Cairn E-Adventure 1.0 2021

Cairn E-Adventure 1.0 2021 Press Release:

Always wanting to improve the Cairn team took the award-winning E-Adventure back to the drawing board to see how it could be improved further. Being devoted riders ourselves and listening to our existing customers allowed us to change small things that have a big impact overall.

Things like cable guide positioning to clean up the lines as well as re-positioning the Fazua remote for easier control.

Bigger changes come in the form of the gravel-specific GRX groupset from Shimano, braking from the hoods has never been so comfortable as well as confidence-inspiring.

Increasing stand over on the frames has done a huge amount for off-road control and manoeuvrability, it also has opened up our bikes to smaller riders. The shorter seat tube will increase the amount of seat post being used to give more flex and comfort over the previous frame.

Staying with the frame, the rear seat stay bridge has been removed to increase frame compliance, there is now a single-sided plate for mounting mudguards – which can be removed for ultra-clean lines. The E-Adventure’s geometry stays the same though, so the quick, capable and confident handling that has won it so much praise is still there.

New Cairn specific Hunt E-Gravel Disc Wheels increase longevity with a steel axle to deal with the increase in torque as well as the freehub having a bigger surface engagement at the pawls.

Recent updates (Black Pepper Fazua Update) to the Fazua system have seen better control and usability for the rider, the ability to connect to most 3rd party computers now gives the rider dual-sided power meters – something that would normally leave a hefty dent in your wallet. Cairn has also used this new functionality to create a specific “Cairn” tune to get the most from the Fazua/E-Adventure bike, this can, of course, be tailored by the rider or set back to “standard” settings easily in the software.

With the recent move to range extension battery’s the Fazua systems batteries are just over 1kg, this coupled with the Cairn Battery keg and Blackburn cage means you can easily carry another full battery.

700c or 650b

Gravel is such a broad term, and we realise this, one riders gravel ride is another’s mountain bike ride. This is why we came to the conclusion we needed two versions to give choice to the rider; we have the fast-paced 700c perfect for tarmac commutes with the ability to fly up the towpaths or farm trails for an adventure. If you like your gravel to be more chunky or the destination for your ride is an MTB trail then the 650b version has you covered with big volume tyres supplying grip as well as comfort and the dropper post gives you the room to move when things point down.


The 700c version comes equipped with the fast Hunt X Cairn E-Gravel Disc wheels which features Hunts Gravel X Wide rim profile and are laced to a 4 pawl, 36 point engagement E-Bike specific hub design. Mounted on these are Vittoria’s awesome Terreno Dry tyre in 700x38c. Giving you the perfect balance of fast paced road and trail exploration. Ritchey components supply the cockpit matched with a carbon seat post to increase comfort on rougher trails or for removing road buzz. All finished off with Fabric’s excellent bar tape and bum friendly saddles. Not forgetting both bikes come ready with mounts for guards, racks and anything cages


The 650b version is ready for the more rowdy rider, if you want to take the more rugged path or even the odd trail centre then this bike is just the ticket. Using the same E-Adventure frame it comes equipped with 650b Hunt Adventure Sport rims on Hunt E-Gravel hub. Tyres are supplied by Vittoria again with the Mezcal 2.25” front and 2.1” rear tyres, the mix in sizing is something that the MTB fraternity have been doing for years and makes total sense on the front for better grip, more comfort and control. It also comes equipped with a Tranz-X dropper post (80mm drop) with drop bar remote, to allow easier weight shifts and control on steeper terrain, the remote can be easily accessed from the hoods or the drops.

Both Bikes will be available worldwide.
