Single bottle BTA system

The AeroGain BTA (Between/Behind The Arms) system.

• Fits arm cups and extensions that clamp onto a plain surface. 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.
• Bottle placed in the aerodynamically optimal position
• Seamless clean design
• Different spacer angle options
• Choosing the same spacer angle as the angle of extensions results in a horizontal bottle.

• Comes with a 70 mm spacer. If you require a different height for the spacer, it must be purchased separately.
