CarboXtrem, a leader in 3D printing for high-performance cycling

At CarboXtrem we specialise in 3D-printed cycling components for riders who will not settle for off-the-shelf.

We design and manufacture aerobars, grips, saddles and other key parts to millimetre precision, using materials such as carbon fibre and EPU 41 resin, the same ones used by leading brands like Specialized and Adidas.

Every part is adapted to your body, your bike and your discipline (road, triathlon, gravel). No generic sizes. No pain. Just performance.

I fitted them for a customer who had used other well-known brands and the difference is huge, above all in comfort, and in looks too. I will certainly buy again.

Frequently asked questions

How do I know it will fit my bike or handlebar?

Our products are made to measure. Just follow the configuration process and we will make sure it fits your model precisely.

Do I need special tools to fit it?

No. All our products are designed for straightforward fitting with standard tools. Where needed, we include a kit and a step-by-step guide.

What if it does not fit well or is not comfortable?

You have our perfect fit guarantee. If it does not fit or you are not happy, we help you put it right or we refund you.

Do they hold up to rain, mud and hard use?

Yes. All our products are tested in real racing conditions and made with technical materials such as EPU 41 resin and laminated carbon fibre.

How long does my order take to make and ship?

Custom manufacturing usually takes about 2 weeks. Once ready, it ships by express courier (24/48h within Spain).

Do you ship to other countries?

Yes, we ship internationally. You can check rates and delivery times at checkout.

Can I return the product if I am not convinced?

Yes. You have our perfect fit guarantee. If it does not suit you, we work with you until we reach a perfect fit for your bike and your body.

Given the nature of the product and its personalisation, custom products are guaranteed against manufacturing defects. This guarantee does not cover errors arising from incorrect measurements supplied by the customer, nor normal wear and tear.

What does 3D printed actually mean?

We use Carbon DLS technology, the same used by brands like Specialized and Adidas. That lets us build components adapted to you down to the millimetre.
