Hi Jamie,
I knew I hadn’t been dreaming, I have stumbled across this...just checking prices to see how competitive you guys are and came across this link
http://www.cyclestore.co.uk/productDetails.asp?productID=3986&categoryID=401
Unfortunately they only have it in a 23” frame and i was after a 19"…
Can see you what your contacts can find?
Another option is where can you buy Track ends as i have an old scandium frame and I have access to welders
