27.01.19 / Turner Cyclosys Gravel CX

Turner Bikes, a US mountain bike company steeped in history (anyone remember the original Turner Burner?), has decided to step into the cyclocross market with its new Cyclosys.

Drawing on the company's mountain bike expertise, the new model features a 1,430g (3.15lb) aluminium frame with disc brakes, thru-axles and space for 43mm tyres.

The new Turner Cyclosys has a more organic background though, and came about because founder Dave Turner says he rides and races cyclocross during the winter, really getting into it over the last few years. 

“In the 30 plus years I’ve been in mountain biking, I’ve seen the sport and the racing scene evolve and change over the years,” says Dave Turner. “Some for better, some for worse.
What I experienced at my first CX race in 2010 reminded me of the “good ol’ days” of MTB racing: a great sense of community and camaraderie, and a good dose of competitiveness.”

The frame is designed for disc brakes, there is no rim brake version. The rear post mount on the chainstays has been designed in such a way to avoid the necessity for adapters.
To provide the necessary tyre clearance the rear stays are asymmetric, the non-driveside chainstays fattened out to 24mm.
There's a PressFit30 bottom bracket for additional stiffness. Turner says this approach provided the necessary tyre clearance, good for 43mm gravel tyres, yet keeps the chainstays short for nimble handling and stiff for optimum power transfer.
