NEW: Protector 19mm ultimate uncroppable hardened boron steel chain (select length below), plus the super-compact RoundLock with both RL21 and RL21A sockets (compatible with 16mm and 19mm chains, respectively). The chain is Sold Secure Motorcycle Gold (in fact, it is Sold Secure Gold in every category) and the RoundLock is Sold Secure Motorcycle Gold/Quad & ATV Gold/Bicycle Gold/Motor Scooter Gold approved. The chain is 6.3kg/metre; the RoundLock combo is another 0.8kg. The chain is supplied with usually bronze colour sleeving, and the chain itself is finished with either zinc plating or a black finish.

3 keys supplied. Keyed-alike available at initial order only (not available retrospectively).

This package includes the standard RoundLock RL21 socket and also the RL21A socket, allowing a beautifully close fit with 16mm and 19mm chains, respectively. The RL21A socket is custom-made to suit the Protector 19mm chain.

The RoundLock can also be used as a motorcycle disc lock - Check that you have a suitable opening that will take the 21mm diameter shackle in your brake disc or disc carrier. You can then use this with a chain when at home and as a disc lock when out and about. Note that disc locks do not prevent a bike from being lifted into the back of a van, which is a common technique employed by thieves.

Price and weight shown are for the package including a 2.0m long chain - Please select alternative lengths below and the price displayed will be adjusted automatically.

The following video gives a quick visual overview of the whole Protector range of chains, from the ultimate Protector 22mm Titan chain, through to the Protector 11mm:

Please note that the Protector 22mm Titan chain shown in the above video has been superseded with a new, even tougher, version. The video will be updated as soon as possible. We apologise for any confusion in the meantime.

Below is a short video overview of the SFB RoundLock, showing how it can be used with our Protector 16mm and 13mm chains and, with the optional RL21A socket, with the 19mm chains:

High quality huge and solid.

- 25/06/2021

I've owned this item a few weeks and being for a new bike I've used it everyday. It fits snugly through the front wheel of my F800R, it also fits through my bike's gap behind the cylinders without issue.
Delivery was great, communication from the suppli...

Huge upgrade to previous security!

- 01/06/2021

Just purchased a high value motorbike which is kept inside a secure garage and wanted to upgrade my existing lock and chain which I use with an underground anchor (a “U” shaped tube that I concreted under the garage floor), as it’s a few years old a...

Great Lock and Chain Combo!

- 19/05/2021

Very good service and best price on the net. Very impressed with both the delivery speed and quality for the lock and chain, definitely will last my lifetime and a big deterrent for onstreet parking/long term parking. Key is a bit of a fiddle to get into ...

Serious Kit

- 03/05/2021

I've had this a while now and felt that it is long enough to give a proper rating of this combo as some locks and chains can end up being fidgety and unreliable. Not these beauties. The round locks themselves are fantastic and handy that they make a good ...

Brilliant product and great customer service

- 23/04/2021

The 19mm chain and roundlock are perfect. Much bigger and heavier than I thought, which will definitely put off any theives. I had to watch the YouTube video to understand how to put the lock on, but once I got the hang of it, it's very simple to use and ...
