Product Details

Overview & Technology

Abus Yarnit 4004C blends hardened-steel security with a soft textile sleeve to protect your bike's finish while delivering dependable theft resistance for urban and road environments. The 24mm chain profile offers a solid compromise between weight and cut resistance, while the 110cm length gives plenty of reach to secure both wheel and frame to fixed objects. Inside the sleeve you'll find a tightly assembled, specially hardened steel chain designed to resist common attacks with bolt croppers and hacksaws. The lock uses a convenient, user-set combination mechanism so you never need to carry a key — a practical choice for commuters and riders who value simplicity and durability.

Key Features

Built for everyday security: the Yarnit 4004C combines robust materials and thoughtful construction to protect bikes in high-risk urban areas. Key features focus on real-world usability—length, protection, and ease of use. • 24mm hardened steel chain: thick, high-tensile links for improved resistance to cutting tools. • Protective yarn sleeve: soft, abrasion-resistant cover prevents paint chips and scratches and reduces noise while riding. • User-set combination: convenient keyless locking that’s easy to reset and share with trusted riders. • 110cm reach (also 85cm variant): long enough to secure frame and wheel to most posts, racks and railings. • Multiple colorways: available in Black, Denim Blue, Midnight Purple and Sand Stone for a personalized look.

Fit, Length & Compatibility

The standard 110cm (43.3") length gives you the flexibility to loop through both frame and rear wheel and lock to many street furniture types. A shorter 85cm (33.5") version is available if you prefer a lighter, more compact carry option. The chain's diameter and flexible links make it easy to thread through tight spots, spokes and around angled posts. The lock is universally compatible with road, commuter and hybrid frames; carry it in a pannier, saddlebag or clipped to a bottle cage mount with a gel or nylon strap. Because the sleeve protects paintwork, it’s also a strong choice for carbon frames and finished alloy bikes where surface protection matters.

Who It's For

The Yarnit 4004C is aimed at riders who need reliable, everyday theft deterrence without the inconvenience of keys — commuters, city cyclists and road riders who lock up in short to medium-term urban situations. It’s a practical option for those who balance security with portability. If you regularly leave your bike unattended in very high-risk locations for long periods, consider pairing the Yarnit chain with an additional anchoring solution or upgrading to a heavier, higher-security chain or U-lock rated for maximum resistance to determined thieves.

Frequently Asked Questions

Is the Yarnit 4004C keyless?

Yes — the Yarnit 4004C uses a user-set combination mechanism so you don't need to carry a key. The combination can be reset by following the manufacturer's instructions included with the lock.

Will the yarn sleeve protect my bike's paint?

The soft textile sleeve prevents direct metal-to-paint contact and reduces abrasion and chips while locking and transporting. The sleeve also cuts down on clanking noise when the chain moves.

Is 24mm thick enough for high-theft areas?

A 24mm chain offers solid resistance to casual thieves and is a strong deterrent for urban parking and short-term stops. For long-term parking in high-risk locations, consider supplementing with a secondary lock or choosing a higher-rated, heavier chain or D-lock.

Can I secure both wheel and frame with the 110cm length?

Yes — the 110cm (43.3") length is designed to loop through the frame and rear wheel and still reach many street posts and bike racks, making it practical for securing both in one pass.

Are replacement sleeves or parts available?

Replacement sleeves or specific spare parts depend on local Abus service policies. Contact Abus support or your Scenders customer service for guidance on spare parts and warranty options.

How should I carry the chain on my bike?

Carry options include stashing the chain in a pannier or saddlebag, attaching it to a rack or mounting it with a third-party strap or holster. Choose a method that keeps the chain secure and prevents rubbing against paint.

Buying Guide

When choosing a chain lock, balance length, thickness and portability. Longer chains (110cm+) give you more flexibility to secure both wheels and the frame, while thicker links (20mm+) increase resistance to cut tools. Consider whether you prefer keyless convenience (combination) or keyed cylinders for different security profiles. Match the lock to your parking habits: short urban stops usually require less heavy-duty protection than unattended overnight storage. Pair a Yarnit-style chain with a smaller U-lock or secure anchor for layered security where theft risk is high.
