The Robert Axle Project has introduced of a range of aftermarket fat bike axles that will allow riders to attach trailers to thru-axle equipped fat bikes. These new axles will join the company's pre-existing 142 x 12mm axle options.
These replacement fat bike axles are compatible with BOB trailers and hitch-mount style trailers such as Thule, Chariot and Burley child and cargo carriers. All the popular fat bikes models – such as the Salsa Beargrease, Borealis and Trek Farley – are catered for, with four new thru-axle models to suit 12x177 and 12x197 hub standards, with either 1.5 or 1.75mm dropout thread pitches.
All axles are made in Bend, Oregon, USA from a hard anodised 7075 aluminium and stainless steel ends (non fat bike axles pictured)
The Robert Axle fat bike axle was first debuted at Interbike 2014 on the Felt Outfitter bike, an electric fat bike built for hunting, fishing and camping.
Chris Kratsch, president of the Robert Axle Project, said: “The fat bike revolution will allow more people to access more backcountry, all year round. And now, even more functionality is added with the Robert Axles. Dads have the opportunity to bring their kids in a hitch mount trailer, or backcountry hunters can haul their kill out with a BOB trailer.”
The axle is installed or removed with an Allen key
Mountain bike Robert Axles retail for US$56 to US$62. Fat bike axles are a little more expensive, at US$63 to US$69 (UK and Australia pricing is currently unavailable).
