New roadbike. Poor cassette quality control? I've just bought a new ROSE PRO SL 105 roadbike and took it for a spin. At first, i noticed a little clicking sound in the rear cassette. I thought that it only might need some time for the chain to sit properly. When I took a closer look at the cassette, I've noticed that some of the teeth look a little too sharp, unlike the others.



Is this something I should be worried of? It seems to me like a failure of the quality control. The rear cassette is a Shimano 105 CS-5800 11-speed.

If so, I will contact the support for the warranty claim. Do you have any experience how they will approach this problem? Rose is a manufacturer and also a direct bike seller like Canyon, so they have no retail stores.

Thanks in advance!
There does not appear to be anything wrong with the cassette. Shimano helpfully put some nice clear pictures of individual sprockets on the product page for the CS-58000 cassette.

You can easily see that the smaller sprockets have some 'chisel' shaped teeth.

Clicking at the rear derailleur usually indicates slightly miss-adjusted indexing which is quite plausible on a new bike. Check for that first.
