Clean, modern style and a versatile, supportive form make the Treble II™ a popular choice for everything from spin classes to centuries. The upper is made of supple synthetic and adjusts quickly and precisely with three wide straps, while an Aegis® anti-microbial EVA footbed keeps you comfortable on longer rides. The stiff, injected nylon outsole is outfitted with our new Universal Cleat Mount system that accommodates both three-bolt and two-bolt cleat/pedal systems.
