Arundel STR Mandible Sideloader UD Matte-Right Seat Tube Mount

A sideloader bottle cage for the rider on a compact-frame road bike or full-suspension MTB where the seat tube and top tube fight for bottle real estate, the Arundel STR Mandible Sideloader in UD matte carbon loads from the right and uses Arundel's Mandible grip profile, the strongest in the lineup and proven on the MTB World Cup circuit.

Full carbon construction holds claimed weight to roughly 25g, and two pairs of mounting holes spaced 20mm apart let you drop the cage lower on the seat tube to clear a frame bag or fit an oversized bottle. The right-hand side entry means you tip the bottle out to the right rather than lifting clear of the top tube, a setup that solves the cramped-triangle problem without sacrificing retention.
