More info

Genuine replacement chain guard for the 50T (standard on 3 and 6 speed Brompton bikes) fixed crank chain ring (pre-2013)

Although the 50 tooth is the standard - it's probably just as well to count the number of teeth on your chain ring to make sure you get the correct size.

Note: The old "fixed" chainset was discontinued in 2016 - so this will probably also be discontinued shortly

It's made of tough plastic - but that does mean that over time it can break. 

The chain guard is held in place with 5 plastic lugs, which when pushed into place secure it to the metal chain ring

This is for the pre-2013 chainring - with fixed right hand crank.

Why discontinued?

It is dissapointing if Brompton have discontinued, it is not a name you sould associate with planned obsolescence.

    Replace chain guard

    I found when hitting the studs they dislodged and had to sand the sides down slightly than that pushed in easily once located finally hit them home with a small hammer

      Good item, bit fiddly to fit, or at least takes a bit of confide

      The old chain guards can get a bit sloppy where the studs insert into the chainring, and of course all that oil only exacerbates the problem of the studs slipping out of the holes. The replacement ring requires you to push or bash the studs, which stand proud on the outside of the disc, into their holes in the chaiguard and into the chainwheel. Of course you don't want to damage the new ring in doing this but it doesn't pay to be too tentative. I find that a pair of molegrips, adjusted to about the right closed gap will give you enough strength to push the studs home. It has a bit more finesse than using a small hammer. Don't be worried if the studs appear to be going in at a slightly funny angle, they will find their way in, straight and true.
