Looney SL Adjustable Cage

What Our Gearhead® Experts Are Saying:

"The Looney SL Adjustable Cage has become my default recommendation for anyone who runs multiple bikes or switches between bottle types depending on the ride. The 3-bolt mounting and four height positions give you real flexibility across different frame geometries, and the large dial ratchet is fast and positive enough that you can adjust it without tools in about ten seconds. Double rivets and a serviceable ratchet put this well above anything in the same price range for durability."

Bottle retention is one of those details that only gets noticed when it goes wrong, and the Arundel Looney SL Adjustable Cage was designed to make sure it never does. Built as a larger, more capable evolution of the original Looney Bin, the SL introduces heavier construction and a more versatile mounting system that makes it at home on road bikes, gravel rigs, and everything in between.

The large dial ratchet system is the centerpiece of the design, allowing riders to adjust bottle fit across a 73 to 105mm diameter range quickly and without tools. Four height positions add another layer of adaptability, letting you optimize placement for frame clearance or personal preference, depending on the bike. The 3-bolt mount spacing broadens compatibility across frame types and ensures a stable, play-free connection at the cage base.

Double rivets reinforce the construction at the points of highest stress, and the ratchet system is fully serviceable rather than being a sealed unit that needs replacement when it wears. For riders who run different bottles across different ride types, or who simply want a cage that performs without any second-guessing, the Looney SL Adjustable Cage is the most capable option in Arundel's lineup at this price point.
