It's Time To Feel BRAVe!
Gravel Bike, Rigid Mountain Bike, Monster Cross, Touring Bike, Back Country or Gravduro. Whatever you want to call it ...be BRAVE!
We wanted a bike to take us back to the core of what cycling is all about. Adventure! Getting out on your bike, not for aero gains or jibbing (no we don’t know what this is either).
Basically, exploring what the world has to offer regardless of the terrain, loading up or just riding because you can and let’s face it there is no better way to see the world than from a bike.
BRAVe 2.0 Flat Bar
BRAVe 2.0 takes the comfort, control and big tyre clearance from mountain bikes whilst bringing the loading capacity, flexibility and efficiency from gravel bikes. The result? An e-bike that can handle all of your adventures.
Vee Rubbers Crown Gem 2.6 tubeless tyres combine excellent all-round, all -weather handling with super low rolling resistance for long gravel roads or loamy single tracks. Durability, serviceability and flexibility are the key words here. Microshift Advent X 10 speed combines the durability of having less gears with the wide range gear ratios of the high end 12 speed group sets. Brakes and hubs come courtesy of Shimano, simple and timeless designs that can be easily fixed on the trail and just about any bike shop in the world will have parts for them.
The Design
The Cairn BRAVe features a balanced geometry that wouldn’t look out of place on either a mountain bike or a gravel bike. Compared to a gravel bike though it’s slacker and longer which brings better stability and control, whilst keeping the steering manageable for the fully loaded days. The shorter seat tubes, taller stack height and 29 x 2.6 tyre clearance increase comfort to almost sofa by the fire levels. The larger tyre width, matched with a more controllable 85nm of torque from the Shimano EP6 system and 180mm disc rotors all combine to keeping you upright and in control on the trail.
Regardless of how you ride or where you ride, the BRAVe has a ton of useful everyday features that make this possible. The semi integrated 630wh external fitted battery is hard to ignore but makes room for frame bags as well as faff free removal and a massive range. Places to mount bottle cages and gear are evident all over the frame. We have 5 different locations featuring 14 bosses to mount all of those big ride needs. Boost hub spacing makes the huge tyre clearance possible and a lowered fork bridge keeps fender compatibility.

The Fastest Wheelset Is The Sum Of The Fastest Parts
Limitless Rims
Wind tunnel developed, features disc-specific, unidirectional T24/30 rims, offering 22.5mm internal and 35mm external widths, and a 48mm u-shape aero profile.
See Full Details
PATENTED LIMITLESS TECHNOLOGY
In order to create the most aerodynamic & stable shape for the tyre, a rim bed of 22.5mm is needed. With the tyre profile this creates, the ideal shape of the rim curves out to an external width of 35mm. To overcome the weight penalty associated with this, we use a (non-structural) low density expanding polymer insert, inside a channel carved out during pre-preg.
This is bonded to the carbon during the curing process, resulting in an exceptionally strong bond. The density of carbon is 1.6g per cubic centimetre, whereas the polymer insert weighs just 0.7g per cubic centimetre, resulting in a (rotational) mass loss of just over 50g per rim. This patented technology enables us to consider the limits of material properties, and smash right past them.
The Details
• Wind tunnel tested, aerodynamically optimised for 25-28c tyres.
• Disc-specific tubeless-ready profile.
• H-lock bead-seat up-kicks for easy and secure tubeless installation.
• Unidirectional T24/30 carbon fibre with 3K weave re-enforced spoke holes.
• Matt black base finished with matt white contrasting graphics.

It's Time to Feel BRAVe
Gravel Bike, rigid mountain bike, monster cross, touring bike, back country or gravduro. Whatever you want to call it ...be BRAVe!
A 21st century take on the touring bike, the BRAVe takes all the great features of gravel and mountain bikes and combines them into one do-it-all bike. We wanted a bike that takes us back to the core of what cycling is all about - adventure! Getting out on your bike, not for aero gains or jibbing (no we don’t know what this is either) but for pure fun.
Basically, exploring what the world has to offer regardless of the terrain, loading up or just riding because you can and, let’s face it, there is no better way to see the world than from a bike.
BRAVe 1.0 Drop Bar
Read More
Ritchey’s super flared Beacon bar provides the controlled feel of a flat bar, with the benefits of having multiple hand positions on long days in the saddle. Maxxis Rekon Race tubeless tyres combines super low rolling resistance, with unprecedented all - surface handling. SRAM's Apex hydraulic group set combined, with their 180mm Centreline rotors, bring high end 1 x specific technology to affordable price points. Combined with 180mm Centreline rotors, the BRAVe 1.0 really does set you on the right path to adventure, both near and far.
The Design
The Cairn BRAVe features a balanced geometry that wouldn’t look out of place on either a mountain bike or a gravel bike. Comparative to a gravel bike it's slacker and longer, which brings better stability and control, whilst keeping the steering manageable for the fully loaded days. The shorter seat tubes, taller stack height and 29 x 2.5 tyre clearance increase comfort to 'sofa by the fire' levels. The larger tyre width, matched with a more controllable 60nm of torque from the Shimano E7000 system and 180mm disc rotors, all combine to keeping you upright and in control on the trail.

This balanced feel means you have the option to run the BRAVe as a drop bar or a flat bar bike. The choice is yours - whether you are a mountain biker looking to get off-piste and explore the areas outside of the bike park or a road, or gravel rider looking for that more capable off-road machine, without losing the sense of speed that you get from being on the drops.
Regardless of how you ride or where you ride, the BRAVe has a ton of useful everyday features that make this possible. The semi integrated 630wh external fitted battery is hard to ignore but makes room for frame bags as well as faff free removal and a massive range.

FAQ's
What is the rider weight limit?
120kg load limit, this includes rider, luggage and weight of the bike. This meets the requirement of ISO 4210 and EN15194. This does not mean if rider and luggage is over this, they cannot ride or buy a Brave. They will just need to be more considerate of the effects this will have on the bike’s lifespan and overall fatigue. You can read more about this in the Cairn Manual.
Can I fit racks?
Yes, the BRAVe has provisions for front and rear racks. On the front we recommend its fixed in at least 3 locations, ideally both fork legs and crown. For the rear we recommend that it is fixed in 4 places, on the seat tube and at the dropout. Always follow the rack manufacturers on max load limits. Alternatively, we would recommend Tailfin or Old Man Mountain Axle mounted racks.
Can I fit a dropper post?
Yes, the Brave has provisions for an internally routed dropper post. The cable needs to run externally on the none drive side of the bike and enter the lower seat tube.
Can I fit a suspension fork?
Yes, the BRAVe features suspensions corrected geometry. This means if you wish you could fit a suspension fork. We recommend between 80 – 100mm of travel.
Is the BRAVe compatible with 27.5" or 650b plus wheels?
Due to the geometry and design of the BRAVe its is not compatible with a 27.5" or 650b plus wheel.
Can I fit cargo cages and how much can they carry?
There is no hard and fast rule on this one. Yes, you can fit cargo cages on any of the bottle bosses provided. We work on a bottle-cage bolt style mount can take about 1.5kg per bolt used. It is dependant on where on the bike its being mounted and how many mounts you use and the kind of things your are trying to carry. We recommend using as many bolts as you can to support the weight the better. So, if you can fit a 3 bolt anything cage this is recommended. Always follow the cage manufacturers on max load limits.
Does the BRAVe have provisions for a kickstand?
Yes, we have an integrated mount on the non-drive side chain stay for a 2 bolt 18mm spaced mount.

The quality of the balls is what determines the performance and lifetime of a bearing. The CeramicSpeed Balls feature unparalleled impact strength, smoothness, roundness and brittleness.
It's Time To Feel BRAVe!
Gravel Bike, Rigid Mountain Bike, Monster Cross, Touring Bike, Back Country or Gravduro. Whatever you want to call it ...be BRAVE!
We wanted a bike to take us back to the core of what cycling is all about. Adventure! Getting out on your bike, not for aero gains or jibbing (no we don’t know what this is either).
Basically, exploring what the world has to offer regardless of the terrain, loading up or just riding because you can and let’s face it there is no better way to see the world than from a bike.
BRAVe 2.0 Flat Bar
BRAVe 2.0 takes the comfort, control and big tyre clearance from mountain bikes whilst bringing the loading capacity, flexibility and efficiency from gravel bikes. The result? An e-bike that can handle all of your adventures.
Vee Rubbers Crown Gem 2.6 tubeless tyres combine excellent all-round, all -weather handling with super low rolling resistance for long gravel roads or loamy single tracks. Durability, serviceability and flexibility are the key words here. Microshift Advent X 10 speed combines the durability of having less gears with the wide range gear ratios of the high end 12 speed group sets. Brakes and hubs come courtesy of Shimano, simple and timeless designs that can be easily fixed on the trail and just about any bike shop in the world will have parts for them.
The Design
The Cairn BRAVe features a balanced geometry that wouldn’t look out of place on either a mountain bike or a gravel bike. Compared to a gravel bike though it’s slacker and longer which brings better stability and control, whilst keeping the steering manageable for the fully loaded days. The shorter seat tubes, taller stack height and 29 x 2.6 tyre clearance increase comfort to almost sofa by the fire levels. The larger tyre width, matched with a more controllable 85nm of torque from the Shimano EP6 system and 180mm disc rotors all combine to keeping you upright and in control on the trail.
Regardless of how you ride or where you ride, the BRAVe has a ton of useful everyday features that make this possible. The semi integrated 630wh external fitted battery is hard to ignore but makes room for frame bags as well as faff free removal and a massive range. Places to mount bottle cages and gear are evident all over the frame. We have 5 different locations featuring 14 bosses to mount all of those big ride needs. Boost hub spacing makes the huge tyre clearance possible and a lowered fork bridge keeps fender compatibility.
FULL SPEC
The Fastest Wheelset Is The Sum Of The Fastest Parts
Limitless Rims
Wind tunnel developed, features disc-specific, unidirectional T24/30 rims, offering 22.5mm internal and 35mm external widths, and a 48mm u-shape aero profile.
See Full Details
PATENTED LIMITLESS TECHNOLOGY
In order to create the most aerodynamic & stable shape for the tyre, a rim bed of 22.5mm is needed. With the tyre profile this creates, the ideal shape of the rim curves out to an external width of 35mm. To overcome the weight penalty associated with this, we use a (non-structural) low density expanding polymer insert, inside a channel carved out during pre-preg.
This is bonded to the carbon during the curing process, resulting in an exceptionally strong bond. The density of carbon is 1.6g per cubic centimetre, whereas the polymer insert weighs just 0.7g per cubic centimetre, resulting in a (rotational) mass loss of just over 50g per rim. This patented technology enables us to consider the limits of material properties, and smash right past them.
The Details
