Can this be used with a 3 speed Brompton

2017 model

SJS Customer Service:

Hi
Thank you for your enquiry. Yes, this should be fine as long as your bike has the spider type chainset where the rings are replaceable. Depending on the tooth count on your original chainring you will also need to remove links from your chain so that it works correctly.
Kind Regards. JP 11/08/25

I have bought this to fit on a P line 12 speed. Will I need to remove four links from the chain?

Can I use this 40 tooth chain ring with a 12 speed Brompton P line Explore?

SJS Customer Service:

Thank you for your enquiry, yes this will be fine on a P Line however as the chain catcher only has a lowest position for a 44t, it will leave a gap.

Will this 40t chainring be suitable to lower the gears on a 6 speed Brompton C Line Explore (2024)?
