Pressure where it belongs

3D carbon saddle
Carbon NEXUS

150 grams. No foam to flatten and no gel to shift: the mesh works like a suspension and spreads the weight between your two sit bones.

Integrated cockpit

Carbon handlebar
CarboX17

Bar and stem in a single piece of carbon, with the cabling routed inside. Stiffness where you push and some flex where the road punishes.

3D grips for MTB
Race Days

22 to 30 grams the pair. The mesh damps the buzz that ends up numbing your hands, and it doesn't slip in the rain.

Luis Maldonado Cano, of the bike shop Bikeland
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. I'll surely buy again.

★★★★★

I've tried the aerobars and it's far more than a good buy.

I think I'm going to enjoy them enormously and make the most of them while I prepare for the Barcelona-Calella Ironman.

RDCCustom aerobars

★★★★★

Excellent comfort and quality. The most important thing: being able to have it made to measure.

The product is excellent, no doubt. Very good treatment, quick, and thoroughly recommendable after having tried other saddles.

Rubén Darío RiveraMade-to-measure product

★★★★★

Investing without trying it first raises doubts, but I couldn't be happier.

A ride of almost six hours to test it and all I can say is I'm delighted. I've never tried such a comfortable saddle.

★★★★★

I'd been looking for aerobars for my integrated handlebar for a long time.

I couldn't find any model in the right size. I got in touch with CarboXtrem and they helped me with a custom solution.

★★★★★

Excellent product, with unique quality and finish.

They give great grip and great comfort. You can tell the level of finish on the product.

★★★★★

Very happy both with the advice and with the end result.

This is my second purchase. Spectacular; there's nothing like this material on the market.

I can stay on the extensions far longer without postural fatigue

After several months of use, the extensions for my BMC Timemachine 01 Disc work brilliantly. Made to my own measurements and position: they are genuinely comfortable and my performance has clearly improved. I had a small misalignment and Alfons sorted it out in under a week, at no cost.
