Details
For 2013 onwards bikes with the spider crankset.

Older, pre-2013 bikes with the fixed chainwheel require an ISO bottom bracket which is no longer available. These will now need to be replaced with a new spider chainset and this new JIS BB


Requires a Shimano type splined bottom bracket removal tool. (Shimano's own is SJSC part #858)

Please note Brompton have selling restrictions to some countries who have their own dealers. If you are unsure please contact our sales team.

Pity that there are plastic screws, I was careful, but it seems not enough because I broke one. So be very careful with them.
Watch Out You'Ll Probably Need A 20-Pin Bb Tool

I recommend this product
Consonly problem is information on website
Buyers should be aware that the unit shipped is not the one shown on the photo. The photo shows a Bottom Bracket compatible with a 6-notch bottom-bracket tool (e.g. Parktool BBT-4). Instead I was shipped one with a 20-pin arrangement (compatible with e.g. Parktool BB-32): this appears to be Brompton's latest standard unit. You may need two different Bottom Bracket tools to change this part depending on what type you have already. SJS, please update the info here.

Hi,

Thank you for bringing this to our attention, Brompton had not informed us of the stock change so we were not aware. We have now updated the image and description to match this new design. We apologise for any inconvenience this may have caused.

Best Regards.

Enquiry About Brompton Bottom Bracket For Spider Crankset
By
24 Jan 2017
Hello,

I have a doubt regarding the bottom bracket used with the "new" spider crankset. According to your website, the one to use is your part #31207, which is compatible with a 20-pin-arrangement bottom bracket tool (such as Parktool BB-32). However, I´ve noticed Brompton stock bikes keep coming with a 6-notch-type bottom bracket even though they have the spider crankset. Do you have any idea why or what bottom bracket is that?

Thanks a lot in advance.
Hi,

For the last few years this has been the bottom bracket Brompton has offered as a replacement for the spider type chainsets. They are now swapping back to a 6-notch type but we have still got a number of this splined version in stock. Other than the fitting type the bottom brackets are identical.

Thanks.

This bottom bracket is the correct replacement part for your 2015 Brompton, the tool for fitting is the same as a Shimano internal style bottom bracket tool. These are SJSC part number 858.

Hi, I have a pre2013 brompton. Can I upgrade with this BB & the spider crankset without problems? (ie, thread on the frame compatible, etc)
Hi,

You shouldn't have any problems upgrading your bike with this bottom bracket and a spider chainset.

Thanks.
Is This Bottom Bracket Suitable For Pre 2013 Bromptons?

Hi,

No, this one is specifically for the spider cranksets, you need the other Brompton bottom bracket SJSC part number: 31610.

Thanks.
