If you live in a hilly area - it's a great upgrade

I recommend this product

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

What speed chain can I use with this Chainring ?

By Raj Mistry

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

SJS Customer Service:

7/8 speed chains would be compatible replacements.

Brompton 44T Chainring

By Hugh Salter

24 Jul 2019

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

Regards

Hugh

SJS Customer Service:

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?

By Brian Heatley

19 Jun 2018

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.

SJS Customer Service:

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

By R Jenkins`

02 Dec 2017

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

SJS Customer Service:

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 neil fields

09 Nov 2017

40 or 38 perhaps

SJS Customer Service:

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.

By Alan Brown

17 Jul 2016

SJS Customer Service:

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 Greg Haigh

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

SJS Customer Service:

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?

By Mikael Fransson

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

br mikael

SJS Customer Service:

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
