Thanks for your response. Here’s what kind of hub is in a Zipp NSW 808
The ZR1 features key technology from Zipp’s Cognition hubs. The seal design is the same as the Cognition, with a large dust cap at the base of the driver body and better bearing seals for more protection. The bearing size also is the same as the Cognition, although the Cognition uses a premium bearing. The six pawls are offset to work in two groups of three pawls. At any time, there are always three pawls engaging. This design creates a quick engagement feel, with 66 points of engagement. The driver body is designed so pawls stay in place for disassembly to make service convenient. Zipp hubs are designed to use J-bend spokes, the most popular type of spokes today. J-Bend, widely available, are easier to replace.
It rained a lot on the bike at Tulsa and my bike was a mess. But you would think when the bike shop checked it the first time it happened they would have cleaned out any grime and for sure the second time when they put on the new cassette.
I will take it to a different bike shop.
