It’s still fairly uncommon in London to find a bike with chain guards fitted. Yet, they are useful for protecting your clothes and your bike. Hence why they are a common feature on Boris Bikes and pretty much all Dutch style bikes.
You can retro fit a chain guard to your bike. However, it can be a little complicated. Therefore, you may want to opt for using the helmet of a knowledgeable bike mechanic from a local bike shop.
The best option is to choose a full chain case. That completely protects the chain, front chainring and rear cog from the elements, as well as protecting your clothes. However, it’s more likely your bike is equipped for a partial chain case. I outline three good options below.
The Chainboard is a strong yet lightweight option by SKS. Thanks to a universal fitting design, it can accommodate both from and rear derailleurs. It also works with hub gears.
You can get the SKS Chainboard in three different sizes, depending on the number of teeth on your cogs. Installation is somewhat painful, so be prepared to put some hours in if you choose to do it at home.
The downside of the SKS Chainboard is of course the looks of it. There’s no escaping that it’s big, plastic and ugly. However, many people couldn’t care less about this.
It is available from Amazon for around £15.
FreeDrive Chain Cover
The Biologic FreeDrive is a good option for single speed, fixed gear bikes and internal hub gear bikes. It looks a lot sleeker and installation is easier when compared to the SKS Chainboard. It should also go a long way towards protecting your clothes.
The design is unique, in that it moves with your chain.
It is available from Amazon for £19.99.
Another good looking option is by the Herbie Chainglider.
This is designed for hub geared bikes and you must buy the exact size to fit your specific range of ring and sprocket sizes.
Fortunately, installation is easy as it doesn’t require fixing to your frame and you won’t need any special tools. Unfortunately, this does mean that it will rub slightly on your chain but it shouldn’t be noisy.
