product description
The Xlab Carbon Wing sets the standard of what any rear hydration system should aim for: lightweight, extremely functional, aerodynamic, and of course carbon. Xlab has been designing the Wings for nearly a decade and their reputation has only grown, with many top professional athletes electing to use their Wings as a necessary tool for Ironman success. The Xlab Carbon Saddlewing is the new generation of rear hydration systems.

Rear carriers should not interfere with the air on the rider’s back, but instead fill in the turbulence ‘hole’ behind the riders posterior, thereby reducing the rider’s drag (which accounts for 64% of energy used on a racing bicycle).


The Xlab Carbon Wing's initial goal was to solve the problem of storing keys, cell phones, cash, tire levers, and other essential items during training and come race day. These and other items can be stored in a saddlebag which drops vertically and easily into the rear ‘luggage compartment’ and is secured by the top X-Strap.

In addition you have a couple of choices for storing your CO2 cartridges and Microflate, or Speed Chuck on the rear of the Carbon Wing, using the optional hexagonal X-NUT or placed in a saddlebag.

The Xlab Carbon Wing also makes it simple to attach tires and tubes, which always seem to become an issue especially on the night before a big race! Now tires and/or tubes can be attached neatly under the Carbon Wing either inside the strapped on saddlebag or without a bag and just with the included strap.


The Carbon Wing wants you to stay hydrated, which is easily done by mounting a bottle cage on the rear or one on each side.


One of the key features, invented by Xlab, is the dual mounting holes for the saddle rail clamps. One position sets the bottle cages close to vertical and the other inclines the cages for a rider's preference.


Without hardware the Xlab Carbon Wing weighs only 55 grams!

Includes: Carbon Wing 400i, XSW-Straps and mounting hardware

Note: Bags, bottle cages, and inflation accessories sold separately.

Shipping Weight: 1.0 lbs.

Great for training
July 19, 2017
I use this, all loaded up for training but on race day I minimize down to just hydration. Some people have had issues with bottles launching but I have only ever lost one with this set up and it was over the rail road tracks in Chattanooga. Overall, I'd recommend it to anyone who asks.
A little pricey but this is triathlon- everything is!

nice product...

It is a bit pricey, I took advantage of Trisports sale/coupon. I bought the Carbon Wing 400i rear carrier replace the rear seat post water bottle holder that came with my Cannondale Slice. It is a nice piece and easy to install with my ISM saddle. I will be using this system for my longer distance tri's where I need additional water bottles and flat kits.

What to say, XLab just gets it! Yes is pricy, but hey is carbon so what do you expect. Perfect setup of your 70.3 or 140.6 race.

The ONLY rear carrier that has not broken (snapped) or parts falling off on rough roads and overall. Well worth the additional cost!
Sturdy, looks slick and lightweight

In Love with XLAB!!!

I have found no problems whatsoever with my 70.3 system. It works flawlessly and looks very cool on my QR Caliente with Cosmic Carbonne wheels. Excellent choice in lieu of more expensive Zipp wheels

Blast off!!!!
July 26, 2011
Ugggh...where to start. The fact it's well over $200 by the time to get all the junk to go with it should be a clue. I had to turn it upside in order for it to work with my ISM Adamo saddle, and when I did that, there was no way for me to put a bag on it anymore. Oh and the first 70.3 I did with it, both of my bottles launched within the first half hour and I had to stop at an aid station to fillup my speedfil...that was with the Gorilla cages. I returned it.
Looks cool
Doesn't fit ISM Adamo, Poor design, Bottle lauches

should be banned
March 5, 2011
rear mounted hydration systems should be banned from tris. They just dont work. Good Idea, bad device. I have had this system for two years and i have lost many bottles off the back of my bike. I have dodged many a bottle on bike courses from these. But what did it for me was breaking my collar bone when my own bottle landed in my own back wheel. No more. Go with a frame mounted system like speedfill or just a regular bottle cage and have the piece of mind that your nutrition isn't gonna fly off and knock sombody off a course.
Bad Mount, Weak Material
