As of late, I've been building some centerlock wheels. I have no real compelling reason to use centerlock vs standard 6 bolt as it seems that when viewed as a system, weights are equivalent (system meaning hub and rotor weight). The one advantage I have found is for travel, and only if you remove your rotors to bag or box your bike. Removing centerlock rotors is a 30 second endeavor vs a few minutes for 6 bolt rotors. Plus the convenience of handling one lock ring opposed to 6 little bolts. But I digress.
As cyclocross season approaches I'm faced with the challenge of having a quiver of 3 sets of disc wheels, 2 six bolt and 1 centerlock, all align with the brake caliper when changing wheel sets. With 6 bolt there are rotor shim spacing solutions currently available on the market. I've been unable to find spacer solutions for centerlock so I had some manufactured! These little guys will fit standard 35 mm centerlock hubs (not the oversize and less common 46mm version). Each spacer is 0.3mm thick. I'm selling them in lots of 6 for $12 plus shipping! Get them before they're gone!
Finally a solution for spacing centerlock disc brake rotors! These are built for standard 35mm centerlock hubs. Spacers come as a pack of 6 and each spacer is 0.3mm thick. For more information please click: http://ferretticycles.com/blog/centerlock-spacers-now-available
