Our opinion

Bruno V.

Road specialist

The Shimano 105 Press-Fit BB86 bottom bracket (ref. ISMBB7141B) is an essential component for road cyclists looking for an excellent balance between performance, reliability and durability. Part of the Shimano 105 range, it benefits from proven technologies to ensure smooth, efficient pedalling on all types of terrain.

Designed for PressFit BB86 standard frames (41 mm in diameter, 86.5 mm wide), it ensures perfect integration and increased rigidity of the crankset. It is compatible with Shimano Hollowtech II systems with 24 mm axles, offering optimum power transmission and improved efficiency.

Its high-quality bearings, combined with effective sealing, reduce friction and provide lasting protection against water, mud and dirt. The result: increased longevity and consistent performance, even during intensive use on the road or in difficult conditions.

Highlights:

  • Shimano 105 range: performance and reliability
  • Standard PressFit BB86 (41 x 86.5 mm)
  • 24 mm Hollowtech II axle compatible
  • Fluid bearings with low friction
  • Reinforced seals for improved durability
  • Ideal for road, endurance and intensive training
