Triathlon & Time trial (TT) bikes Sometimes it’s just about going as fast as you possibly can. If that’s the case then you need a bike purpose-built for one thing only: Speed. Everything about Triathlon and Time Trial bikes says ‘Fast’. Aerodynamic frames, handlebars, seat post and wheels help you slice through the air with minimal drag. Couple that with an aggressive aerodynamic seating position and you can propel yourself in excess of 30mph. With a number of accessories to aid you, including aerodynamic water bottles and handlebars to get you into the optimum riding position, it’s time to get out there and destroy your personal best.
