Road bike stems

Setting the Position

The stem connects the handlebars to the fork steerer and determines the position of the upper body. Its length, typically between sixty and one hundred thirty millimetres, adjusts the distance between the saddle and the handlebars. Its angle, ranging from zero to plus or minus ten degrees, raises or lowers the handlebars. Changing the stem is the easiest way to fine-tune your position for more comfort or aerodynamics.

The Components

Road components also come in various types:

• Handlebars and Bar Tape.
• Headsets and Cups.
• Saddles.
• Seat Posts.
• Pedals.

All components are gathered on the peripheral components page.

Two Systems

The ahead stem, which tightens around the steerer, is found on modern bikes, with a handlebar clamp diameter of thirty-one point eight millimetres generally. The threadless stem, inserted into the headset tube, like those from Newton or CGN, is used on older bikes and fixies, and can be adjusted in height. The aero stems, such as the Look Combo Aero or the Pro Vibe Aero, have integrated cable routing.

Comfort and Tightening

The Cane Creek eeSilk features an elastomer that filters road vibrations, ideal for long distances and rough roads. The Controltech stem for electric bikes houses the motor's display. Always adhere to the torque settings indicated on the stem, tightening the screws in a cross pattern, especially with carbon handlebars that are prone to crushing.

Good Deals

Great deals can also be found in the good deals, promotions, clearance, sales, and Black Friday. The new arrivals showcase the latest collections, and items shipped within 24 hours are prepared and dispatched in 24 hours. The highlights of the year follow a consistent order: the Black Friday at the end of autumn, the holiday season, the winter sales, the French Days in spring, followed by the summer sales and back-to-school.

Frequently Asked Questions

What length of stem should I choose for my road bike?

On a road bike that fits your size, the stem typically measures between ninety and one hundred twenty millimetres. A shorter stem straightens your position and makes steering more responsive, while a longer one stretches the torso.

How do I know what diameter stem to take?

Two measurements matter: the diameter of the fork steerer, usually one inch and an eighth, and that of the handlebars, most often thirty-one point eight millimetres for road bikes. You can check these on your current stem or on the bike's specifications.

What is the difference between an ahead stem and a threadless stem?

The ahead stem tightens around the fork steerer on modern bikes. The threadless stem, like those from Newton or CGN, inserts into the headset tube of classic bikes and can be easily adjusted in height.

Is a carbon stem worth it?

A carbon stem, like the Look Combo Aero, saves a few grams and improves aerodynamics by integrating cable routing. It requires precise tightening with a torque wrench to avoid damaging the fibre.

What is the purpose of a suspended stem?

The suspended stem, such as the Cane Creek eeSilk, includes a small travel that filters road vibrations before they reach your hands. It is popular on gravel bikes and for long rides on rough roads.
