What you gain

25 W

That's what we saved in internal testing, in race position, against a conventional setup. At 40 km/h those aren't numbers: they're minutes by the end of a half Ironman.

The profile is worked out so the air runs clean over your forearms, and the cabling goes inside so as not to break the flow.

Where your elbows rest

Armrests and elbow pads large-format

The TT doesn't take the small clip-on pad: it carries the large armrests, with far more contact area. Underneath runs the same printed lattice, denser under the elbow and more open at the edges, and you can see it along the edge of the part.

Spreading the weight over more surface is what lets you hold the position for three hours without your arms going numb. They're worked out from your weight and from what you actually load onto them in your real position.

Before we make it

What we need to make them to your measurements

01

Your position

A side-on photo on the bike, or your bike fit data if you have it.

02

Your handlebar

Make and model. With that we know how we fit it and whether an adapter is needed.

03

Forearm and weight

Forearm length and your weight: they set the length and the density of the pad.

04

One or two

Whether you want one grip or two, and whether you run electronic shifters.

None of this needs filling in now: when you buy we message you on WhatsApp and we sort it out in five minutes.

{{ product.description }}
Are they compatible with my bike?

Yes. CarboXtrem TT aerobars are compatible with every brand and model, and they fit the standard handlebars on the market. On top of that, every unit is made to your size, so the fit is worked out for your particular setup.

Do you really save 25 W?

In simulations and internal testing in race position we have recorded savings of up to 25 W against standard setups, thanks to the optimised aerodynamic profile. The figure depends on your position, your speed and your equipment.

Are the TT aerobars 3D printed?

No. The body is hand-laid carbon fibre, with the fibre orientation worked out to give precise torsional stiffness. 3D printing is kept for certain parts and for the support pads.

Who are they for?

For triathletes and time trial riders after an aero position they can hold: anyone who spends hours on the aerobars and needs the posture to last to the end, not just the first few kilometres.

What measurements do I need to send, and how long does it take?

After you buy, we guide you step by step through taking the measurements (arm length, width and your handlebar details). Manufacturing usually takes about 2 weeks, and express shipping 24 to 48 hours.

What warranty do they have?

Lifetime guarantee against manufacturing defects and a perfect fit guarantee: if something doesn't fit as it should once mounted, we put it right.

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.
