Race XXX Lite

Information from: http://bontrager.com/model/06393.

At an insanely lightweight 17 grams, this unidirectional carbon fiber cage weighs so little you'll hardly know it's there; that is until you reach down and easily remove your securely-held water bottle. Recommended for use with small (591ml) water bottles and on-road use only.

Features

Bontrager's lightest seat post

High strength full carbon head
