What size spanner for rear gears

rubez

Unfortunately my rear gears takes a spanner instead of an allen key, and I only have a large adjustable spanner, which is far from ideal.

So, anyone know the size of spanner I need, so I can get a small spanner with a ring side to easily tighten the cable in it?

Thanks.

You need a 5litre spanner for that

Not sure which bolt your are talking about, the cable clamp bolt? Just measure across the flats of the bolt, it will be 8mm, 10mm or 13mm I would guess.

The bolt that tightens down on the gear cable (after you tension it)

I ordered a 4th hand to make things easier, so I want to avoid using an crappy adjustable spanner.

How hard do you want to hit it? Large spanner to hit hard, small spanner to hit less hard.
Alternatively buy a spanner set and see which one fits?

Fuck it, I'll just use the adjusty.

Course you will

Of course any sensible person would check it with the shifting spanner and measure the gap.

No need even for Parktools, which hasn't been mentioned yet.

9mm on low level Shimano mechs....oddball size for those who are used to cars where you'll only ever get 8 or 10mm.

It's a special weighted spanner you need. Your local bike shop will have one, ask them for a long weight and you will get exactly what you need.

Just go single speed or get a unicycle , , maintenance will be easy even for you.

Are you some sort of inbred? Have you already got three hands?

Obvious. But they are listed as third and 4th hands for some reason. Just about pointless for gears but OK for Vs, which rubez claims to have as disks are shite.
