Rockshox Judy and SID hybrid

[d8mok]

In theory would a 98 SID crown and stanctions fit with a Judy lower leg /internals? Or even a SID lower leg but converted to Type 3 internals?

Yes, I believe so.

You probably have to convert the M6 bolts on the lower legs to the M8 bolts the SID uses like @Thias did on his Hydracoil conversion:

I had the same idea a few months back and have all parts here but in the end decided against it.

I also tried the Hydracoil conversion: it works great but from all the oil the fork gets a lot heavier.

If you do it, please show your progress. Would be interesting for future projects!

there are hacks where just a Judy crown, the one with screws from early years, is used on early SID models till 2002.

You have to carefully cut the original fixed/pressed crown from the stanchions of the SiD.

With that you can also build than a SID with 1" steerer, which was never on sale.

Whats your intention or idea?

I’m wanting to build a spring converted Judy but with a Sid crown

Or a spring converted Sid is fine too. As my intention is to have it painted a custom colour

I wish I'd thought of this 3 weeks ago before I sold a manky rotten Sid that worked fine and a yellow non-corroding Judy with no internals. It never even crossed my mind.
