The Shunan Road Bike Crankset is a clean, reliable, and highly budget-friendly replacement crank layout designed for road bikes, fast urban commuters, and sports hybrids. Featuring a standard compact/semi-compact spider structure and double-ring profiling, it delivers efficient power transfer and clean mechanical chain guidance for daily training and utility riding.
Key Technical Specs:
Chainring Combination: Double 52/39T layout (52-tooth outer ring for top-speed flat-road sprinting; 39-tooth inner ring for comfortable climbing cadence).
Bolt Circle Diameter (BCD): 110mm (Standard 5-bolt configuration, making it highly customizable for replacement rings later).
Crank Arm Length: Standard 170mm aluminum alloy arms for balanced torque distribution and optimal ground clearance.
Axle Interface Type: Square Taper (JIS) layout. Threads smoothly onto standard budget-friendly square taper bottom brackets.
Average Weight: ~815g (Total mass including left and right arm assemblies with pre-mounted chainrings).
Drivetrain Compatibility: Optimized for standard 8, 9, and 10-speed road chains and matching road front derailleurs.
Product Highlights:
Rigid Alloy Construction: Crank arms are forged from lightweight, durable aluminum alloy with a clean satin black finish, keeping the build highly resistant to flex under hard pedaling.
Removable/Serviceable Rings: Unlike cheap, pinned, one-piece steel alternatives, this unit features a bolted chainring system using standard 5-pin hardware. Rings can be swapped individually if they wear down or if a different tooth ratio is preferred.
Integrated Shifting Gates: The steel outer chainring incorporates precision ramp stampings and shifting pins on the backside layout to guide the chain cleanly and rapidly during heavy front derailleur shifts under load.
Pricing & Availability:
Price: 3,500 KSh
Condition: Brand New / Pristine assembly (includes right drive-side crank arm with rings, matching left-side crank arm, as pictured).
These are excellent value options for riders replacing stripped pedal threads or worn-out factory cranks.
