Product Information

Full details

The DMR Wingbar MK4 is engineered for aggressive mountain bikers and trail riders who demand a lightweight, stiff, and highly durable cockpit setup. Developed alongside professional riders like Olly Wilkins, this handlebar offers an optimized geometry that excels in both technical stand-up sections and comfortable seated climbs. While its robust 35mm clamp diameter provides exceptional control and stiffness, potential buyers should ensure their current stem is compatible with the 35mm standard before upgrading.

No, this handlebar is specifically designed for a 35mm clamp diameter and will not fit a 31.8mm stem.

The total weight is 326g.

Is this handlebar suitable for downhill racing?

Troubleshooting

Handlebar slips within the stem clamp

Verify torque settings and ensure there is no grease or debris on the contact surfaces; use assembly paste if friction is insufficient.

Audible creaking sound from the cockpit

Check all stem bolts for correct torque; remove the bars, clean the interface area, and re-install following the proper tightening sequence.

Pros and Cons

Pros

  • Extremely stiff and responsive steering
  • Lightweight at 326g despite its strength
  • Professional-grade geometry reduces strain
  • Durable, heat-treated alloy construction
  • Wide 800mm profile offers excellent leverage

Cons

  • Requires 35mm compatible stem
  • Fixed 20mm rise may not suit all setups
  • Non-adjustable width requires physical cutting for smaller riders

Setup, Compatibility & Care

Installation requires a compatible 35mm stem. Follow your stem manufacturer's torque specifications strictly, typically using a torque wrench to tighten bolts in an 'X' pattern to ensure even pressure distribution across the clamp area. When cutting the bar to a narrower width, use a dedicated hacksaw and a cutting guide to ensure clean, straight edges, then lightly deburr the ends with a fine-grit file. To maintain the finish, wipe down with a damp cloth after rides; avoid using harsh chemical solvents that could degrade the Liquid Camo coating.
