Buying for someone?

Not sure what to choose? Don't worry. Hexcaps fit most mountain bikes and make an easy gift for riders who want their bike to stand out.

What You Need to Know

Pick a design they'll love. You don't need to know their bike's size, wheel size or brand.

For an extra check, look at the middle of their handlebars. If there is a round topcap held in place by one bolt, a Hexcap will most likely fit.

What Comes With It?

Every Hexcap order includes:

One graphic topcap
One M6 bolt
Help checking the fit
Simple fitting instructions

Tools are not included.

What Bikes Will It Fit?

Hexcaps are made for most modern mountain bikes and dirt-jump bikes with a standard topcap.

They may not fit bikes with:

A special headset system
A tool hidden inside the steerer tube
A topcap with a different bolt or unusual shape

Still unsure? Send us a clear photo of the middle of the handlebars. We'll check it for you.

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

A HEXCAPS topcap replaces your plain stock cap with a design that suits your setup. Match your bike’s colours, choose a graphic you love or add an engraved detail to your cockpit.

Explore our MTB topcaps collection to find your favourite design.

Will It Fit My Bike?

HEXCAPS topcaps are designed for standard bicycle headset top-cap setups. Check this product’s specifications for compatibility before ordering.

Bikes with integrated steerer tools, special headset systems or an unusual topcap may need a different solution. Unsure? Send us a photo of your current setup and we’ll help you check.
