For Sale:  One gently used Lazer Chrono 3 TT helmet, size large (53-59cm).  I have had this helmet for several years, but have only used it for a couple triathlons and at most a dozen time trials.  It has always been cleaned and stored in its bag after every use.  It features "turnfit" retention system that makes the helmet comfortable and top venting to keep your head cool.  The helmet has the original US CPSC sticker that is required by USAT.  First $50 gets to take her home.
