when used in a 16-8, or similar, arrangement ...
Negatives are ...
- Spoke breakage which leads to an unrideable, and usually unrepairable, wheel and perhaps even frame damage
Do you have real life testimonials about this actually happened ? Or you're talking about theory...?
Cause I never read anywhere about somebody being ejected from the bike because of a NDS spoke breakage, either on any Fulcrum wheel, or else...
Hi Louis, Fulcrum use the Campag 14-7 triplet arrangement which is symmetrically better than the 16-8 arrangement. They both work but the Campag design works better, although the spoke tension is an issue with this arrangement. That is, if the spoke tensions are to high the rim can bulge between the triplets, so the stiffness of this design is limited.
Yes, I do have an example. A friend just recently was using the 16-8 design with a 24mm deep alloy rim and a NDS spoke broke. The rim buckled so badly that it jammed against the chain stay and definitely was nolonger rideable. A new rim was required for the rebuild. The frame needed repairing also.
The 16-8 arrangement is still a good approach though, but like all designs it requires optimization to work well
