Turner launches into cyclocross with new Cyclosys
Burner also updated plus fresh 27.5+ Sultan configurations
After years of requests, Turner Bicycles is finally jumping into the cyclocross scene with the new Cyclosys, featuring a TIG-welded aluminium chassis and lots of liberally shaped tubing. Also coming from Turner is a refreshed Burner trail bike and the second coming of the Sultan 29er, which can now be had in 27.5+ flavours.
Turner may be late to the cyclocross party but the Cyclosys looks like it’ll hit the ground running with thru-axles front and rear, disc brakes, and clearance for 43mm-wide tyres (claimed) despite suitably stubby 425mm chainstays. At least for now, both thru-axles stick with the currently standard 142x12mm and 100x15mm dimensions. Meanwhile, a PF30 bottom bracket shell will leave sufficient room for an aftermarket eccentric should anyone want to go with a singlespeed setup.
The Cyclosys will mark a series of firsts for Turner, too. In addition to it being Turner’s first-ever non-suspended frame, the Cyclosys will use more liberally shaped aluminium tubing than usual, including a flattened top tube underside to help lessen the sting of shouldering, a flared seat tube for added drivetrain stiffness, and asymmetrical chainstays to boost tyre and chainring clearance without having to resort to a machined yoke.
While other Turner frames use external cable routing, the Cyclosys will also instead go fully internal with convertible aluminium ports to accommodate a wide range of drivetrain and brake configurations. Especially interesting is how the front derailleur cable pops out of the frame through a port on the backside of the seat tube above the bottom bracket shell. This not only allows riders to use standard bottom-pull derailleurs but should also collect less grass and debris than traditional setups that route the cable underneath the shell.
The internal cable routing setup can be configured for a number of different drivetrain and brake setups
Geometry is definitely on the modern end of the spectrum with 65-70mm of bottom bracket drop, depending on size, and a comparatively slack 70-72 degree head tube angle for more stable cornering.
While Turner generally manufactures its frames in the United States, the Cyclosys will instead be built overseas.
