Ian Austen, Bicycle Makers Struggle to Swat Down Counterfeits. New York Times, July 21, 2015 (in the Sports section).
Note:
(a) "a bicycle made by Specialized"
Specialized Bicycle Components(, Inc) https://en.wikipedia.org/wiki/Specialized_Bicycle_Components
(founded in 1974 by Mike Sinyard and is based in Morgan Hill [in Santa Clara county], California)
(b) "Maria Adams, the brand protection manager for SRAM, a bicycle-parts maker based in Chicago"
SRAM Corporation https://en.wikipedia.org/wiki/SRAM_Corporation
(a privately held bicycle component manufacturer; founded in 1987; SRAM is an acronym comprising the names of its founders)
(c) "To make high-end racing helmets, the authentic versions of which can cost nearly $300, companies like the California-based Specialized and Giro mold some of their helmets around expensive composite roll cages to reduce weight without compromising strength. Because the roll cage is invisible to buyers, counterfeiters simply omit it, resulting in a substantial price difference: Knockoffs of the Giro Aeon helmet, which sells for about $200, can be found online for $50."
(i) Giro (company) https://en.wikipedia.org/wiki/Giro_(company)
(a manufacturer of helmets [among other things]; founded in 1985 by Jim Gentes and is headquartered in the Scotts Valley [in Santa Cruz county], California)
(ii)
(A) roll cage https://en.wikipedia.org/wiki/Roll_cage

(B) That is for a car. What about a helmet?
