Home Fitting Instructions



If your bicycle has been put together correctly, it is the stem clamp bolts that need to be torqued up correctly (they hold everything in place) NOT the bolt in/on your Headset Cap – once correctly built, you can actually safely ride your bicycle without a Headset Cap!

If you ever need to adjust the bearings in your headset – please use your original headset cap and bolt – then replace with your KAPZ & KAPZ BOLT when you have finished.


You will need a straight 5mm Allen/Hex Key (not one with a bobble) for all KAPZ products or for our carbon headset caps a T20 Torx key for the special titanium bolt and some grease.


The matching bolt that comes with your headset cap/bar-ends is made of aluminium, must be greased before installation and is designed to be nipped up gently with a 4mm Allen/Hex Key – NOT EVEN FINGER TIGHT – just enough to hold the headset cap in place.

If our KAPZ bolt is too long for your bicycle – simply cut it with a sharp hacksaw – measure twice/cut once – its an easy job.


Simply remove your existing cap and bolt, install the retainer in it’s place, add a tiny bit of grease to the bolt and the O’Ring on the back of your new cap insert and to the bolt and lightly nip it up – NOT EVEN FINGER TIGHT – as overtightening will damage the retainer – then gently push in the cap-insert into place.

Remove your old headset bung, carefully insert your new KAPZ bung and install securely using a straight 6mm hex key. Once installed, you can now insert and fix your KAPZ headset cap into your bung 🙂


Our custom bottles need just as much care any normal drinks bottle. They are dishwasher-safe and with reasonable use, should last a good while. As cycling is the only sport that uses a bottle-cage to hold the bottle in place, there may well be some wear on the bottle due to the normal use of a cycling bottle.
