One of the main protagonists of the new SRAM Eagle (not to say the main one) is the new 10-50 12-speed cassette.
The XD core continues to be used, so no special adapter will be needed. The number of teeth in the first eleven crowns are the same as those of an 11-speed cassette (10-12-14-16-18-21-24-28-32-36-42). The distance between crowns has been slightly adjusted to make room for the new 50-tooth sprocket and it is slightly closer to the spokes (2 mm to be exact) than the previous 42 of the 11-speed cassettes.
The declared weight for the new 12-speed cassette is 355 grams (87 grams more than an 11-speed XX1) and has been built using X-Dome technology, where nine of the crowns are machined from a single piece. The rest of the sprockets are made of steel, except for the 50 that is made of aluminum. Tooth carving also undergoes slight changes, seeking better chain retention.
The cassette manufacturing technology SRAM provides great durability with the lowest possible weight.
The new features generate a smoother, quieter system that improves the performance of changes, both up and down.
The SRAM brand is a company with 25 years of a history marked by the tenacity, innovation and constant progress that have led it to become the second world referenceof cycling activities in a very short time.
