Others lean too heavily into retro nostalgia. The ROLLCii 13 sits somewhere in between — clean, classic, and practical without feeling like a copy of anything from the past.\u003c\/p\u003e\n\u003cp\u003eThe shape is simple for a reason. A traditional 5-bolt crank still makes sense today: durable, easy to service, and widely compatible.\u003c\/p\u003e\n\u003cp\u003eBuilt around the classic BCD144 track standard, the ROLLCii 13 is designed for riders who appreciate straightforward function and timeless proportions. The wide chainring stance and traditional bolt pattern remain a proven choice for fixed gear and track setups, whether built for daily riding, velodrome sessions, or steel track bike projects.\u003c\/p\u003e\n\u003cp\u003eEach crank arm is made from cold-forged aluminum alloy, then carefully polished by hand to achieve a smooth and refined finish. The result feels timeless rather than flashy — something that works equally well on a steel track bike, a clean fixed gear commuter, or a classic pursuit-inspired build.\u003c\/p\u003e\n\u003cp\u003eThe ROLLCii 13 isn’t designed around trends. It’s simply a solid crankset with good proportions, useful standards, and a shape that still looks right years later.\u003c\/p\u003e\n\u003ch3\u003e\u003c\/h3\u003e\n\u003ch3\u003eSpecification\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMaterial: Aluminum\u003c\/li\u003e\n\u003cli\u003eAxle: JIS Square Taper\u003c\/li\u003e\n\u003cli\u003eChainline: 43mm ( Spindle:107 or 110mm)\u003c\/li\u003e\n\u003cli\u003eBolt Circle Diameter ( BCD): BCD144\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eNote:\u003cbr\u003eBoth 107mm and 110mm spindle lengths share the same drive-side dimensions.
