Ritchey's carbon SuperLogic ErgoMax carries a compact bend and ergonomic top section onto mixed-surface rides, built for long days on and off the road without punishing your hands.

Highlights

  • Full carbon fibre construction with a matte UD carbon finish
  • Compact bend with an ergonomic top section for reduced fatigue
  • 20mm rise at the clamp and a 17.5° drop flare for a stable, upright drop position
  • 90mm flat centre section for clip-on extensions or bar bags
  • Full or partial internal cable routing, compatible with the Shimano EW-RS910 Di2 junction box
  • Available in 38cm, 40cm, 42cm and 44cm widths

Geometry

113mm drop, 70mm reach, 5° backsweep and a 2° flare-out complement the 17.5° drop flare, for a stable position on mixed terrain without reaching aggressively forward.

Compatibility & fit

31.8mm clamp and 31.8mm accessory mount diameter. Stem clamp torque is 5Nm (max); lever and shifter clamp torque is 5Nm (recommended). Not compatible with the Ritchey C260 stem. Wider cable housing may interfere with internal routing.
