Bonehead has solved the common problem of where to put your water bottle by utilizing the gear leg weldments in the 7A model to hold cup inserts. (Other models may share the same structure.) The cup holders are contracted in matte finished carbon fiber, and supplied with black anodized aluminum cup inserts - which helps make great use of normally wasted space. Installation is accomplished with supplied Velcro and two zip ties.
Sold as a pair.
