Where you going that carrying a spare split link won’t do?
The Motion Pro jumbo tool is ok for doing the DiD chains, it comes with the pin for doing the hollow pins. The quad stake pin is an option but it’s for solid pins, the DiD chains I’ve got on the bikes are hollow (please check though


) so I was ok with the pin it came with.
Flared perfectly to the spec, I would advise that flaring it is the same as cutting a bit of metal… you can cut a bit off but can’t cut a bit back on.


Take it gently until you get a feel for it, can always give it another nip… but if you over flare it it’ll be too tight and you can crack the end of the pin if you make a cnut of it.
As me how I know…

Botched the rivet link on mine so I’ve got a 520VX3 with a VT2 split link


and a perfectly riveted 520MX on the mrs bike.
Buy spare pins too, they’re not readily available in you damage one.
