Packed with features for safe cycling, the Cygolite Hotshot Micro combines a powerful 2 watt LED with 5 road-proven modes and an Enhanced Cycling Optic™ that spreads light at a wider angle for maximum distance and extra wide visibility during night and day use. New Versatite™ lets you attach the Hotshot Micro 2W™ tail light to most seat posts and seat stays, including aero styles.
This WILL FIT ON TT SEAT TUBES!
