    Argonaut Cycles | Bespoke Carbon | Exclusive to G!RO

    Argonaut is truly custom carbon, born and bred in the Pacific Northwest, USA. Argonaut uses carbon not because it’s pretty, not because it makes a good story, but because it makes the best bicycles. Argonaut are driven by a singular purpose: To take your unique performance requirements and transform them into something real.

    Argonaut have joined with ChrisKing Components to release the amazing T47 Bottom Bracket | Details here..

    Availability |

    Argonaut is making road frames for a select number of customers. We want to make sure every customer gets the attention they deserve, and we meet our commitments to the minute. Please inquire about current lead times and availability.

    Each Argonaut order through G!RO will be treated on each individual basis. We will work with you step by step during the order process here in the UK, and Ben over in the US will work closely with you to ensure that you have the bike that suits you perfectly.

    Below is some more detailed information about these stunning bikes. If you want to find out more about Argonaut or discuss ordering, give us a call 01372 701701. 


    Layup Process |

    At Argonaut, we lay up the carbon fiber on the bladder, as opposed to in the tool. By building individual frame parts layer by layer on a rigid internal bladder, itʼs possible to achieve 360° of consistent, controlled wall thickness. Laying up parts on the bladder instead of inside the mold eliminates stress risers, and guarantees predictable road feel and handling characteristics.
    Beyond ˮLight and Stiffˮ
    Carbon fiber is the best custom bike material available for one simple reason: The degree to which it can be engineered and modified, in order to deliver a huge of range of performance results, is unmatched. There is much more to making a bicycle with amazing ride quality than shedding grams and beefing up the bottom bracket. You need to consider not just every tube length and frame angle, but every aspect of each tubeʼs role in the whole frame.

    Adjustable Molds |

    The cornerstone of the Argonaut process is a set of adjustable frame molds. Weʼve engineered our tooling so that all frame angles and frame section lengths are resolved inside the tool during the molding process, rather than modifying them after theyʼve been molded. The result of this is really the Holy Grail of custom carbon fabrication: technologically sophisticated frames that are truly custom, each and every time. Youʼll never see an * after the word ˮcustomˮ on our bikes.

    Bladder Molding Construction |

    Rather than bonding and wrapping individual carbon fiber tubes, the Argonaut frame is made up of seven molded frame sections, each with a layup pattern specific to that customer. Molding complete frame sections allows us to engineer every part of the frame to custom specifications, especially the crucial intersections. The process produces zero redundant material, and gives us complete control of the tube wall thickness.

    Proprietary Technology |

    Argonaut frame parts are made from scratch. That means each piece starts with individual sheets of pre-impregnated carbon fiber, which together make up whatʼs called the layup pattern. The layup pattern is what determines how each frame part will perform and what characteristics it will impart to the overall ride. Layup patterns vary in terms of the amount of fiber in each pattern, the modulus of the individual fibers, and most importantly, the orientation of the fibers.
