September Special: Free carbon extensions with purchase of Mono-Riser Aerobar (applied in cart)

Test page 51 Arm Cups

We developed 51 SPEEDSHOP extension range to improve rider performance by focusing on comfort, positioning, and aerodynamics.  Backed by our advanced bike fit knowledge, we utilized 3D printed segments to construct extension shapes into neutrally orientated wrist positions promoting upper body comfort and relaxation.

Based on rider data gathered during our bike fit process, we developed three unique extension shapes to cover a wide range of rider fit preferences.

But, which shape is right for you? Lets start by considering a few items….

  • Is your TT cockpit fixed in a flat position or does it angulate?
  • Are you looking for a high, moderate, or neutral hand height position.
  • Do you want maximum arm pad contact or will you place your elbow into the pad?
  • What sort wrist orientation do you prefer?
  • What shifters do you use? Shimano Di2 (long), Shimano Synchro (short), SRAM eTap (short), Mechanical?
