Yeah I this new stuff really get my blood boiling. Back in the 80's you could buy a freewheel, or body and customize it as you saw fit. it wasn't easy to get the spacers and cogs just right but the companies made them and it was possible. Then they went to cassettes, the perfect system to be able to pick your cogs and gearing and then only started selling complete ones, or not sell or make the cog you wanted, or worse they would rivet them together...

Now we make freewheels similar to cassettes and still make it difficult to customize... It would be so easy to make standard body and cogs.....

I know, I know... it isn't the big market share, it isn't racing, it isn't cost efficient. blah.blah.blah.. (pulls out old codger card)
