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.

Note : Please note that specifications are subject to change without notice, based on component availability and other factors.

Whether you're racing, riding your favorite development, or just enjoying your favorite route, you're fighting the wind with every pedal stroke.
A fight that's now a breeze with the BH RS1 4.5.

Lightness and rigidity
HCIM hollow-core internal molding technology: control and optimization of thicknesses in the most critical parts of the frame.
A compact frame without bubbles or imperfections.

The Kamm Tail profile of the RS1 model's tubes allows for a completely aerodynamic cross section.
Rigorous computational and fluid dynamics analyses were conducted to match the aerodynamic values of our G8 aero range.

The seatpost locking system is integrated into the down tube to optimize the aerodynamics of the top tube.
Low torque ensures maximum functionality.
The stem is available with an optional 15° offset to accommodate all riders in positions that require the best performance or comfort.

Using the BB386EVO system, the bottom bracket has an oversized diameter of up to 86 mm. In addition, increasing the diameter of the lower downtubes by up to 80mm reduces the thickness of the tubes and increases torsional stiffness and rear-end rigidity.
The RS1 has extremely short chainstays for a highly responsive bike that converts every pedal stroke into watts,
. But it also produces a short, aerodynamic rear end.

The new RS1 frame features ACR, which allows 100% internal routing of cables for a clean frame with no visible cables.
Wheel arch for tires up to 30mm wide
