The key to the pedaling experience.
Description
The new Super Record Wireless Cassettes were conceived, studied and designed to guarantee cyclists with the smoothest shifting across the entire range of combinations.
For this reason, closer jumps are key to the pedaling experience of all cyclists, who are always guaranteed perfect cadence in any situation.

The three new 10-25, 10-27 and 10-29 cassettes embody excellence in the search for performance, lightness and durability.

Smooth shifting is guaranteed by single-tooth jumps up to the seventh gear, and especially in the second half of the cassette where jumps are a maximum of three teeth between one gear and the next.

Devised and designed from scratch, the new Super Record Wireless cassettes mount the N3W freewheel body present on all new-gen Campagnolo road wheels. The N3W is very versatile, with the same groove profiles as the classic Campagnolo freewheel body, but lighter and 4.4 mm shorter.
Characteristics
Perfect cadence: the SUPER RECORD WIRELESS new gear combinations enable fast up- and down-shifting, with an extremely smooth fluid gear inch ratio, to guarantee constant cadence in any situation  
Resistant to wear and tear: thanks to the use of special steel and processes with minimum tolerances, the cassette has been designed to be durable and resistant  
N3W Freewheel Body: the new cassettes are to be installed on the N3W freewheel body, present on all Campagnolo new-gen road wheels  
Same-thickness spacers: easy to fit without any risk of error
