Hey guys, so after just maybe 500 mi or so of riding on my new Powertap SL, I tried to change the cassette, and to my dismay found that the cassette was lodged on the freehub body. I was able to use the chain whip to rock it free, but what happened is 4 or 5 of the cogs (in the middle gears - Ultegra 10 sp) had dug, clockwise, into the raised portion of the grooves on the freehub body, leaving dents and pushing up the metal a bit. I've since changed the cassette a few times, and everything works fine, but the cassette can still get jammed on. Will continuing to use it like this cause problems, and did I do anything wrong to cause this in the first place?

The aluminum freehub bodies are only supposed to last one race. If you want yours to last longer get a steel one and dont worry about the extra 15 gms.

Switch to Campy or get some American Classic Cassette clips.

Yep, AL freehub bodies suck for everything but weight. Looking online, I don't see any options available for a Powertap freehub body -- just a $60 replacement. I think they're all aluminum.

It sounds like the AC clips are the way to go. A quick search didn't turn up any place to buy them, but you can read about them here, then ask your LBS to get some for you: (Search page for "clips") https://www.amclassic.com/faq.html

As waterrockets wrote, American Classic sells clips for Ultegra/Dura-Ace or pins for 105. I asked about ordering an extra set to have as spares, but they're $15 for the three, so I decided to hold off You can reach them at 800-813-5545. Even with the clips, my 420's freehub body gets some wear indentations from the smallest cogs, but it's in a lot better shape than it would be if the load from the middle four cogs weren't being spread across the width of the clips.

Digging up old threads...but has anyone used the clips mentioned here? Do they work?
