Your cart is empty.The original centerlock rotor shim - tested and perfected since 2016. Comes pre-slit for perfect, seamless installation. No additional work required, just install and ride. Use for precise alignment of your disc brake hub rotors to make switching wheels a snap. Pack of 4 stainless shims, each shim is .25mm thick. For centerlock hubs/rotors. We recommend a maximum of 4 shims per hub to maintain sufficient thread engagement between lock ring and hub. Also, if your rotors are more than 1mm off from hub to hub, something is probably amiss.

A must-have if you swap out wheels on your bike. I can't believe that I just discovered these! Swapping wheels is so much easier.

I just installed a new Campagnolo Super Record EPS groupset. The pad spacing on the hydraulic calipers is extremely narrow. So after getting one wheelset perfect, I was bummed that my daily training set had the rotor slammed against the inner pad. I have to credit ChatGPT with suggesting rotor shims which I didn't know existed. But after doing a search here I was delighted to find the November guys again. (I have one of their carbon clincher wheelsets.) Everything is sorted now. The only real challenge is removing them. (I experimented with two-up on one rotor and it was a bit of a faff getting the top one off.) Overall, super happy.

A little pricey, but these things are a huge time saver if you have multiple wheelsets that you want to line up with your rotors/bikes. I was able to get 3 sets of wheels to all align perfectly for use on 2 different bikes.

2 shims on my rear wheel. 1 on the front. Perfect alignment. Smooth and silent. No caliper adjustment needed. Thanks for this perfect product.

I upgraded my rear wheel from a 141qr to a148. I purchased an adapter to make this conversion. I could not get the rotor to line up with the caliper. These shims worked perfect. It aligned my rotor perfectly with the caliper. I did use all four to do this. Thank you so much for this. I don't know what else I would have done. 10 out of 10 recommended.

I have a bunch of different wheel sets that I share between my two cyclocross bikes. Using these shims, I have been able to set up all the rotors so there’s zero rub with any wheelset on either bike. The thickness is ideal - one shim makes a real difference, but they are thin enough that you can dial in the alignment perfectly. Size is spot-on; they install easily, and precisely fill the hub-rotor interface on all my hubs. DT Swiss, Bitex, Formula, Novatec, Shimano… all work great. I also use them on i9 hubs on my MTB.

I just installed one of these shims on two different Formula hubs (RX-512 and RX-412) and they seem to do the job. The material looks great and the thickness is a true 0.25mm. As seen in the photos, the internal diameter of the shims is 33mm and the outside diameter of my hubs is just under 34mm, so they don't sit quite flat, and there is gap in the shim once the lockring is torqued down. I'm not sure if this is common, or if my hubs are just larger than normal. I don't think this will cause any real issues, except for maybe giving dirt a place to collect. I'm glad November Bicycles provides these since it seems to be difficult to find them elsewhere.

While the material looks hugh quality, mine were not split. Unfortunately when trying to split myself it created a raised edge which makes the rotor not sit perfectly flat. Sounds like I may not be the only one with this issue sadly.
