Chroming rear hub

Postby Bobblybob » Sun Jun 22, 2025 3:49 pm

Having had to look to purchase a new rear hub after stripping the splines on my old one, (brakes started binding with heat and torque stripped the splines), I think I’ve decided on a new uni one. However, I can’t find one to purchase that is already fully chromed . Having had bad experiences with beedspeed in the past, can anyone recommend either A) a good source of a pre-chromed uni hub or B) good company that that can chrome my new one. Thanks.

AF have them listed.

Likely it will be indian chrome

Consider the chrome powdercoat??

Chrome on alloy that is heating and cooling never works out well

Thanks Gaz. My old one was chromed in the normal manner and never really had any problems. Had a look on the AF website but couldn’t find any as says out of stock . Also never thought of chrome powder coat. Thanks

Quality chrome had them in stock or as gaz says powder coat. I've had chrome peel off hubs before

Whatever decision is made - chrome, powder coat, foil wrap etc - bear in mind why the splines broke up. They exist purely to ensure that the nut can be tightened on the layshaft to enable the hub to be forced onto the cone.

The fit on the cone is what does all the work if correctly tightened. The splines are the equivalent of a flywheel woodruff key & we all are aware of the hard learning process associated with the confusion about that….. ;)

Jees, I always thought they were to take load( like a gear) from shaft to wheel

Thanks for all of the info. I have a chrome AF uni one now and starting to fit. I didn’t realise that the uni hub came with a cone, so also purchased a separate uni cone and shim washer. It turns out that the cone that came with the hub is slightly deeper (17.6 mm) then the separate uni cone which is 17 mm exactly. Both have the same 8° taper.

Do I fit the cone that came with the hub without a shim, or do I also add the shim, or do I fit the smaller width cone and Shim. Or does it even matter?
