LITEWHEELS Carbon Wheels ENT 2.0 for Canyon Endurance CF6

Hi everyone,

I have this bike: Canyon Endurace CF 6, which comes with a Shimano HG500 11-34 10-speed cassette (10 sprockets).

I'm considering the ENT 2.0 Elitewheels wheelset, which has a SHIMANO 10-11-12S freehub. I contacted the Elitewheels team, and they told me that I would need a spacer to fit my 10-speed cassette.

Does anyone have experience with this? Will using a spacer affect performance or reliability? Any advice would be appreciated!

Thanks!
