Cube
Description
What size do you need?
Choosing the right sized bike depends on the type of bike, your height, your riding style, and your preference. A correct fitting bike will be more comfortable, more efficient and more fun to ride
Measure yourself accurately
To get started, measure your height and use the size chart available on each product description.
What to do if you are in between bike sizes?
If you are on the edge of two different bike sizes, don't worry, you'll probably be ok on either size (rather than thinking that one size will be awful and the other will fit). Indeed, bikes are adjustable: the seatpost can slide up and down, the saddle can move backwards and forwards and you can even switch out parts like the stem for different sized ones to help the bike fit better.
Finding out whether or not you should pick a bigger or a smaller frame is sometimes as simple as personal preference, but there are a few simple ways to work out which might suit best:
- If you’re flexible, you might prefer a shorter head tube, so the smaller size might work out better for you. You can use a longer stem to make the reach more comfortable.
- On a bigger bike, the reach to the handlebars will be longer. This means that if you have proportionally longer arms, you might be more comfortable on a bigger frame.

Developed in close collaboration with Cube athlete and World champion Lucy Charles-Barclay, the Aerium C:68X can rightly claim its title as the fastest frame we've ever made. Every detail, from the aero fork design, disc brake integration and in-frame hydration and storage systems has been designed with zero compromise, tested in the wind tunnel and then tested again under pressure, in race conditions. Lucy has full confidence in the frame and its configurable storage and hydration and now you can, too.
You know this bike is fast, because the Cube Aerium C:68X SLX is closely based on triathlete Lucy Charles-Barclay's World Championship-winning bike. Configurable hydration and storage options sit behind aero hatches, adding the ability to run up to two hydration systems for better self-sufficiency, even during long races. We fitted a Newmen Streem Aero/Sprint TT 60/80 VONOA wheelset shod with Continental Grand Prix 5000 TT tires and aero valves for rapid acceleration, superior aero performance and safe cornering grip. The Cube Aerium C:68X cockpit system puts the rider in the optimum position, with a huge range of adjustment for the aero bars. A Sram Force AXS 2x12 drivetrain with built-in power meter ensures the right gear is always right there. And absolutely all of it is crafted from our premium C:68X carbon. We sweated the detail, so your sweat can be translated into pure speed.
