Chiru Divider Pinion - Ultra-distance Adventure
Frame Features & Specifications
Designed and developed for the French Divide in 2017, the DIVIDER PINION titanium MTB frame allowed Pierre-Arnaud to cover the 2,200 km of this unique event in France, in 9 days, 12 hours, 52 minutes.
More than 10,000 km without maintenance thanks to the Pinion transmission!
A Pinion transmission was essential to cover the 32,000 vertical meters of the French Divide. This race which connects the Franco-Belgian border to the Franco-Spanish border in total autonomy, required the best compromise between performance, comfort, reliability and luggage loading. The Divider Pinion titanium frame is the result of this demanding goal. The integration of the Pinion transmission eliminates any problems of breakage or maintenance of the gearbox. Thanks to its waterproofing, it is protected from water and mud.
The modern frame geometry fits 3 bottles, bosses for bolt-on top tube bag, Full Frame Bag or Racks and fenders.
While the Divider optimal tyre size floats between 2.0 to 2.4″, the massive frame clearance fits tyres up to 27.5×3.0″ or 29×2.8″ if you decide to add the “+” size comfort to your ride.
The frame geometry is compatible with a Rigid fork or a 100 – 120 mm front suspension fork.
