Sneak Peek: Ultralight & Versatile Tune Hollow Carbon Cranksets w/ Single Chainrings
Tune’s working on a new carbon crankset that’ll be among the lightest available and offer plenty of adaptability for various frames and chainring sizes.
Built around their “Smart Spindle System” design, which is essentially a long 30mm spindle, it’ll work with their bottom bracket fitting BSA, Italian, PF30, BB30, OSBB for Specialized, BB86, BB90, BB92, FSA pressfit and 386 EVO. What’s new are the hollow carbon fiber arms that will become the premium offering above their alloy Smart Foot road and mountain bike cranks. The alloy spider shown here is also new, with a 76 BCD to fit SRAM XX1 chainrings…or these new Tune single rings.
Pics, weights and more colors below…
The spider and bolts will come in a range of color options to match Tune’s existing catalog.
Word from Fair Wheel Bikes is that the spider is removable, letting you swap in the 110/130 BCD road bike spiders and 104/64 or 120/80 mountain bike double and triple spiders. Their new single chainrings will be available in even numbers from 30 to 38 teeth.
Claimed weight is just 360g for the crankset, which includes arms, spindle, spider, lock ring and lock nuts. But, they say that doesn’t come at the expense of performance, saying their layup gives it an excellent stiffness to weight ratio. Pricing and more info TBD.
