Product Information

Full details

The Thomson Dirt Drop Gravel Handlebars are designed for gravel cyclists and adventure riders who prioritize stability and ergonomic comfort on rough surfaces. Featuring a 25-degree flare, these bars provide superior control during technical descents; however, the wider profile may feel unconventional for traditional road cyclists used to narrow, race-oriented drop bars.

Troubleshooting

Handlebars slipping or rotating under load

Check that the stem faceplate bolts are torqued to the manufacturer's specification. Ensure there is no grease between the stem clamp and the handlebar.

Creaking sound while riding

Disassemble the stem faceplate, clean the contact points with isopropyl alcohol, and re-torque the bolts to the recommended settings.

Pros and Cons

Pros

  • Increased stability and leverage from the 25-degree flare
  • Ergonomic top section significantly reduces hand and wrist strain
  • High-quality construction meeting rigorous performance standards
  • Easy to install and adjust for personal cockpit preferences

Cons

  • Wider profile may take time to adapt if coming from road handlebars
  • Not compatible with 25.4mm or 26.0mm legacy stems
  • Increased width can affect aerodynamic efficiency compared to traditional road bars

Setup, Compatibility & Care

To install, ensure your stem has a 31.8mm clamp diameter. When attaching the handlebars, center the bar accurately using the alignment markings and tighten the stem faceplate bolts in an 'X' pattern to distribute pressure evenly. Avoid over-torquing the bolts to prevent damage to the material. For maintenance, keep the handlebar tape clean and replace it periodically to maintain grip and comfort. Regularly inspect the bar surface near the stem clamp for any scratches or signs of fatigue. To clean the bars, use a damp cloth with mild soap; avoid harsh chemical degreasers that could damage the finish.
