KIBO DIRT DROP TRANSMISSION
We only use proven touring specific Shimano components for our Kibo drivetrain - they’re durable, designed for touring with spare parts available around the world.
The excellent 10 speed Shimano T-551 triple 24-32-44 chainset combined with the Deore 11-36 cassette provide a great gearing range for all terrain and hills with loaded panniers. The gear range is a massive 617% with 17 (1st gear) to 104 gear inches (30th gear).
The T551 is our favourite expedition chainset - it’s basically the same as the old XT 9 speed triple chainset we’ve used for the last few years, as that’s no longer available this is the natural choice as the highest spec triple compact Shimano chainset. If you don’t require such low gears then the XT T8000 26-36-48 chainset (which we use on the Skyelander) is also an option. The 'T' in T551 and T8000 denotes the fact that this chainset has been specifically designed for touring versus M which are MTB by design.
We also use a high spec bottom bracket - the Shimano XT MT800.
The front Deore and rear Deore XT rear derailleurs deliver smooth and reliable shifting across the 30 gears.
The shifting is through Microshift bar-end shifters, a friction shifter controls the front chainwheel and a 10 speed friction/index shifter controls the rear cassette.
