Gravel Specific Drivetrain

HUNT X Cairn E-Gravel Disc Wheels
Developed specifically for the Cairn E-Adventure Rambler with a steel axle and increased pawl contact area for a longer lasting hub. The wide 25mm internal Gravel X Wide rims offer better tyre profile and allow for lower pressures, increasing traction and comfort.
Multiple Mounting Points
Whether you’re commuting to work or tackling an all-day gravel adventure, the multiple mounting locations allow you to fix racks, guards, and bike bags.
Shorter Seat Tube
For the E-Adventure Ramber, the shorter seat tube allows for additional flex in the seat post, increasing comfort and stand over clearance.
Introducing Campagnolo Ekar; born on the mountain that gave the groupset its name. Cima Ekar is a charmingly diverse little gravel paradise in the Venetian Pre-alps. Ekar is a gateway to adventure, offering a test of skill, technique and fitness. The mountain and region begs to be explored, with networks of broken roads, single track and trails pointing off in every direction.
The Ekar group set imbodies everything that has become synonymous with Campagnolo. It’s the lightest Gravel groupset on the market, while still durable with heat-treated carbon steel and nickel-chrome-satin surface treatment.
The groupset’s 13-speed 10 – 44 tooth cassette offers the widest mechanical gravel gearing range on the market with the smallest jumps between gears, an attribute that riders will appreciate several hours and several mountain passes into their ride.
The HUNT X Cairn E-Gravel Disc wheels have been developed specifically for the Cairn E-Adventure Rambler and feature a steel axle and increased pawl contact area for a longer lasting hub. The wide 25mm internal Gravel X Wide rims offer better tyre profile and allow for lower pressures, increasing your traction and comfort. Like all HUNT wheels, they are tubeless-ready.
Fast, agile and offering confidence to push hard in the turns – this is what a good tyre should feel like.
Vittoria have the know how, they are one of the largest bicycle tyre manufactures in the world and the design and development that goes into the tyres is astonishing. The Terreno Dry is the perfect choice for the Rambler and features 3 compounds (with added Graphene) to deliver ultimate performance in a straight line and corners alike.

For the Rambler, we continued to partner with the team at Fazua and spec their Ride 50 Street Drive Pack.
Its integration and natural pedal feel were exactly what we were looking for to complement our bikes. At only 4.6kg for the full system, it helps to create an incredibly lightweight and nimble e-bike. Furthermore, the system has no mechanical resistance if not in use, meaning you can choose to ride it as a normal/analogue bike without any drawbacks.
Choose from three levels of assistance or pedal without any help at all:
Breeze (~100 watts*)
Gentle constant. Like a strong tailwind even at low rider power.
River (~210 watts*)
Progressive and very sporty mode, for a smooth riding experience! The strength of the support precisely follows your own power. Give a lot - and get a lot from the motor.
Rocket (~250 watts*)
Aggressive assistance that helps you to tackle the very steepest climbs. This one will put a big grin on your face!
Ride 50 Street Drive Pack
Fazua’s all-new Ride 50 Street drive pack takes the original Evation system to the next level. The new drive pack features increased torque output, now putting out up to 58Nm of torque, helping tackle those technical or steep climbs. New cooling fins are present to manage system temperature.
The Ride 50 Street bottom bracket unit sees the biggest changes, with new torque and cadence sensors increasing the sensitivity of the unit by 70%. This will allow the system to further smooth out that natural ride feel that the Fazua Evation system has become known for.
The Energy 250x battery brings the final flourish of details to the build. The 250x offers the capability to turn your bike on and off from the remote (mounted in the top tube).
A new cap on the charging port adds a nice touch and reduces maintenance in the future.

Ebiketips 4.5/5 Review
"If, like me, gravel riding has always been a bit of a question mark, then I urge you to go and try out one of these Rambler’s on a dusty trail. The handling, the comfort, and most importantly, the fun I experienced atop this bike was game-changing."
2020 Cycling Weekly Editor's Choice
"The E-Adventure 1.0 is an incredibly likeable bike to ride. I can be pretty on the fence when it comes to e-bikes, preferring like many for my legs to be the main performance delivery system for my riding. But after the first ride I came away with the same sense of rewarded effort as if I had ridden a ‘normal’ gravel bike – but one that I managed to ride farther than my legs felt like they had ridden."
Cycling News Recommends 4.5/5 Review
"Cairn has taken the already somewhat niche electric gravel bike concept, sprinkled a little adventure dust on it and come up with one of the most versatile e-bikes around."
Move Electric 4.5/5 Review
"The Cairn Cycles E-Adventure is an electric gravel bicycle designed and tested on British landscapes. Definitely a bike that makes you want to explore.."
Cyclist Magazine Review
"A well considered e-gravel bike that now offers a choice of wheel configurations."
Singletrack Charged Full Review
'They produce products that they want to use, and the Cairn is a product of that: it’s a bike to replace a car, go to work the long way round, and throw in a bit of weekend adventure.'
Featuring all-new geometry, the Rambler Edition aims to bring the rider more control without taking away the lively and responsive feel our bikes are known for.
The steeper 74-degree seat tube angle allows for better climbing on rough terrain, giving you a more efficient pedalling position, whilst maintaining all-important rear wheel traction. Combined with the slacker 70-degree head angle and increased 75mm trail, coming back downt the hill is a more predictable, stable and comfortable, experience, empowering the rider to let off the brakes and push the bike further.
The net result of the geometry changes is a riding position that puts the rider more in the bike than perched on top, achieved by increasing the bottom bracket drop to 80mm whilst maintaining a stack height with manageable saddle-to-bar drop.
The Rambler is the first Cairn E-Adventure to be compatible with suspension forks. If you ever do decide to add a suspension fork to your E-Adventure, we would like to make some recommendations based on our own testing:
- - 30-40mm of Travel
- 40-45mm Offset
- 700x45c (or larger) tyre
- If possible, upgrade to a larger front 180mm rotor
- 12x100mm spacing (keeps compatibility with stock wheel)
