If you talk to the excellent folks at SJS they will know, there is a Q&A here but not sure if it helps:
https://www.sjscycles.co.uk/freewheels/sunrace-mfe90-9-speed-freewheel-1132t/

Digging deeper (on SJS own website) it looks like some of the 8 speed freewheels they sell are 39/40mm wide - so I imagine the 9 speeds would be about the same

7 speed is normally the maximum for a freewheel, otherwise you can run into rim offset problems. You need a DNP one too for the 11T top gear. DNP do have some new narrow 9 speed ones, but I don't know anyone selling them.

Thanks for the replies,i think i will need to run a triple on the front to get the range and 7 on the back.I will get onto sjs to confirm

Thanks again Shaun

You won't get a DNP one from SJS. You get them from Aliexpress or some ebike kit retailers.

Might still be worth asking SJS too, they stock DNP kit and know their stuff

They seem to only have the 10 speed on their web site...

7 speed available on Ebay here.
The same seller also sells them as a set with a freewheel tool that will cope with the larger 14mm axles found on some kits.
