New in box Recon lightweight machined steel (single piece monoblock) cassette in 12-27 for Campagnolo 11 speed. They are made of long wearing hardened steel yet due to extensive machining they weigh nearly 100 grams less than a similar sized Chorus ( 279 grams and $ 140 typical cost) and over 40 grams less than a similar sized Record cassette ($2 85 typical cost). Fits onto Campagnolo compatible hubs for use with Campagnolo shifting systems. Includes the Campagnolo version aluminum lockring. This cassette in 12-27 is very hard to find. Most sellers have cassettes with 11 tooth first cog. Recon also makes cassettes for Edco and several other small brands Cogs have a finish that is titanium color.
