Product Information

Full details

The Controltech CLS Gravel Handlebar is designed for gravel cyclists who prioritize a balance of lightweight construction and rugged durability. It serves as an ideal upgrade for riders looking to improve their bike handling on technical terrain through its specialized ergonomic geometry. While it provides excellent stiffness for power transfer, riders should ensure their stem is compatible with the 31.8mm clamp diameter before installation.

FAQs

What is the clamp diameter of these handlebars?

These handlebars feature a standard 31.8mm oversized clamp diameter.

Can I use these for road cycling?

While designed for gravel, they can be used for road cycling; however, the 12-degree flare is specifically optimized for off-road stability.

What is the reach and drop of this handlebar?

The Controltech CLS has a reach of 75mm and a drop of 130mm.

Are these handlebars compatible with clip-on aero bars?

You should check the specific aero bar manufacturer's instructions; ensure the clamping area is wide enough and the handlebar can handle the additional clamp pressure.

How do I determine if I need the 40cm, 42cm, or 44cm size?

Measure the distance between your acromion processes (bony points of the shoulders) to find your ideal width, though many gravel riders prefer wider bars for increased leverage.

Troubleshooting

Handlebar slipping in the stem

Verify that the stem faceplate is tightened to the recommended torque specification and ensure the clamping surface is free of grease or debris.

Creaking noises while riding

Apply a light layer of high-quality anti-seize or assembly paste to the contact points between the stem and handlebar.

Shifting or braking feels stiff after installation

Check that the wider flare hasn't created tight cable bends or kinks, and consider re-routing or shortening cable housings if necessary.

Pros and Cons

Pros

  • Improved stability on technical descents due to the 12-degree flare
  • Highly efficient power transfer thanks to the 31.8mm oversized clamp
  • Lightweight build minimizes added mass
  • Ergonomic geometry reduces strain on long rides

Cons

  • Fixed clamp diameter limits compatibility with older stems
  • Flare geometry may require re-indexing of brake and shift cables
  • Limited to gravel-specific geometry which may not suit pure road racers

Setup, Compatibility & Care

Installation requires a 31.8mm compatible stem. When mounting, use a torque wrench to ensure the faceplate bolts are tightened to the manufacturer's specified torque rating to prevent damage to the aluminum structure.

For care, periodically inspect the handlebar for scratches or signs of deep gouges, particularly around the clamp area. Clean the bars with a mild detergent and water, avoiding harsh chemicals. If the bars are used in salty or gritty conditions, ensure that cable housing entry points are kept clean to prevent grit from causing cable drag.
