You`ve got it now Nick. But, hubs are hubs. Rims and wheels are a separate deal. The proper name for what I need is "hub" - not to be confused with a rim or a wheel. Any search for a "hub" will illustrate what I need - only I want it in plastic. Steel hubs are heavy, made of metal and have metal bearings. Even a cheap metal hub is made to support many, many hundreds of pounds more than a set of catrax requires - not to mention the corrosion factor.




Flatlander,

You are correct about the hubs regarding the speed issue. However, I already have some nice wheels (which I want to use) and what I need is a 4-bolt hub to attach my wheels (with 4-bolt rims) to an appropriate axle. I do not believe your design will allow a 4-bolt rim to be secured to an axle. Plus, it all sounds a little heavier than necessary. I will be using aluminum for my axle.
