Thomson Carbon Road Handlebar – Lightweight Road Drop Bar for Racing

The Thomson Road Handlebar is expertly crafted from high-quality carbon fibre, designed to meet the demands of modern road racing. Featuring a mild wing shape on top, it provides a comfortable grip while maintaining an optimal hand position. The clamping area is wide enough to accommodate aero bars, and the mid-compact reach and drop offer versatile riding positions for enhanced control and comfort. Its thoughtful design ensures freedom of hand movement without locking out your wrists, while housing can be taped neatly thanks to the shaping on the underside of the wing—eliminating the need for narrow housing channels or internal routing that can reduce bar longevity. Certified to EN and tested to DIN+ standards, this handlebar combines safety with performance.

For cyclocross enthusiasts, Thomson presents the carbon CX bar—a natural evolution from the road bar for the most demanding off-road seasons. Its twin flats on the bottom enable secure taping of housing, creating a smooth round bar when wrapped. The top profile is as wide and round as possible, providing ample space for hands and auxiliary brake levers. Engineered to endure the rigors of cyclocross racing, this bar is also certified to EN and tested to DIN+, ensuring reliability under tough conditions.

Thomson’s carbon fibre bars utilize a unique layup of three different fibre types, including high-strength carbon fibre, strategically placed to balance stiffness and flex where it matters most. The carbon fibre is sourced from Toray, a leading supplier for aerospace giants like Boeing and Airbus, and combined with tailor-made Nano Epoxy Resin to deliver exceptional impact resistance. Unlike other bars made from multiple pieces glued together, these bars are moulded as a single piece over an EPS mandrel, preventing internal wrinkles and enhancing durability.

Available in multiple widths, the road drops range from 137mm to 143mm depending on size, while the cyclocross drops are slightly shallower to suit off-road handling. Additionally, 1.5K woven impact ends protect the unidirectional fibres from damage due to impacts, extending the life of your handlebar.
