Product Description

Radon Spire Disc 8.0 – Road Bike Carbon

The Spire Disc 8.0 marks Radon’s entry into the world of disk-equipped racing bikes. The Spire Disc is the ideal mobile base both for long tours and for short, snappy after-work get-togethers with your pals.

Highlights of the Spire Disc 8.0

It is powered by Shimano's renowned Ultegra group with its compact crankset and large cassette, so that long and steep uphills don’t become tortuous. Newmen’s light and stable components enable you to have an ergonomic sitting position. Continental Grand Sport tyres are perfect for all kinds of weather and kilometres of training.

The Spire Disc Family

The SPIRE carbon classic is back with a bang and carries brake disks. Thanks to its optimum rigidity values and a lightweight carbon frame, the SPIRE DISC is a must for ambitious tour riders with plenty of stamina. The streamlined design lowers the drag and has a tidy appearance.

The Spire Disc Frame

The highly rigid carbon frame wins you over with its low weight and high stability. An ideal sitting position maximises the transmission of power and makes you keen to tour long distances. A seat post with a diameter of 27.2mm in combination with the flexing rear end offers plenty of comfort, and the 28mm tyres add their bit to the bike’s positive vibes.
