Free hub body

[twentysix by twentyfive]

Since spacer 6 is very close at 1.2mm, have you tried it in place of the 3.75mm one while ensuring good fit and no clash between freehub and seal/dustcap? I am asking also because if you did get the M565 LX freehub from that Bikeradar/crc link its freehub seal/dustcap system as standard is different to that of your 5500.

If the 1.2mm spacer works you should use it - allowable error and therefore choice of replacement is much greater for replacing 6 (and indeed 5 the locknut) to achieve suitable locknut position.

That's a great plan as I may not need to go on a spacer hunt. As for the 0.05 mm - it's quite possible that's the sort of error size in my measurements anyway. Deciding exactly where on the bearing surface to measure is difficult so I used a nearby "ledge" which I hoped would be the same distance from the appropriate bit of the bearing surface in both freehubs. Although I think I may need to loose that 2.5 mm from the axle stack length on the drive side anyway - to retain the 130 mm OLN. Does that latter bit make sense? Or will the frame flex enough?

I've been a bit distracted with sorting my bike out (and my Mrs's bike) for a Tour up the West Coast very soon now so haven't had a proper play yet. I'll report back after my Tour - probably in early June by the time I can have a go on this.

Chance is you have already lost the 2.5mm introduced by the new freehub by replacing the 3.75mm with the 1.2mm, so you just need to find another ~1.2mm spacer.

Yep - that was my thinking too

Crumbs. I clean forgot to sort that freehub issue out after having a super season's riding. I've been riding that robbed freehub all winter and it packed in yesterday. So I was forced to re-address the problem.

I removed the 3.75 mm spacer and put the 1.2 mm one in its place. Scouted through my bits and bobs and came up with a crinkly type washer that was about the correct 1.2 mm thickness. I reasoned that clamping it tightly would squash the smallish crinkles. I offered the completed set up to the rear drop outs and you would never have guessed anything had been changed. Now I need to repeat the exercise on the spare wheel so I'm off the buy another "incompatible" freehub.

Thanks for your help @RecordAceFromNew
