Review SHIMANO 105 Speed Hydraulic Groupset

The Shimano R7100 105 12 Hydraulic Groupset is a premium component system designed for road cyclists seeking a balance of performance, reliability, and affordability. This groupset is part of Shimano's 105 series, which is known for its high-quality components at a mid-range price point.

The Shimano R7100 12-speed cassette offers a wide range of gears, from 10-34 teeth, ensuring smooth pedaling and efficient power transfer across various terrains and gradients. The rear derailleur, R7000-GS, is designed with a Shadow RD technology, which reduces the risk of chain slap and improves shifting accuracy.

The Shimano R7100 105 hydraulic brake system features dual-pivot calipers for superior stopping power and modulation. The brake levers, R7020, are ergonomically designed for precise and comfortable braking, even in extreme conditions. The brake fluid used is DOT 4, which provides excellent heat resistance and longer service life.

The crankset, R7000, is available in both 50/34T and 52/36T chainring configurations. It features Hollowtech II technology, which reduces weight and increases stiffness for optimal power transfer. The crankset is also compatible with Shimano's SM-BSR61 Hollowtech II bottom bracket, ensuring a secure and efficient connection to the frame.

The Shimano R7100 105 12 Hydraulic Groupset is built to last, with durable materials and precise manufacturing processes. The shifters, R7100-SS, are designed with a 2-way release mechanism, allowing for quick and precise shifting even under heavy load.

In summary, the Shimano R7100 105 12 Hydraulic Groupset is a complete and high-performance component system that caters to the needs of serious road cyclists. It offers a wide range of gears, powerful and modulated braking, and a stiff and efficient crankset, all wrapped in Shimano's reputation for reliability and durability.
