| CarboXtrem Aero aerobars | Traditional aerobars | |
|---|---|---|
| Fit | Adjusted to the rider's arm length and biomechanical specifications. | Made in standard sizes with no individual adaptation. |
| Comfort and ergonomics | EPU 41 pads that absorb vibration, with the wrists at 50º for greater comfort. | Less scope for customisation and standard support. |
| Aerodynamics | Can be rotated towards the centre of the handlebar to improve aerodynamic penetration. | Static design with fewer adjustment options. |
Each aerobar is matched to the specific length of your arm and sets your wrists at an optimal 50º angle.

Spec sheet
Yes. CarboXtrem Aero aerobars are compatible with every brand and model of bike. Before making them we check your handlebar and your measurements, and after you buy we contact you on WhatsApp to guide you step by step.
Yes. All our products are tested in real race conditions, made with technical materials such as EPU 41 resin and hand-laid carbon fibre.
After you buy, we guide you step by step through taking the measurements: usually height, weight, arm length and your handlebar details. With that data we make the aerobar to your size, and you have our perfect fit guarantee: if something doesn't fit, we put it right.
Manufacturing usually takes 2 weeks. Once it's made, shipping normally takes 24 to 48 hours.
This is a product made to measure to your specifications, so it isn't covered by the standard right of return once manufacturing has started (article 103.c of Spanish Royal Legislative Decree 1/2007). Before we start making it you can cancel the order: write to us and we'll sort it out.
In exchange you get our perfect fit guarantee: if it doesn't suit you, we work with you and readjust it as many times as needed, at no cost, until we get a correct fit for your bike and your body. And if it turned out not to be adjustable, or there were a fault we couldn't put right, we refund you in full.
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. Your legal rights as a consumer regarding faulty products remain intact. See terms.
Yes, we ship internationally. Check rates and times at checkout.
We use Carbon DLS technology, the same one brands such as Specialized and adidas use. That lets us make components fitted to you to the millimetre.
