Read about the covers on Bike Rumor



If you bike is not the CAAD 10, 8 or Super Six evo, you will probably need micro spacers between our product and your headset to ensure that our cap is not contacting your headtube. 3 are included with each cover. If you do not fully understand how the cover works, please get in touch with your local bike shop to help with installation to avoid damages to your bike or headset assembly. If you have never adjusted or worked with integrated headsets before, please seek help to make sure this is done properly.

To be sure that the SLAM THAT STEM Headset Dust Cover is working properly, you should be able to pass a piece of paper between the gap of your Dust Cover and your headtube. If you cannot do this and they are making contact, you need a micro shim or two. If you tighten the headset down without the proper micro spacers, the Dust Cover and the bike can get damaged. SLAM THAT STEM is not responsible for damages incurred to the bicycle, dust cover or user as result of improper installation. Remember, if something on your bike feels wrong, it is wrong, and you should stop riding it and bring it into a shop to be looked at! If your back hurts as a result of slammage, just do more core work and HTFU.
