Brake disc spacers

rockmonkeysc

My front disc seems to need spacing out from the hub. Bolted direct to the hub it is out of line with the caliper by approx 5mm & the back of the caliper would clash with the spokes.
Its an Intense hub & Juicy seven brakes fixed to RS Domain forks with post mount fixings.

Pictures? That just shouldn't happen!

try adjusting the caliper on the post mounts.

also on some smaller disc sizes caliper contact with spokes can happen with some wheel builds.

More info on the specs and pics.

Will take a photo this evening. Disc diameter is 203 & it's too far out to adjust the post mounts.
There are no markings on the hub other than Intense, it's 20mm bolt thru. Wheels are from ebay so not sure of exact spec or original brake set up. They don't look too old, It says MAG 30 DH on the rim.

are some drawing for hubs etc. so you can check the specs.

is thius 5 mm radially - then you need different post adapters - or tangentaially - would need to see photo asd they cannot be unless your forks (or calipers) have unusual mount.

The 15mm dimension in this drawing measures 20mm on my hub, so the disc is 5mm too far in from the fork leg. Is it possible to get a 5mm spacer & longer bolts or a disc with offset mounting?

Is it possible the hub is similar to old Halo hubs? They had offset bearings and required a slightly larger 20mm spacer on one side. Does the wheel sit equally in the forks?

lets have pics please.

also the spacers could be the wrong way round.

quite a few makers did this Hope Bulbs common confused people.

I have some pics.


These are the only markings on the hub


Wheel in the forks




Back of the caliper (Avid Juicy Seven) clashes with spokes.

Is the wheel dished so it's in the middle of the stays?

The rim does seem to be central between the fork legs, hard to measure accurately but within 1-2mm

I had a similar problem when I first converted to disks from V brakes. I had Hope Sports hubs, turns out I needed to change various spacers and i think the axle as well.

Check for loose spokes.

nicklouse

it could be that the hub was done for a Intense special.

LBS time really to see what is going on.

Hope used to do some 2,5mm rotor spacers.

But I think is is something different.
