Titanium Nitrid bosses... again

[TrevorKershaw]

I bought some Titanium Nitrid bosses for my Pace RC35’s but as mentioned in a previous thread, they don’t fit as the threaded section is too short, see picture below.
L to R:
33/34mm Boss from Rear of E3 frame
New 34mm Ti-Ni boss.
Long 38mm boss from RC35's

That’s the bad news. The good news is that they fit the rear of my E3 beautifully.

Question:
Does anyone know where I would find M10 Titanium Nitrid bosses that are 38mm long?
The only ones I could find on Ebay came from Teipei (and very quickly, I might add), but they are only 34mm.

Also, due to the rear ones being fitted to an Alu frame, would I need to use copper ease to prevent siezing, or would the Ti-Ni coating prevent this?

Your thoughts please?

Use the 34mm's on the rear with copper-cote, the standard threading won't be a problem on the rear as the braking force is pushing not pulling as when on the aluminium fork. Stainless studs/bosses are available, however not sure in the longer length threading. The canti studs thread length on my Answer 1 fork is 34mm as well and, I never had a problem with them. Always use copper slip on all dissimilar threaded connections!

As the brakes are on the back of RC35's the same principle applies as brakes on the rear of a frame.

Thanks for the opinions folks. Sounds like they should be okay. I always use copperease anti-seize with differing metals, just in case.
