I know the new EVO 40t has a different freehub to take 11sp road cassettes but is it possible to machine down the freehub from a Pro2 EVO (pre-40t) to take 11 cogs (shimano 105 not mountain)? The hope website implies that they moved the flange inboard on the EVO 40t to make room for 11sp road cassettes so should I be worried about somehow fouling the spokes with the chain?
If the answer is "yes you can do it and all will be fine" can anyone tell me how much I need to take off or what the final dimensions should be?
Cheers,

IIRC you need to find another 1.1mm.The bigger issue will be the rear mech cage hitting the spokes.

It doesn't look like there's much you could possibly remove.
Also
the main identifying feature is the pocket machined at the bottom to the spline on the 11 speed body

I reckon this on Monday morning would give you a definitive answer
I filed the standard 10sp freehub this weekend to take an 11sp road cassette and it works a treat. Used a file and some callipers to check each bit was the same.
Yes this is easy to do. Just buy the new freehub in the photo above and swap everything else over. I have exactly that setup on my Warbird.
Cheers all.
I thought the new freehub only fitted the 40t hub? That was the impression I got from the hope blog. Or do the pawls still work OK going from 24t to 40t?
They work fine. It's the hub ratchet bit that's different.
EDIT - as long as it's a pro2 Evo it'll work fine. Original Pro2 won't work.
Cool, thanks. It is an EVO, just not a 40t. Did you have any problems with the dérailleur hitting spokes as Rorschach warned? I'm sceptical that 1mm can really make that much difference but hope did redesign the whole hub body to account for it.......
No

Thanks, sadly that is the page that started the confusion over what you are "allowed" to do and what you can actually get away with!
1.85mm is what you need to machine off.
Worst case, get a machining company to mil off the back of the cassette. Top cog will sit slightly closer to wheel but works perfectly in my opinion.
I have an old XC hub and 11 speed cassette. I took out one of the rings and swapped some spacers around, and the 'gap' isn't noticeable and it shifts across the gap just fine. Obviously you only get 10 gears, but can at least use your 11 speed grouspet. The spare slot on the shifter is at the smallest cog, so there's no chance of shifting the mech into the spokes.
Just found this old thread too which seems to say that if you have a 11-28 or bigger cassette the you should be fine......

Time to take the plunge I guess.
Fitted and working fine with a 32t cassette. Plenty of space between the cassette and spokes without a plastic chain catcher thingy. Mech is a bit closer to the spokes than before but there is still a good 5mm clearance and no sudden death on the bouncier pay off the commute.
Cheers all for the advice.
