Is a chainring bolt spanner absolutely necessary, or can i bodge it with a screwdriver across the slot? How tight do they actually need to be? Don't really want to spend cash if I don't need to.

Great, that's what I wanted to hear. My LBS would have definitely done it for nothing but has somewhat disappeared :smile:

I have used a slotted screwdriver to hold the hollow bolt in place whilst I turned the allen key.

Didn't realise there was a special tool .... but then I wuold have made my own. probably.

Screwdrivers are ok if you can get one with a wide enough blade i.e. much wider than most domestic screwdrivers. If it's too narrow you just chew up the heads. OTOH if like mine the other part of the stackbolt is an Allen-slot, you can do all the work with an Allen key and just hold the slot with something like a table knife.

TBH I prefer to have the proper tool, if it's cheap enough. Just like it makes me shudder to see people using adjustables instead of having a proper set of spanners.

I have one exactly like that. I bought it out of desperation with some really stuck bolts. It works, but not so well designed because as you can probably tell from the photo/scale it is very small and hence offers little leverage. Mind your knuckles if you end up using one!

I splashed out £3.49 on that tool in the end. Leverage / reach was no problem with a single cog, job done.

I'm a real cyclist! :laugh:

There's only one bike with bolts that need it, the others will nip up and tighten with just the allen key.

The older I get, the faster I used to be ...
I've got a CNW-2, am I a real cyclist too? Just find it makes life easier. (N.B. you use the tool to hold the nut firm, the allen key to undo/tighten.)
