Due to a lack of research when ordering my new belt drive frame and stuff, I need an adapter to fit the sprocket to my Rohloff hub.
Nicolai use to list all the Gates stuff on their website, including the adapter, and I think I assumed it came with the sprocket when I ordered everything from Qoroz. It turns out it doesn’t.
I’ve been in touch with MSG Bikes, who sell belt drive Rohloff bikes, and Rohloff will only supply an adapter if they fit it themselves.
I would need to post my wheel to MSG, they would then post it to Rohloff in Germany so that they can spend 30 seconds screwing the adapter on, then post it back to MSG to post it to me.
MSG reckon this would cost around £100 all in.
If I get one for my spare wheel as well, that’s £200.
This is what the pulley and a 13t and 16t Rohloff sprocket look like.
What I was thinking was machine the teeth off an old Rohloff sprocket, weld or otherwise attach a larger lump of steel around it, then cut a 46mm thread in that. I’ll sort out all the dimensions and chain line first.
So, has anyone here got the ability to do that ?
How much to make a pair of them ?
Oh yeah, I should have said near to Kidderminster, Worcestershire as I like to deal with people in person for odd jobs like this and I think it would be best to give them the hub and pulley as patterns, but thanks anyway, TJ.
Thanks for that link. I’ve emailed cyclemonkey to see if they can simply supply two adapters.
Yes, I thought a one piece design would be better, but with my limited knowledge of engineering, I thought internal threads were a lot harder to cut, and as I’ve got a couple of old sprockets, I thought a fabricated design might work out cheaper.
