Product Details

Overview — hardened 9mm steel chain and ABUS XPlus technology

Abus Steel-O-Chain 9809K XPlus is a premium chain lock built for riders who want serious theft deterrence without complicated installation. The 9mm square chain links, the chain housing and the locking mechanism's structural parts are made from specially hardened steel to resist cutting, sawing and leverage attacks. The lock uses ABUS's proven XPlus cylinder for high pick resistance. The unit also includes an automatic keyhole cover that keeps water, grit and corrosion out of the cylinder so it keeps working across seasons. Choose from four lengths — 85cm, 110cm, 140cm and 170cm — so you can secure a single frame or loop around a post and wheel for maximum security.

Key features and construction details

Robust materials and smart engineering. The chain's square links are heat-hardened and tempered steel for extreme shear and bolt-cutter resistance; the textile sleeve prevents frame scratches while giving the lock a clean black finish. Internal lock parts are reinforced with hardened steel inserts to protect against drilling and prying. • 9mm hardened square chain for high resistance to cutters and saws. • ABUS XPlus cylinder offers superior pick and bump protection. • Automatic keyhole cover protects the cylinder from dirt and corrosion. • Textile sleeve shields paint and reduces noise when carrying or locking.

Fit, sizes and carrying tips

The Steel-O-Chain 9809K XPlus is available in 85cm (2.8'), 110cm (3.6'), 140cm (4.6') and 170cm (5.6') lengths so you can pick the right balance of reach and weight. The 85cm is ideal for locking a road or commuter frame to a post and is the lightest, while the 170cm gives plenty of slack for looping through both wheels and around a larger anchor. Note: this model ships without a mounting bracket. We recommend storing it in a pannier, backpack, saddle bag, or using a universal bracket accessory if you want on-bike carry. With a 9mm thickness and heavy-duty construction, this chain is best transported off-frame or in dedicated luggage for comfort.

Who it's for — commuters, urban riders and high-value bikes

If you ride in an urban environment where opportunistic theft is common, or you own a high-value road, commuter or e-bike, the Steel-O-Chain 9809K XPlus is a top choice. Its hardened-steel construction and XPlus cylinder give serious protection compared with cable locks or lightweight chains. This lock is also a great option for short-term stops — cafes, shops and public transport hubs — where visible heavy-duty security deters thieves. Riders who prioritize minimal weight for racing or long bikepacking rides should consider lighter alternatives for on-the-bike carry and reserve this chain for staged security at stops.

Frequently Asked Questions

How secure is the ABUS XPlus cylinder?

The XPlus cylinder is one of ABUS's top-rated lock cores, offering excellent resistance to picking, bumping and drilling. In real-world terms it significantly raises the skill and time required for a thief to compromise the lock compared with standard cylinder designs.

Which chain length should I choose?

Choose 85cm for compact stops and lightest weight, 110cm or 140cm for general urban use, and 170cm when you need to loop both wheels and the frame around a solid anchor. Consider how you plan to carry the chain — longer links add weight and bulk.

Does the lock come with a mounting bracket?

No, this model does not include a bracket. Abus and third-party universal brackets and carry solutions are available separately. Many riders carry the chain in a pannier, backpack or dedicated lock bag for comfort.

Will the sleeve damage my paint?

No — the chain comes with a durable textile sleeve designed to protect your frame from scratches. Still, avoid dragging the chain across delicate finishes and check the sleeve periodically for wear or embedded grit that could abrade paint.

Is a 9mm chain heavy?

A 9mm hardened chain balances security and portability — it's heavier than thin cable locks but far more protective. Exact weight varies with length; consider shorter lengths if minimizing carry weight is a priority.

Can I register the lock or get replacement keys?

ABUS offers key replacement and code registration services depending on the key code supplied with your lock. Keep your purchase info and key code safe; contact ABUS or Forest Bikes customer service for guidance on replacement keys.

Buying Guide

When choosing a chain lock, prioritize material hardness, lock cylinder quality and the length you need to secure both frame and wheels. Hardened-steel square links at 9mm thickness provide a strong balance between cut resistance and manageability; pair that with a high-security cylinder like ABUS XPlus to deter lock picking and drilling attempts. Consider how you'll carry the lock and where you'll leave your bike. Longer chains give flexibility for awkward anchors but add weight — if you travel light, opt for a shorter length and complement it with a secondary cable or U-lock for the wheels.
