Shimano Tiagra Triple Chainring Bike Crankset 175mm

The Shimano Tiagra FC-4703 Crankset delivers responsive power transfer and versatile gearing tailored for serious road cyclists navigating varied terrain or demanding conditions. Engineered around a lightweight yet rigid aluminum frame finished in durable gray anodized coating, this system combines corrosion resistance with optimized stiffness via its integrated 24mm axle design—a configuration that reduces rotational mass while enhancing pedaling efficiency under high torque loads such as steep climbs or sprints out of corners.

Designed specifically for modern road setups featuring disc brakes requiring over 415mm chainstays—such as those using 135/142mm disc hubs—the FC-4703 integrates seamlessly into contemporary bike builds while maintaining backward compatibility with traditional 130mm rear hubs when needed. Its asymmetric chainring arrangement pairs triple rings (50/39/30T) across dual BCD patterns (outer ring at asymmetrically spaced 110mm / inner at asymmetrically spaced 74mm), ensuring precise shifting across a wide gear range ideal for everything from technical mountain passes to fast-paced group rides on open roads.

The hollow-forged cranks feature Shimano’s Hollowtech II spindle interface (9/16″ pedal spindle), balancing strength-to-weight ratios favored by competitive riders while adhering to industry standards—though note this model requires purchase of a compatible bottom bracket separately due to its press-fit design philosophy prioritizing upgrade flexibility over one-size-fits-all solutions.

With its compact geometry delivering an ergonomic Q-factor of precisely 158.8mm paired to standard-length cranks at industry-standard 175mm lengths, this system strikes an ideal balance between aggressive racing demands and everyday ride comfort—making it equally suited to weekend endurance adventures or training sessions pushing mechanical limits without compromising reliability over thousands of kilometers of use.Crank length availability may vary by region; verify sizing before purchase.*
