100 link Brompton chain

Brompton 6 speed chain with 100 links (1/2" x 3/32") - and SRAM PowerLink for easy connection of the chain

We recommend that if changing your chain you also change the sprockets at the same time

Chain compatibility:

This chain fits the following 16 inch Brompton models:

Standard 6-speed Brompton (SRAM or Sturmey Archer BWR rear hub) - with 50T front chain ring - so standard C Line 6-speed gearing
2-speed / urban (12/16T with reduced gearing 50T front chain ring)
13T 3-speed with a 54 tooth front chainring
14T 3-speed with a 54 tooth front chainring

Note: if your chainring is smaller you would need to remove links (e.g. if changed from 50 to 44 you would remove two links) - or purchase a QCHAIN098DR - 98 link chain

If your chainring is bigger your would need a chain with more links (e.g. if changed from 50 to 54 teeth you would need two extra links - giving a chain length of 102 links - QCHAIN102DR - 102 link chain)

This chain is NOT compatible with the following Brompton models:

C Line / C Line Electric 12-speed
P Line / P Line Electric
G Line / G Line Electric
T Line

Tools Required:

To remove your old chain and re-install this new one you may need a chain tool such as the CT-3.3 or CT-5 from Park Tool or a pair of master link pliers

Installing the new chain will be easier as it comes with a SRAM PowerLink

Brompton chain length summary:

Chainring	One Rear Sprocket		Two Rear Sprockets
54 tooth	12 or 13t	100 Links	12/16t, 13/16t or 13/15t	102 Links
50 tooth	12t or 13t	98 Links	12/16t, 13/16t or 13/15t	100 Links
44 tooth	12t, 13t or 14t	96 Links	12/16t, 13/16t or 13/15t	98 Links

Purring again

While a little disappointed to have to replace within the year after average mileage, change and spare part/s were at least not that expensive and Brompton is back to its best again. Thank you Mike and Brilliant Bikes again for great service.

Excellent Service

I bought this along with a chain tensioner and rear sprockets. I ordered the wrong sprockets by mistake but they swapped them straight away, no fuss. Highly recommended.

Excellent service as usual

Like others here I bought the chain along with a replacement set of rear sprockets. As I do quite high mileage on my Brompton P6 this is an annual job. Total time taken for the swap is about an hour- made easier by the "powerlink" Don't risk replacing the chain without the sprockets-- I did this in the past and then suffered chain jumping until I realised the cause of the problem. These part wear faster on a Brompton c.w. a normal bike as everything is closer to the ground and thus more likely to collect dirt. Brilliant Bikes service excellent as always!

Great Service

I've had a few of these from Brilliant Bikes over the years and they always arrive the next day. I was a bit suspicious of the PowerLink but have never had any problems with it coming loose. When I take off the old chain I just use a chain punch as normal rather than trying to find the PowerLink.

Excellent quality and service as usual

I bought this along with two sets of sprockets for a BWR hub. Both products arrived quickly and in good order. I was even supplied with a pair of plastic gloves which were put to good use. This chain came with a power link connection, this is the first time I have tried one with this chain size (I have been using them for years on my 9 speed road bike). No problems with transmission and the postage and packing was also free. I also like the personal touch with the hand drawn smiley sun on the invoice.

Thank you Brilliant Bikes
Lynn
