102 links 1/2" x 3/32" and PowerLink - made by SRAM
This chain is suitable for a standard 2 speed Brompton bike (with a 54 tooth chainring) or a standard 6 speed Brompton bike (modified to a 54 tooth chainring).
Note: if your chainring is smaller you would need to remove links (e.g. if changed from 54 to 50 you would remove two links and from 54 to 44 you would remove 4 links)
Brompton chains are available in 4 different lengths:
96 links - normally used on a 3 speed with reduced gearing
98 links - normally used on a 3 speed with standard gearing
100 links - normally used on a 6 speed with standard gearing (also for 3 speed with increased gearing or a 2 speed with reduced gearing)
102 links - this one - normally used on a 2 speed with standard gearing (or a 6 speed with increased gearing)
To remove your old (non quick link) chain and re-install this new one you will need a chain tool such as the CT-3 from Park Tool or equivalent
To remove an old chain which does have a quick link - a pair of chain link removal pliers can be very helpful
