Re:
That's a proper dilemma mate... Even factoring in the random chaos of Orange circa 1989-1992 it still is something of an anomily that doesn't compute.
I'm pretty certain my first CW was '92 - it had been ridden and raced througout winter before I brought it in uni finals summer. I'm about 95% sure it was MD set as the ratios look right from memory - but the chainring decals had departed or been peeled off by the time I got the bike which doesn't help. SO.. there is a very remote possiblity it could have even been the "powerflo" chainset that preceeded it :|
Makes me wonder what came first, product or catalogue? with the benefit of google now MD definitely doesn't appear till '93 but I'm quite suspicious that MD might have been available to builders before it got into the '93 catalogue. Is that possible?
