Aluminium bolt to hub spacers

[banderson]

Just wondering how safe they are really?
i know a lot of people have the ones from dan at M.a.d (me included) but the thought that the wheel is bolted to aluminium whilst that's bolted to the hub?

anyone had any issues?

No, not even the track boys.

Only problem I can forsee is stretching the threads by over tightening the wheel bolts.

I will only use spacers with a chamfered bolt for bolting to hub and steel inserts for bolting the wheel to. Threads are massive stress raisers as are counter bored cap heads. I know in the scheme of things they are massively over engineered but I'm paranoid and believe in good engineering principles.
