Cheers, don’t know if this is any different to the eBay ones but might go for it too as I’m needing a 165 on my Brompton due to my short as legs and rather get shorter cranks than spacers in the seatpost.
In terms of quality I have been running these cranks on all my bikes now for the last few years no probs. Lots of options. In terms of brompton fit I will find out this weekend if bb needs changing to work.
The Brompton BB is a JIS square taper with a 119mm spindle length. The width is important to clear the folded form. A quick glance at your link, and it looks like you'll be okay?
