Hello,

Since the handlebar on my six-speed Brompton is a bit busy…



… I'm thinking of replacing the original derailleur shifter with either of those found on eBay:

• https://www.ebay.fr/itm/263181978927
• https://www.ebay.fr/itm/222637391838
• https://www.ebay.fr/itm/263331380833

Has someone tried any of those ?

Thank you.
