Mount plate for BTA system

Regular price €74,90
  • 30-day returns
  • 2-year warranty
  • Crash replacement

The AeroGain Mount Plate allows you to connect your offset, straight, or double bottle BTA spacers securely to your setup. Ideal for riders upgrading to a dual hydration system or customizing their aero cockpit layout.

  • Compatible with all AeroGain BTA spacer types

  • Works with double bottle, offset, and straight configurations

  • Needs a gap between the extensions, because the plate’s bolts protrude below it. Fits, among others: the Specialized Shiv TT, Argon 18 E-117 and E-118, Cervélo P-Series, Trek Speed Concept, BMC Timemachine 01 Disc and Speedmachine, Cadex Tri, Cube Aerium C:68, Factor Hanzo, ONE and Slick, Giant Trinity Advanced SL, Felt IA 2.0, Quintana Roo V-PRi, Cannondale SuperSlice and bikes with Vision Metron TFA aerobars; not the Specialized S-Works Shiv Tri, Argon 18 E-119 or Cervélo P5.

  • No spacers included — this is the mount plate only

Use this as the foundation for your AeroGain hydration setup.
