Plasticine Tool or indestructible chain?
Followig on from this thread:

I have fitted the links to my Shimano 10 speed chain however in doing so I had to do this to my chain tool:
Basically the pins would not move without brute force and the helping hand of a spanner to give me more leverage.
The pin in the 9 speed chain just popped out with much less effort.
Why the difference?

Which chain was it exactly?0

If it's any consolation that was my experience the first time I tried to break my 10 sp 105 chain! Bent my trusty old Halfords chain tool like a banana. It had been dealing with 8 speed mtb chains for years.
I think the tolerances must be so much tighter in the manufacture of narrow 10 speed chains; I've observed that pushing out a pin, when you eventually manage it, shaves off a tiny bit of metal. Presumably this is part of the reason you can't reuse them.
I now use KMC joining links rather than faff with Shimano joining pins.
God knows what will happen if I ever need to break the chain using the tiny thing on my multitool :shock:0 -
The pins on modern 10-speed chains are held far more securely - the ends are peined-over to stop them coming-out. This means your chain tool needs to exert more force to release them - you tool is made from mild-steel and not strong-enoughMake mine an Italian, with Campagnolo on the side..0

Not plasticine then? :roll:
Ta. Didn't know (beforehand) that there was a difference between 9sp and 10sp.
I'd hate to have tried to do that at the roadside. In fact I couldn't have as the spanner was a necessary.
Any suggestions on a replacement which will still fit in a saddle bag?0 -
Park Tool CT-5 is tiny (easily fits in a saddle bag) and works fine on 10-speed, I have used it several times on Shimano 105 / Dura Ace and Ultegra 10 speed chains - never a problem with bending / lack of leverage.

Monty Dog's hit the nail on the head. If you have a look at the pin you managed to get out you'll see what he means.0
