We offer a range of caps, materials and finishes - laser etched, deep laser etched, carved, full colour and engraved - different designs suit different finishes - if you get stuck and need some advice/help - just get in touch and we will do our very best to help you.


On aluminium, all our laser etching comes out crisp, white and cut into the surface of your chosen product.

Laser etching is done on shiny anodised and titanium headset caps. The accuracy and detail will astound you and all our standard caps are laser etched to give a high quality feeling of depth and definition to the end product too.

We can add deep laser etching on certain designs as well.


Deep laser etching is the ideal finish on your product where you want to add depth and an extra dimension to your product. All our etching is precise, detailed, crisp and clear, but deep etching takes the finish to a new level of quality.

Our titanium headset caps, carved headset caps and stealth headset caps come with deep laser etching as standard.


All titanium etching is deep etched and then coloured with either a grey, gold, blue or RAINBOWNIUM (a red/blue mix) effect as standard - you just pick the colour you want for your design. On certain designs, you can also have all 4 colours together too - please ask for details.

We offer TiTanium headset caps in polished silver, gold and black.


Our carved products are ultra deep etchings. Designs with big areas of etching are best suited to this finish. We can advise you, if you are not sure yourself. Chunky text and bold images create the best effects.

A carving leaves a grey finish, deep into the metal - which we can also fill with colour too.


Our full colour caps are filled with bright and vibrant HD colours - any design/any image/any solid colours you want you like. The base caps can be black, white, silver or gold - depending upon the design chosen. In certain circumstances, we can even apply a metallic colour to the design as well.


Engraved headset caps are the ultimate in design, detail and quality. Engraving out the metal of your design will leave a silver finish, which we can then fill with colours of your choice.


Diamond engraving is a traditional process that leaves a really crisp outline of your design on any style of cap you want. The outlines are created in silver and the effect is beautiful, with as much detail as you want.

Particularly great results appear on raw titanium, brass, steel and copper headset caps.


All our stealth products are firstly deep etched with your chosen design and then the final process is anodising. This gives the effect of matt black on all the design elements we have just deep etched, leaving the rest of the cap shiny black.

We can, in some cases, also produce stealth caps in other colours too, where you end up with two shades of the colour you choose. 

^^ YES ^^ we also make all the headset caps for Campagnolo in Italy too.
