Ive just come to take the cassette off my pro 2 evo hub and instead of coming off the free hub it has actually pulled the free hub off the hub body.

When I finally got the free hub off the cassette I came across this gouging on the free hub body ??

Is it normal or do I need to replace it ??

Also one of the pawls on the free hub wasn’t as springy as the other three and the spring underneath it moved around a lot? I take it the spring is done for?

If so am I ok just replacing one spring or am I better off replacing all four?

Thanks

Steve

Gouging is normal. Smooth the worst off with a file. The pawl springs come as a set so you might as well do them all. Newer springs are supposed to be a bit more durable than the original design.

Hub on a hob – you are Dr Seuss and I claim my £5.
P.s. What he said^^

And this month’s “picture of a Pro 2 freehub that the cassette has eaten in to” award goes to Renton!

This has been happening to my Pro 2 hubs since my first set in 2006. I’ve replaced the pawl springs every so often and filed off the worst of the gouges. I’ve continued to use them and the universe is yet to implode so I think you’ll be fine 😀

Cool !

Ive never seen it before on any other hub so found it a bit weird!

It happens to lots of alloy freehubs but I guess there’s a lot of hope hub users hear. American classic reinforce one of the splines with a little strip of steel. However, I think they got a patent on this so no one else can use the same trick. I’ve also read that you can straighten out a carpenters staple and push that into the gap for the same effect.

Sounds like a euphemism…….fnrr fnrr

Newer novatec have a spline I think.

Apparently you can reduce but not stop hope gouging by tightening up cassette ring bastid tight. Anyone else heard this?
