Our Range Of Triathlon & Time Trial Bikes For Sale

99 Bikes has a massive range of triathlon and time trial bikes from the best brands available in Australia. Both Triathlon bikes and time trial bikes are designed and built specifically for competition in order to optimise efficiency in both aerodynamics and power transfer through frame geometrics which become increasingly more important in racing.

Triathlon Bikes

Triathlon bikes often referred to as a part of the aero bikes range are designed for riders who compete in triathlons. Immense impact on results may take place if a traditional road bike were used instead of a triathlon bike in competition. Triathlon bikes are designed with aggressive frame geometries, shorter head tubes, integrated handlebars otherwise known as aerobars, and typically feature steeper seat tubes all working to bring riders to the most aerodynamic frontal position.

Time Trial & Track Bikes

Time trial bikes (TT bikes) are considered to also be a part of the aero bikes range, while occasionally being known as track bikes. Track bikes and triathlon bikes share many similarities in featuring increased aerodynamics, one of the main distinguishing factors is seat position. Time trial bikes need to adhere to regulations set out by the International Cycling Union (Union Cycliste Internationale, UCI), one of which requires the saddle nose to be 5cm from the centre of the bottom bracket.
