Blackbird Overarm

£339.00 – £410.00

Carbon Fibre Twin Bottle Mount System

Another World’s first in aerodynamic performance aids. Our innovative concept developed over a 5 month period and several Wind Tunnel refinement sessions allows two aero water bottles to be positioned directly above the forearms bridging the gap between hands and upper arms reducing drag over a wide range of yaw angles and wind speeds while providing extra hydration capacity. Designed to be fitted onto our Blackbird Mono armrest range or could also be used with a compliant central stack bridge.

ATTENTION – IMPORTANT

  • Intended for use by Professional Triathletes on non technical courses with good clear roads to be able to gain an advantage from use.
  • This component is intended for Middle / Long distance Triathlon racing only.
  • We do not recommend using for mass participation Age Group events or on technical courses where this could affect handling reaction in an emergency.
  • We do not recommend using higher sided armrests as this may cause operational difficulties.
  • It is the responsibility of the rider to determine how safely they can use this component as an addition to their own cockpit componentry.
  • In the event of this component being banned by any organisation and no longer permitted for use we can not refund

Description

Savings of up to an incredible 23 watts can be achieved at higher interaction speeds with a compatible mantis type TT position when key positioning factors are followed. Because of the importance of this we will only supply this performance aid after an email consultation to determine correct width etc. Incorrect positioning can result in an increase in aerodynamic drag.

The BLACKBIRD OVERARM system comprises a main carbon fibre mounting plate which has design features allowing easy entry and exit from a race position while the bottles sit in their optimal aerodynamic position when using the tribars. This main plate is mounted at a pre-set angle onto a height adjustable central carbon stack to fine tune clearance. The inline and lean angle positioning of the bottles is also pre-set with a slight allowance for further fine adjustment.

This product is intended purely as a race day Aerodynamic-Hydration performance aid so is easily fitted or removed in seconds via two bolts.

SIZING GUIDE

Armrest width should be measured from outside right to outside left across the centre of the
armrests then check the guide to determine the most appropriate width from Small / Medium / Large.

Armrest Width:
200mm to 230mm = Small
230mm to 250mm = Medium
250mm to 270mm = Large
