Radon R1 FrameThe Radon R1 frame brings a little of the racing spirit to longer rides, after-work blasts with your training buddies or regular training sessions.
Entry into the upmarket racing bike class: Radon R1 Frame in black/antracite/yellowThe R1 series is an impressive testament to the fact that you can build first-class road bikes without the use of carbon fibres. The outstanding features of the triple-butted 7005 alloy frame are its superb rigidity values, low weight and agile ride characteristics. A super-lightweight set of tubes reduces weight while keepig rigidity intact, the top tube apostatizes by about 3cm on all models. The press fit bottom bracket brings bottom bracket rigidity to a new level. To enhance comfort values, we've developed a new Flex Stay rear triangle that can absorb vertical impacts without compromising torsional rigidity. This combination enhances steering precision and comfort, while reducing overall weight at the same time. With its racy geometry, outstanding rigidity and very low weight, the R1 represents dynamics, efficiency and riding pleasure - in short, all that is fascinating about road racing!

With Press Fit bearings, the bottom bracket bearings are pressed directly into the frame and not screwed in as usual. This gives a wider bottom bracket shell and allows us to build a wider down tube and more broadly-spaced chainstays. Every millimetre of additional width gives a significant improvement in lateral stiffness.
This steerer tube design is stiffer than a conventional straight steerer and yields a more secure ride feel even in difficult terrain. Minimal flex at the front of the frame means the greatest possible steering precision. With the larger steerer, the forks become more rigid. At the same time weight is saved due to the absence of bearing shells as the lower bearing is fully integrated into the head tube.
