To change wheel standard it is necessary to change the freewheel body: Campagnolo - Shimano - Sram XD. Each component of the body is included: SKF bearings, cassette stop, pawls, springs, seal. This part is machined down for a significant weight save.
When riding tubeless tyres, it is necessary to use a tubeless valve. Due to rim depth, some may be too short and you would not be able to access the push pin to inflate the tyre. You will need a tubeless valve extender in this situation.
