ABUS GRANIT XPlus 540 9-Inch U-Lock - 3.31 Pounds

ABUS GRANIT XPlus 540 540/160HB230 is a compact black U-lock with a dense steel frame and a key cylinder built for bicycle security. Its 9 1/16-inch height and 4 1/4-inch width give the lock a defined working envelope around a frame, wheel, and fixed object.

Steel Construction and Dimensions

The model uses a 13 mm hardened square parabolic shackle. ABUS lists the bicycle version at 9 1/16 inches high, 4 1/4 inches wide, and 43/64 inch in diameter.

The 540/160HB230 configuration weighs 3.31 pounds without its bracket, according to the US technical sheet. That is a substantial carry weight for a bicycle lock, but the steel construction places it in the high-security U-lock category rather than the lightweight commuter category.

Key Cylinder and Mounting

The lock uses an ABUS XPlus cylinder and a key-operated locking type. Its double-bolting mechanism secures the shackle in the lock body, while Power Cell technology is designed to resist impact and pulling attacks.

The package configuration includes two keys and a USH 540 bracket. The bracket mounts to round tubes measuring 15 to 35 mm in diameter, giving the lock a dedicated carrying position on compatible bicycle frames.

Price and Category Context

ABUS USA lists the GRANIT XPLUS 540 with SHB bracket at $174.99 (as of 09/24/2026). REI lists the 9-inch version at $176.00 on its US product listing.

That price places the lock above many basic cable locks and compact U-locks. The trade-off is measurable: the 9-inch model weighs 3.31 pounds, while its internal clearance is suited to standard frame-and-rack connections rather than unusually wide objects.

Best Fit for Secure Parking

The ABUS GRANIT XPlus 540 is a high-security bicycle U-lock for riders who can accommodate a 3.31-pound lock and need a 9-inch locking area. The key cylinder, hardened 13 mm shackle, double bolting, and included bracket define its equipment profile.

Its main limit is physical reach. A 9-inch height and 4 1/4-inch width can restrict connections around oversized posts, broad frames, or multiple bicycles. Riders needing more room can look at the 11-inch 540 configuration, which is a different size and weight.
