I check ebay every now and then, but is there a kluge fix or a substitution for the top cog of a Dura-ace Uniglide? The NOS cassettes go for almost a hundred bucks!!!
For the curious, 600 top cogs don't fit because they made the threads smaller on a Dura-ace so you could use an 11 or 12 tooth top cog. So please don't suggest I have a 600 top cog polished and engraved with a Dura-ace logo, it won't cut it!
