Makes a huge difference on the hills. Effectively, you're trading in some of your top speed for a greater ability to climb.

Can I replace my stock 50T chainring without changing the spider arms on the crank?

Thanks,

Thanks for your enquiry, yes it fits straight onto the standard spider chainset

What speed chain can I use with this Chainring ?
By
10 Jul 2020
I'm planning to use one of these chainrings on a non-brompton.

Can I use this with a 10 or 9-speed chain ?

Thanks
7/8 speed chains would be compatible replacements.

Is this compatible with a 2019 model Brompton and is it possible to purchase it without a chain guard?

Regards

Hugh
Hi there,

Yes, it is compatible with your 2019 Brompton. Unfortunately, we do not have any without a chain guard I'm afraid.

Thanks.
lower gears on a brompton?

Do you stock a 38 teeth or even lower chainring that will fit a Brompton Spider arm? This one won't get me quite as low as I would like.
Hi there,

Any of our 130mm BCD 5 arm chainrings should work fine. However we have never tried this so we cannot say for certain.

Thanks.
Use with other cranks

Can this be used with another 130 BCD crank arm, and will it run a 3/32 chain?
Thanks
Hi,

Yes these chain rings can be used with other non Brompton cranks and they use a 3/32 chain.

Thanks
hi, is there a smaller chain ring that will fit the brompton 2013 onward spider
By
09 Nov 2017
40 or 38 perhaps
Hi,

As the Brompton spider uses the standard 130BCD sized fitting there are plenty of aftermarket options that would fit and work. The only downside with the aftermarket options is that they won't have the chainguard. The one we recommend is SJSC part number 11055.

Thanks.
Will I Have To Reduce The Chain Length To Change From 50T To 44T.

Hi,

The chain will need to be reduced by two links to be the correct length for use with a 44T chainring instead of 50T.

Thanks.
Make It Easier To Pedal Up Hill?
By
04 Jun 2015
I have a 2013 Brompton with 6 Speed Standard gears. I just want to confirm that this is the chain ring I need to make it easier to ride up hill? Will I need to adjust the length of the chain too?

Greg
Hi,

To gain a lower gear all you need to do is run a smaller chainring like this one. If you are dropping to a 44T ring on a 6spd then you will require a chain that is 98 links long.

Thanks
Does This Fit On The Following Bike?

Brompton Chainring Guard for Spider Crank 44T on a Charge Grater 2.

br mikael
Hi, unfortunately this will not fit the Charge Grater 2 as the chainset BCD is different. The Brompton chainring needs to fit to a crankset with a 130mm BCD, the Charge crankset has a BCD of 110mm so they would not be compatible. Regards, Jamie
