Spesh pitch pro. Spesh hi-lo flange hub Jobbie
Anyone know if they do adaptors like Hope?

I think you have a Spesh Stout hub? I still use the 20mm one which came on my Pitch 08. Never heard of any adapters..

Think it might well be a stout hub.
I changed the bearings and is got end caps like a pro2 hub.

See if you can find the hub standards, then measure your hub. a 15mm hub is narrower than a 20mm hub, so the conversion will depend on whether the hub design leaves enough room to run narrower end caps or not. Once you know that, you’ll know if there’s any point in trying to find some adaptors. In theory a lot of adaptors might work.
