clothing, shoes and a backpack (if used).
