What is particularly noticeable in terms of evolution with the R8100 generation is the grip comfort and brake control of the ST-R8170.
The bracket shape feels very natural, giving the impression that your hands will not tire easily even during long rides. The brakes are also easy to control from the moment you grip them, providing a sense of security even on descents or in wet weather.
The shifting response of Di2 is, of course, excellent, and the feeling of precise shifting the moment you press the lever is something you won't want to give up once you've experienced it.
This latest generation ULTEGRA STI lever is recommended not only for race-oriented riders but also for long-distance riders who prioritize comfort and operability.
