The ENVE Clip on Bar Extensions are perfect for adapting your road bike for improved aerodynamics during races against the clock – whether time trial or triathlon.   ENVE has created two versions of this highly-adjustable lightweight carbon tri extension: a model suitable for all 31.8mm round-tubed road bars and an ENVE SES optimised version designed specifically to integrate with the aero profile of the ENVE Aero Road Handlebar.   These are the perfect option if you're trying your hand at triathlons or time trials before committing to a full-on tri bike. They're also the ideal solution for hilly time trials where saving weight by riding a lightweight road bike trumps out-and-out aerodynamics. Meanwhile, ultra-endurance riders will appreciate the additional aero benefits and arm positions on offer.   The extensions, clip-on clamp/receiver and pad carriers are all expertly made from uni-directional carbon fibre for strength, low weight and vibration absorption – aided by the comfy neoprene pads.   Thanks to ENVE's cut-marked extension design, the extension can easily be trimmed to accommodate virtually any rider's desired position with either a J-bend, S-bend or straight shape. Due to the clip-on nature of the bars, width adjustment is dictated by the width of your drop bars, so there's plenty of room to tailor the perfect fit.
