Belt drive conversion…

Cool, thanks. Was thinking of something with a 39t front. Think I want just under 2:1 so 20t, 21t, 22t rear. Haven’t put hose numbers and cs length into the gates calculator yet to see if there. Is a suitable belt.

Shortest belt is 113T, so with those chainstays, you’ll not get anything near a 2:1 gear with a 39T front.
46:25 with a 113 might just fit. You may need to take a file to the dropouts to push them back a touch more than the limit.
Or you could go 50:25 with a 115T belt for 2:1

I’d like to place the order this week, so let me know….

OK, was being stupid and equating the sprocket size with chain ring size, didn’t want a dinner plate in the front! Realised now the pulleys aren’t as big per tooth. However have decided that for the minute I’m going to stick with the chain setup I already have and leave this as a project for another time. Hopefully you’ll post an update with a comparison of the centre track system to what you have now.

no worries. I was about to email you if you still wanted a setup.
I’ll order mine, watch this space…
