Reduce the gearing (make going up hill easier) by changing from a 50T (standard on 3 or 6 speed) or changing from a 54T (standard on a 2 speed) to this 44T!
The Brompton "Spider" crankset was introduced on new Brompton bicycles at the beginning of 2013
This is a replacement 44 tooth chain ring complete with chain guard
One of our most popular upgrades - allows a Brompton with 50T c chain ring (standard gearing) and spider crankset to be changed to reduced gearing - making going up hills easier
It can be used to replace the 44, 50 or 54 teeth chain rings on the "spider" crankset introduced in 2013.
A standard 3 or 6 speed Brompton comes with a 50 tooth front chain ring - changing to 44 teeth will reduce the gearing by approx 14%

Great service, product and videos
Purchased this item to help me cycle up local hills. I included a new compatible chain but I made the mistake by ordering the wrong chain however this error was picked up by Brilliantbikes before it was shipped and they sent me the correct chain. Delivery was quick and included latex gloves.
The 44T has made a big difference to me. Before this modification I needed to stop and push my Brompton up my local hills but now I can manage them without stopping.
The video by Hannah are very helpful and the process of removing and installing was made very clear. 10/10
Great service and quality item
Quick delivery and quality item, hills are much easier now with a loaded bag on front.
Nice handwritten note on the invoice too
Well worth it for hilly regions
I changed my 50 tooth for this 44 tooth chain ring and found the hills (finally) were not so difficult. Tip: There is the Park Tool Chain Ring Nut Wrench CNW-2 which helped me torque the bolts properly. Without this tool I couldn't torque things properly.

Good conversion for extra low gears
As other reviewers, a doddle to fit. As the chain ring nuts weren't seized didn't need a chain ring nut spanner. The two redundant links easily removed with a chain link extractor.
Still enough high gearing on the 6 speed Brompton for me (you need to be going some to spin out) and makes the climbs more achievable.
Great service from Brilliant Bikes and a great web purchase experience.
Good for the old knees!
If your knees are getting on a bit then you will be wanting one of these! Takes about 5 minutes to change over. Makes hills a good deal easier. Do yourself a favour and buy the matching chain to save having to shorten your existing chain by 2 links.
Designed for Cumbria
As someone riding a Brompton out of it's natural city habitat, the 44T chainring has made it easier to say in the saddle on many a Cumbrian climb.
Shortly going for a ride over some alpine passes where I'm sure this will come in handy too.
Great service from Brilliant Bikes and simple to fit and shorten chain if you have a few basic tools.
