Hollowtech II Rigidity. Pro-Tier Power Transfer.

The engineering core of the Shimano 105 FC-R7000 Crankset is its Hollowtech II technology. By forging hollow aluminum crank arms, Shimano maximizes arm rigidity and structural integrity while shaving away crucial weight. The integrated 24mm steel spindle and outboard bottom bracket design widen the bearing stance, greatly reducing frame flex under load so that every watt you put into the pedals goes directly to turning your rear wheel.

Why the Shimano 105 R7000 is the Smart Rider's Choice:

  • Hollowtech II Forged Aluminum Arms: Hollow-core forging balances maximum mechanical stiffness with a remarkably low weight profile.

  • Asymmetrical 4-Arm Spider: Inherits the iconic 110mm Asymmetrical Bolt Circle Diameter (BCD) layout of Dura-Ace. This places structural reinforcement exactly where the highest pedaling forces occur during your downstroke.

  • Optimized Chainring Spacing: Specifically redesigned for modern disc-brake road and gravel frames. The increased clearance prevents chain-rub when running wider rear hub spacings (135mm / 142mm) and short chainstays.

  • Durable 24mm Steel Spindle: Integrates seamlessly with widely available, reliable Shimano Hollowtech II bottom brackets for smooth, friction-free rotation and simple, tool-friendly maintenance.

  • Aesthetic Integration: Available in a sleek, anodized Silk Black or classic Spark Silver finish, blending beautifully with any modern carbon or classic steel frame design.

The Alegro Perspective: While Ultegra and Dura-Ace save a few grams by using carbon-reinforced components, the 105 R7000 offers virtually identical power transfer and shifting accuracy. It's incredibly resilient to daily abuse, and the 24mm steel axle standard is legendary for its reliability. If you want a setup that performs day-in and day-out on the asphalt without babying it, this is the best dollar-for-performance crankset on the market.

Rigid Mechanical Efficiency. Proven Durability. Drive Your Ride with Shimano 105.
