They have a very complete selection of Suntour cogs and bodies.
Does the Ultra 7 really fit in a 126mm spaced frame? I was considering using one with a 126mm SR hub and do not want to respace the frame to 127-128mm.
Speaking of freewheels, it is difficult to find a Regina 6sp in a 12-24, I had to build one from 3 gray 'Corsa' and unfortunately not a golden 'Oro'.
In 1994 a 12-24 Oro was bought at The Third Hand and has since worn out.
The Winner Pro has a 12t only in the 7sp version.
