Product Information

Full details

The Thomson Round Drop Road Handlebar is designed for serious road cyclists and enthusiasts who prioritize precision, durability, and a classic riding feel. Crafted from 7000 series aluminium, these bars offer a robust platform for high-performance riding, featuring an ergonomic wing section that balances comfort with aggressive hand positioning. While these handlebars provide exceptional reliability and exceed ISO safety standards, riders who prefer carbon fiber for vibration dampening may find the aluminium construction slightly stiffer on long-duration rides.

FAQs

What is the reach and drop of these bars?

These handlebars feature a 72mm reach and a 147mm drop.

Are these bars compatible with clip-on aero bars?

While the round profile is conducive to many clips, always check the clip-on manufacturer's manual to ensure the bar material and diameter are approved for clamping force.

What material are these bars made of?

They are crafted from high-quality 7000 series aluminium.

What is the clamp diameter?

These bars use a standard 31.8mm clamp diameter.

Do these bars meet safety standards?

Yes, they exceed the ISO 4210-2:2015 safety requirements for road cycling components.

Can I use internal cable routing with these bars?

These bars are designed with a standard profile; check the specific routing exit points if your groupset requires fully internal cable integration.

Troubleshooting

Handlebars slipping in the stem clamp

Verify the stem bolts are torqued to the correct specifications and consider using a carbon/alloy assembly paste to increase friction.

Creaking noise when riding

Remove the faceplate, clean the contact surfaces with isopropyl alcohol, re-apply a thin layer of assembly paste, and re-torque the bolts to the recommended settings.

Pros and Cons

  • Exceeds ISO safety testing standards

Setup, Compatibility & Care

Installation of the TH-HB-E124 requires a standard 31.8mm road stem. When installing, always use a torque wrench to ensure the stem faceplate bolts are tightened to the manufacturer's specified torque settings, typically between 4Nm and 6Nm for aluminium bars, to prevent localized crushing. Ensure the bar is centered by aligning the center-markings with the stem. For care, wipe down the bars with a mild detergent and water after particularly sweaty rides to prevent corrosion. Periodically inspect the clamping area for any signs of stress or deep scratches that could compromise the integrity of the aluminium.
