They could probably tell you if the conversion is possible.
I own two recumbent bikes that use USS. The "stick" mentioned above is a tie rod. It attaches to a ball on the front fork and another at the USS. Getting parts might mean buying both the handlebar assembly, the tie rod, and a new front fork, Even if available, this would be expensive.
Thanks Vegas Triker, I didn't expect a fast answer on such an old thread !
I know there's no "official" conversion kit from Challenge, as the frame was different for USS and OSS. But before making my own clamp (described as "
a kit from Radius. They use a broad metal-ring of aluminium attached around the frame to support the whole steering system"), handlebar support, tie rod, fork adaptation, I want to check if a "ready made" solution is available somewhere in the World 😉 That's the reason why I was interested in knowing more about the Radius kit...
