Cairn has released a new version of its gravel adventure e-bike, the E-Adventure 1.0 Rambler Edition. Cairn has made a number of updates that bring it in line with the best electric gravel bikes including new geometry, bigger wheels, and lower weight.
Cairn says that it has applied a touch of the ‘Lower, Longer, Slacker’ treatment to the geometry, taking inspiration from the mountain bike-orientated Cairn BRAVe. The 70-degree head angle and 74-degree seat angle aren't particularly radical, however, the slammed 80mm of bottom bracket drop is unusual. Cairn says this has been done for two reasons, not only to maintain a stack height with a manageable saddle-to-bar drop but also to improve handling confidence and make the bike more fun to ride.
There have been a few other frame tweaks too. Cairn has opted to spec 700c wheels only, rather than the 650b spec of the older Cairn E-Adventure, and there is clearance for 45mm tires. A lower top tube increases standover and should allow a little more seatpost flex. Smaller tube diameters have been used in the rear end and top tube to reduce weight and add more compliance to the frame. More significantly though, Cairn has answered the call of shorter stature riders and introduced an extra small size. There's also routing for a dropper and plenty of bosses for mounting bikepacking bags, mudguards, or racks.
While Cairn doesn't offer a build with a suspension fork, instead speccing a full carbon fork with Triple Anything mounts on both legs, they say the E-Adventure 1.0 Rambler Edition is compatible with 30-40mm travel and should have a 40-45mm offset to maintain the bike's handling.
Considering you are getting a motor-equipped bike, the reasonably competitive $4,935.61 / £4,289 / €5,000 ($ price subject to exchange rate) priced E-Adventure 1.0 Rambler Edition has an impressive spec sheet.
Cairn has specced Fazua's lightweight Ride 50 Street Drivepack motor, which has an output of 58Nm of torque and is controlled from an integrated Fazua touch remote in the top tube.
The bike comes with Campagnolo's 13sp Ekar gravel groupset and a Hunt x Cairn X-Wide E-Gravel wheelset fitted with fast-rolling Vittoria Terrano Dry 38mm tires. It's finished with Cairn's Adventure bar and stem and a carbon seatpost. Cairn claims that the full bike including the motor and battery weighs 14.3kg (size medium), which is pretty impressive considering the bike has an alloy frame.
The bikes aren't available quite yet but can be pre-ordered at Cairncycles.com , you shouldn't need to wait too long either as delivery is expected in December 2022.
