I’ve got a problem with my 26″ 32 hole Mavic XM 719/Alfine wheel, which is that the spokes keep snapping off at the nipple. I think it is because the Alfine flange diameter is so big that it makes the angle between the spoke and the nipple too acute. So, one solution is to rebuild the wheel in a 2-cross pattern. The issues are:
1. using this website the spoke lengths calculate to be 238mm, which is v. short. Can this be right?!?
2. it is hard to buy spokes at this length for a reasonable price, however Rohloff make some. Are they any good?
