The Shimano TL-FC20 is a super useful little tool that most people don’t realise they need. One end is slotted to perfectly fit the back of a chainring bolt and the other is a pair of spaced pins for installing or removing Shimano dust caps, and also works with a lot of other dust caps including those on self-extracting crank bolts too. As if that wasn’t enough it also has a 4 mm and a 9 mm socket. Nicely made by Shimano and cheap enough to have just in case, and light enough to carry with you.
