  • Both aero and incredibly light, stiff and precise, comfortable and absolutely thrilling to ride. A bicycle frame moulded in one single piece. Together these characteristics produce noticeable performance gains.
    You don’t have to be capable of 40kph + sustained speed to reap the aero, and momentum gains, that most high end carbon bikes require from their riders. Even at lower speeds you will notice the difference.

GramCarbon at IronMan Greece 70.3

In April 2019  we showcased our frames and bike builds at the inaugural Ironman 70.3 in Costa Navarino in Greece.  For us the expo was a major milestone because as a young company, it is the first time we have exposed our product to a highly sophisticated and experienced international audience. We were hugely encouraged by the response and feedback to the incredibly light aero frame and build Triathlon bikes we presented that can weigh in at only 6kg.  See the expo time lapse video
