Bill Talbot posed the Q, and included the Suntour Winner FW.
"durable, great cog selection, resonable priced too!" ++++++++++++++++++++++++++
It may have been really unusual, but my memories of L'EROICA last year will always include the two stops to tighten my Winner's bearings. Somehow, although I'd road-tested the bike, the (narrow 6) wasn't quite right. Unlike lesser designs that use shims to set the cone spacing, the Winner has a lock nut. Not easy to adjust and set in the field, if all you have is a rock, a swiss army knife, and a small allen key.
On the other hand, as Bill says, the Winner (and the lower line "Perfect") set a standard for value and fantastic availability of cogs. And darned easy to work on.
