I think there is a dedicated tool for these, but I just use a small adjustable pin spanner bought on ebay for about a fiver.

mmm ta, I tried my pin spanner (didn't know it was called that until now) that I bought to fit a royce BB but the pins are too big. I can't find any on ebay with pins less than 4mm, except a £60 one :?

I can't remember where I bought mine or what exactly they were called :?

I think someone on here sent me a link, so there might be a thread somewhere... will have a look if I get a minute!

I used the park tools one ? spa2 ? for my similar ones, or there is often prongs on a chainring bolt tool as I found out.

There is also a green with slightly larger pins.

Just checked the chainring bolt tool I have. Luckily no prongs or I'd be kicking myself now. Parktool on it's way via trusty old ebay.
