Topeak Bottle holder Tri-BackUp PRO I

This rear rack Topeak Tri-Back Pro I has been specially designed for triathletes, but can be used on any bike! Attached to the saddle rails (vertical and parallel rails at the rear), it allows you to install one or two bottle cages, but also many useful accessories, such as CO2 cartridges, tire bags or tubes. The angle of inclination of the holder can be adjusted to two positions, to suit individual preferences and to make it easier to hold the bottle.
