Running a 10 speed cassette on an alloy freehub on an eBike can lead to premature wear.
5000km and three cassettes later (replacements due to tooth wear) wears the alloy away.
Apparently the hope steel freehub is just as bad. The new replacement is again, gold anodised alloy.
A remedy is to go with a cassette that spreads the load from a single cog across the whole array.
The slx cassette however doesn't do this, the lower 3 cogs each mount separately on the freehub and the entire
drivetrain load is concentrated on a structure that's 1mm wide. Poor engineering IMHO. You can mitigate it by tightening the
cassette up really tight but it'll still wear out prematurely.
New Hope freehub; $130AUD and 2 weeks freight.
Can you guys see the images in my last two posts?
