VOTEDEAN, here is an idea, that may not be as exciting as making hubs...But why don't you think about making stuff like COGS for fixed hubs.

Honestly there are not a tonne of great cog makers. The LEVEL Hubs are amazing (but nobody BUT level makes them). EAI cogs are the nicest standard cogs I have used, but only EAI makes them.

Rather than investing a lot of time, and money on a new Hub, I think the market needs affordable, amazing cogs more than another "hub manufacturer).

Just a thought.

ALSO, maybe you want to make something simple (Like the JETHRO TOOL). This tool is great, with track bolt wrench and beer opener in one...THe only problem is that it is a double sided 14mm wrench. If you made one with a 14mm on one side and 15mm on the other, I know I would (and many others) would buy a bunch from you!

Maybe some nice custom looking chain tugs...
