- The hubs have the advantage that a broken rear spoke can be replaced
- with the sprockets in place. On the other hand this may become more
- necessary than with conventional hubs because the entire spoke load
- must be carried by the weakest part of the spoke. The only part of
- the spoke where the grain structure is not in line and oriented is
- the head because it is formed by smashing the end of the spoke like
- a rivet. Previously the head performed only a retaining function
- while the elbow carried the load. With straight spokes, I would
- expect a greater susceptibility to heads popping off.
-
- Besides, you won't find suitable spokes widely available but if you
- aren't going on long tours, this is not a problem. I think the hubs
- are an interesting novelty with one advantage. Don't worry about
- torque, it is not a governing factor in spoke life, otherwise, the
- large flange hub would be widely used.
