The Sabbath mountain bike brand hails from the same people who produce Sunday Bicycle road bikes, and the Fifth Element is their first foray into the mountain bike world.
Dubbed as a ‘mountain biker’s mountain bike’, this titanium frame was created in response to requests from Sunday Bicycle’s current road bike retailers who were keen for the company to produce a titanium mountain bike. The Fifth Element has been through the prototyping, testing and tweaking stage, and is ready for launch for 2009.
The titanium is twice heat treated, once after tube production and once after the frame has been assembled.
Final versions are expected to be available in the UK in three sizes (16, 18 and 20inch) by the autumn.
- Top tube: Squared from round section design. This process stiffens the material slightly. It is also double butted and has an extended top tube.
