Shimano 105 FC-R7000 Crankset – 170mm Road Bike Compact Gearing Black

Shimano 105 FC-R7000 Road Crankset
Engineered for precision and endurance, the Shimano 105 FC-R7000 crankset delivers seamless power transfer for competitive cyclists and weekend warriors alike. Its double-chainring configuration (50/34T) optimizes gear ratios for climbing efficiency and sprinting agility on mixed terrains.

Key Innovations:
– Hollowtech II Spindle: Reinforced alloy construction reduces rotational inertia by 15% compared to standard designs while maintaining torsional rigidity for explosive acceleration.
– 410mm Chainstay Clearance: Wider 11-speed chain spacing prevents rubbing on compact frames (135mm O.L.D.) without compromising stiffness ratings tested at 2,500N lateral force
– Modular Compatibility: Works with both traditional 130mm road hubs and* modern 135/142mm thru-axle systems (chainstays >415mm)

Performance Metrics:
| Specification | R7000 | Competitor Avg |
