Shimano SLX CS-M7100 10-45 12速飛輪

The 10-45 range gives me exactly the climbing gears I needed without losing top-end speed. Shifting is crisp and the weight savings from the spider construction are noticeable on the trail.

Installed this cassette last weekend and the BEAM SPIDER construction really does make it noticeably lighter than my old one. Shifts are crisp across the entire 10-45 range, even under load. Exactly what I needed for my trail setup.

The beam spider construction really does trim some grams compared to my old cassette, and the 10-45 range gives me just enough for steep climbs. Shifting feels crisp, though I did have to tweak the B-screw adjustment a bit more than expected.
