Spoke protector for 40 hole rim and large hub flange?
Does anyone know if a plastic spoke protector is available for a 40 hole rim and large flange hub? I googled and could not come up with anything. If a 40 is not available do you know if a spoke protector made for a different hole count would work? Or possibly something homemade? Any ideas would be appreciated. I know a lot of folks do not use one but I like the idea of it just in case.
We have a Burley Duet from I think 2003. It is a nine speed. Not that this is relevant.
Thanks!

Thanks Rick, I did take a look but saw nothing specifically for 40 hole hub. So many spoke protectors listed on various websites fail to provide detailed info. I think I will keep my eyes open for a suitable piece of plastic and make one up.

If you rear derailleur i properly adjusted it's not needed. I haven't used one since I had a 10 speed bike over 40 yrs ago

Haven't put a chain on the inside in 45 years of riding derailleur bikes. I adjust the inner limit screw. Even downhill bikes don't use those plastic discs.
OTOH on our last tandem ride I had the chain come off on the outside and jam between the 11 cog and the frame. Never had that happen before. We were coasting really fast on a street with some big bumps and I think the slack chain just jumped up and over. Don't think that happens on the inside because the chain is tighter and one is moving much more slowly with the chain on the big cog. Can't offhand think of an easy way to prevent that outside jam either. On the 3rd hand it only took one minute to put it back where it belonged.

I didnt think these things cared how many spokes are in the wheel but then, I dont use them. I take them off, not put them on but have never noticed anything about them that would suggest spoke count is relevant.

The spoke protectors I have encountered have little tabs that clip to the hub flange. The clips fit in the space between the spokes. I think different spoke counts would make it necessary the clips being spaced to fit.

Cassette hub ?they are made with 3 or 4 molded in hooks ..
might need lightening holes in the flange so the ones for small flange hubs work
(others went on first then freewheel screws on next)
Winging a bodge..
Seems possible to use a freewheel spoke protector on a freehub driver diameters are close ..
or modify one with little zip ties , to the spokes .. (or the biggest cog holes)
Yes wiping out the rear wheel , and rear derailleur in a moment is no fun.
I put one on my touring bike so I would not face a long walk..

Update: Could not find a spoke protector intended for my spoke count. I ended up installing a spoke protector that fit the hub diameter. I cut the plastic clips off as the spoke protector was designed for a wheel with less spokes. Secured protector by strategically drilling holes in protector and securing with nylon cable ties.
