Is 2mm Too Big A Spoke Length Error?
Just a quick wheelbuilding question, please.
My daughter's bike has Normandy high flange hubs and Mavic MA40 rims. 36 hole, 3 cross. I do not recall what length spokes I used, but spoke calculators say 296.3 mm and I always round down, so likely used 296 mm.
I am toying with the idea of lacing in a generator hub. To keep the cost down I went looking for such a hub with dimensions similar to the Normandy. I came up with the Sanyo H27 which also happens to be among the least expensive genhubs.
According to the spoke calculators I checked, rebuilding this wheel with the Sanyo hub requires 294.1 mm spokes.
I "think" that 2 mm is not much difference and there is a very good chance I can re-build the wheel using the Sanyo hub and the same rim and spokes. What do you think - am I being too "optimistic"?
Dimensions per calculators (I haven't personally checked, yet)
