[Closed] 6 bolt avid rotor fouls diverge frame. Will 6 bolt ice tech fix the problem?

[#9955978]

I just fitted a new 6 bolt disc hub wheel to my diverge using a 160mm avid rotor.  The outside edge of the rotor skims the paint on the inside of the frame which doesn't seem right.

I would have assumed that a center lock hub rotor would be in the same vertical plane as its 6 bolt counterpart?

Will a ice tech 6 bolt rotor move the rotor in board slightly?

The whole of the face of the rotor? It's not just too big a rotor for the frame is it?

In theory all discs will be in the much the same position, there may be a fraction of a mm difference in thickness from brand a to b but if it's as much as half a mm I'd be amazed. Even if it is as much as a that given the inside face doesn't move your gap will be tiny and you're likely likely to find any gap you manage to achieve gets filed with road muck pdq and rubs or vanishes under pedaling loads and rubs.

I'd be looking at the hub as culprit rather than the rotor.

Do you have the right dropout for the wheel you are using? Remember that (some?) Diverges use a different dropout that might affect this.

The other obvious question - is it supposed to run with a 160mm rotor?

What hub/dropout setup do you have?

Everything is exactly the same.  I had a DT Swiss 350 center lock hub in the frame with a 160mm ice tech rotor and the new wheel is a DT Swiss 240 6 bolt hub.   I have used the end caps and 11 speed free hub off the 350 hub as the 240 came with a 10 speed free hub and 142mm * 12mm caps.

It literally has zero clearance and and although it is not stopping the wheel rotating you cannot see any gap,

In which case it seems you have the wrong endcaps.

That was my thought too, are the 350 and 240 end caps definitely interchangeable?

Now I think I have discovered the rookie error.  The hub I have purchased is a 6 bolt version.  This came with 142mm end caps and is listed as a MTB hub.  My existing 350 hub is a center lock road hub.

This explains why when I tried fitting the 11 speed cassette onto the 240 it was too short and I subsequently switched the road free hub off the 350 along with the end caps.

I suspect there is a slight difference between the road DT Swiss hubs and the MTB ones.

Expensive wheel build error.
