The pivoting tiller steering

Challenge Fujin SL-I

The Fujin SL was perhaps the first recumbent to break the 10 kilo barrier, making a really fast competitive, lightweight recumbent a reality for the first time. This was achieved by specifying an entirely new, custom drawn frame tube material, a new seat which is made from 1mm sheet aluminium (the standard seat is 2mm), and then carefully selecting the most effective weight saving components available. The Challenge seat is quite unique and is standard on the basic Fujin. As it is a rigid aluminium frame it is extremely strong, very firmly fixed to the bike and offers maximum support with minimal pressure. Used in conjunction with a filter foam seat cushion it offers the maximum airflow around your back. It is easily adjustable between 25-31 degrees so that as you gain confidence you can adopt a more aerodynamic position. It is available in medium and large sizes to get the most comfortable fit.

Here's how they did it:

  • The SL-Fujin has an aluminium seat and crank boom.
  • The steerer is new: slightly lighter but not pivotting. A pivoting stem is also available.
  • For super-braking-power, there is a totally new centre-spring brake.
  • These figures are the real weight, excluding seat pad and pedals.
