[Closed] Centrelock + Boost adaptor - a step too far?

I'm trying to use non-boost centrelock wheels on a boost fork.

No native boost endcaps for the wheels so I'll need to use those boost adaptors on ebay - which take 6 bolt discs.

Adaptor upon a adaptor - I'm a little worried that its a step too far. Would you?

How about just putting both axle spacers on the non disc side and redish the wheel? No adaptor needed for disc then.

I can't see adapter on adapter working to be honest, as the lock ring sits outside of the disc bolt holes. Adding a 5mm spacer would mean you would have hardly any threads of the lock ring engaged.
As above, I'd go with both spacers on non-disc side and a re-dish.

I use one of these and re-dished the wheel as recommended by someone on here. Tidied it up and gave it a polish, works a treat for a couple of quid

Sorry to be thick here but what your saying is
1) get a 10mm spacer toake it 110mm in total
2) get a wheel builder to reddish the wheel which will put the rim back into the middle of the fork but leave the disc roter in the right position for the caliper.

Does redishing require different length spokes?

I use that £2 spacer linked to above on the driveside, then redished the wheel. I wrapped the spacer and the end of the axle with black duck tape. You'd never know it was there.

You can keep using your centrelock disc and even if you are not mechanically savvy redishing a wheel is very easy- loosen one spoke half a turn, then tighten the next one half a turn. Repeat until the wheel is in the right place.

yep exactly that. Spacer on the non-disc side so the disc and caliper stay where they are.

The rim only needs to come across 5mm, you can do that yourself. Add 1/4 turn on each spoke, non-disc size, and check. Maybe worth giving it a quick, 10-15m ride to loosen any twisted
spokes on each rotation, you will here them pinging into place. If they get tight release 1/8-1/4 of a turn on the disc side and put it back on the non-disc side. A decent spoke key and a bit of a turn each time, same on each spoke to avoid any flat spots. You may lose a bit of true but you'll get the feeling of the way the rim moves when you do it.

Hope that makes sense, give it a go, what's the worst that can happen...

edit - did you post about that spacer on here Munrobiker? If so thanks for the tip

It's worth loosening the disc side spokes 1/4 turn before tightening the drive side.

Thanks - I'm not usually brave enough to touch spokes in fear that all my teeth will fall out. But this seams do-able.
