What Are MTB Topcaps?

An MTB topcap, also called a stem cap or headset cap, sits at the top of your mountain bike’s fork steerer tube. On a threadless headset, the cap and its centre bolt are used to set the headset bearing preload during adjustment, helping remove unwanted play while allowing the steering to turn freely.

It’s also one of the details you see every time you look down at your bike.

Make Your Bike Yours
