![]() "We couldn't produce that shape by any other sculpt, basically 1mm wall thickness, a very fine gap going down 25mm. When we push the joint in the tube it splurges out any excess, ensuring the adhesive is absolutely covered, the best possible joint. it not only reduces peel loads, but also the way we fill.the double lap joint with adhesive. "We've seen bonded frames in the past and where they fail. "One of the key things is those double lap joints," said Haythornthwaite. RBC said it has placed high-strength-to-weight ratio titanium in areas of maximum stress and connected them together with high-stiffness-to-weight carbon composite tubes. ![]() ![]() They say that 225,720 geometries are possible. A CAD model of the entire bike frame is quickly generated to ensure the optimum fit, with 11 titanium lugs built around the customers’ exact requirements.īath-based HiETA, a specialist AM development and project engineering company, introduced RBC to project partners Altair and Renishaw and also provided the frame's parametric CAD model. ![]() ![]() To order a frame, customers use RBC's website to input their height, inside leg measurements and arm span, from which the size of the frame is then calculated. RBC founding partner Ed Haythornthwaite added that technology developments would eventually bring bespoke bikes to a wider market. For £4,395 the Robot Bike Co (RBC) will build customers a bespoke frame with carbon fibre components and tubing bonded into the double lap joints of additive manufactured lugs made from powdered titanium.ĭespite the price tag, RBC maintains that the R160 fulfils criteria missing in today's mountain bikes, with AM parts allowing for customisation in a market more used to moulding carbon fibre frames in three sizes. ![]()
