Boost conversion kit

[Goodbadugly]

Does anybody know the measurements of these spacers?

As far as I can see from google the disc brake spacer is 3mm. The washers 5mm each?

(15x100mm to 15x110 conversion)

on a similar note i bought a boost kit for a set of wheels i have but the rear tyre now rubs against the frame. Any one had experience with this and do the wheels need re-dishing when using a boost kit?

The disk spacer that is 3 mm is for the rear 142 to 148 for the front you will need 5mm as you are moving the disk 5mm inward so it must be the same as the other spacers.

For the rear, definitely, as it only has a spacer on one end, thereby moving the wheel closer to teh drive-side chain & seat stays.

YES you need re-dishing and you will see it says so on the website of EVO fo0tr excample when you order the boostanator since they only supply and space for the left side and the disk the dishing will be out by 3mm

For the rear it's 6mm as there's only a spacer on the non-drive side - the cassette still sits snug up against the chainstay, so the disc has to have the same spacing that the rear hub has. Though, my mate's one is dead on 5mm wide, as I think they use the same spacers for front and back, and as the caliper has elliptical positioning holes, the 1mm difference can be taken up there.

Sorry you are correct. The rear moves over by 6mm so the disk spacer needs to be 6mm. 

 

For the front I would not use the one the OP has a picture off asn it will create more movement, Woolftooth makes a front boostanator that goes on the right and then you dont need to do anything with the disk, just re-dish the wheel

"In response, we have developed the Boostinator. When paired with compatible 15x100mm or 12x142mm hubs, Boostinator kits allow existing wheels to be mounted in Boost-standard frames and forks.  Disc and drivetrain positions are maintained and, thanks to a quick re-dish, spoke bracing angles are improved."

Yeah, except I wouldn't want to dish the wheel, when 2 spacers (one each side) would allow you to get away with exactly the same build as you currently have, and then the spacer for the disc is there as well. As soon as the TA is clamped, there won't be any movement at all.

So 5mm for the washers and 5mm for the disc brake spacer?

I assume you're talking about a front wheel

[Captain Fastbastard Mayhem]

I assume you're talking about a front wheel

yeah. Re-dishing the rear is inescapable.

6mm for the rear washer (142 to 148) and 5 or 6mm for the disc spacer. Disc spacer can be 5 or 6 as the caliper can move inboard by ~1mm due to the mounting holes on the caliper. Spacer on the axle needs to take up the additional slack, or the rear stays will be pinched slightly and you may not be able to get the axle tight enough to restrict play on the rear axle, and therefore MUST be 6mm

I don't want to buy a kit. A 15x100 to 15x110 conversion.

I like fiddling with stuff and I have a metal lathe. I want to make new end caps for my existing wheel. Doing just the right hand cap would force me to redo the dishing. No big deal, but unnecessary if I can do both sides.

Lekker. Then yeah, 2x5mm spacers at ID of 15mm, and a 5mm spacer for the disc with dimensions mirroring the existing disc mount.

The MRP ones don’t need a reddish on the front. Not sure on the back though.
