The Tacx Deva bottle cage is a typically sleek and attractive design, that even in this polyamide reinforced with carbon and glass fiber construction, is very light and strong at 29 grams. Tacx has long made cages with racing cyclists in mind, and the bottle retention on the Deva is perhaps the best the company has ever offered. With an angled, relatively high insert placement, the bottle glides in with minimal effort, with bottle weight resting on the bottom tab, and with a firm tug, the bottle is lifted out cleanly to your preferred side.
