For some strange reason one of the three Gamut chain devices I own doesn't use a 5mm allen key on the lower jockey wheel- its slightly smaller suggesting its an imperial bolt.
Anyone help with what size it'll be so I can get the right size allen key? Not a 4mm so somewhere inbetween..
4.5mm will probably do it then
Like your logic there- but don't have one of those and I'm gussing its more likely to be an imperial size..
3/16ths?
Yup that seems about right, cheers.
If anyone has a spare let me know- nothing else uses that size for me.
My profile imperial cranks have an imperial sized allen key bolt to hold them on. I dont know what size it is in imperial terms, but a 5.5mm allen key works a treat.
r3g are you still after a 3/16" Allen key ?
Please 🙂
r3g mail me your address details and I will post it Sat. (12 hr days tomorrow :cry:)
