"Why has this not been done before?"
We get used to hearing that. It's not the first time a simple idea has been overlook (like our tubeless wingnut). Having raced on the track in the late 90s and early 2000's Boyd Cycling founder Boyd Johnson has seen a lot of track wheels. While working on a new track wheel lineup, a simple thought came to mind, "Why don't we attach the track cogs like rotors?".
Cue up the centerlock track cogs. Designed to fit on the same centerlock spline as a disc brake rotor, changing gears between races has never been easier.
At the heart of these wheels is a clever new hub design – the CL-TK hub uses a centerlock spline and cog for a much simpler and extremely secure interface. Simply slide the cog on the hub, tighten the disc rotor lock ring and you are good to go. Cog changes between events have never been simpler. The flip-flop hubs are also threaded for a standard cog and lockring so you can use your existing collection of cogs.
"We feel the centerlock track cog is a much faster and easier method for a track cog interface. Almost every track rider we have spoken to has accidentally cross-threaded a track hub once resulting in needing a new hub."
Available in 14 tooth through 19 tooth, the centerlock track cog represents the next generation of what track hubs should be.
