To clarify.
1. Bought small parts kit. Bolt wasn't included and I believe it is not a part of the kit.
2. Didn't buy shifter SL-C6000 since I need to confirm it works with hubs SG-8R36, SG-S501.
In addition, whether it includes bolt. It makes sense to include bolt but it also makes sense to package hub with ALL needed parts!
