The Cinch Carbon is about shedding grams without sacrificing function. At 16 grams, this is Blackburn's lightest cage, designed for riders who track every ounce on their bike. The minimalist profile uses just enough material to do the job—hold a bottle securely—and nothing more. If you're building a lightweight setup or just want to stop thinking about cage weight, this is where you land.

The uni-directional carbon fiber layup provides strength where it's needed while keeping material use to a minimum. The open design allows easy bottle insertion and removal, but the grip is firm enough to keep bottles planted on rough roads or during hard accelerations. The matte finish matches modern carbon frames without drawing attention, and the construction is stiff enough to maintain its shape under load. Blackburn lab-tested this cage specifically for bottle retention, so it's not just light—it holds on.

The Cinch mounts to standard two-bolt cage bosses and works with most standard-diameter bottles. The cage shape provides clearance for both traditional round bottles and bottles with contoured shapes. Blackburn backs this cage with a lifetime warranty, which covers defects in materials and workmanship. If you're after the lightest cage that still functions reliably, this is it. The weight savings adds up when you're running two cages, and the carbon construction means you're not compromising durability to get there.
