Will an 11 speed (road) freehub currently on a Hope Pro4 hub, fit on a Hope Pro2 hub – 10 speed?

One pair of wheels is here, the other is 40 miles away. If I have to order something, I plan to do it tonight.

Hoping someone knows the answer (no pun intended!) 😛

Not sure about the freehub fitting from the pro4 to pro 2, but if you have a pro 2 evo 40t hub you can buy a freehub to take an 11 speed road cassette. An alternative would be to drop a ring out the cassette so it’s 10 speed with 11 speed spacing, so would work fine minus an extra sti click.

To answer the op,no it definitely won’t fit. The part of the hub that sits behind the seal with the pawls and bearing in is a larger diameter on the pro 4.

Thanks. :o)

for future reference

Hmm,
There is a bit a leeway on that Hope explanation.
I have an older Mono hub and fitted a 11speed cassette body.
Hope said it may or may not work.
Ran a Ultegra cassette with a 11_28.
I believe a smaller ratio cassette might have problems with chain clashing with spokes.
Hope were selling the 11 speed bodys and quickly withdrew them when people were having problems.
Re released them when they redesigned the hubs to accommodate any cassette.
There are ways!
Doesn’t help the other O.P much but mite be useful to some!
Thanks,
