Brompton chain

Postby fatboy » 13 Sep 2019, 9:55pm

I'm borrowing a mate's Brompton (2 speed) and it needs a new chain. Brompton do their own chains but is it OK to use a 7-speed/8-speed 3/32 rather than a Brompton bespoke?

yes. IIRC Brompton's own chains are SRAM ones, cut to specific lengths to suit their various models. Presumably if you own a Brompton you can't be expected to shorten a chain like everyone else.

Thought so! To be fair to Bromptons the packaging will be pleasing with old fashioned typed instructions!

I have to shorten any Brompton chain as my chainring is smaller than standard. Not a problem and gives me a few spare links tho’ I have never needed them.

It is very important to get chain length right on a Brompton - but just copy the length from the old chain of course.
