Anyone know the max sprocket for a Simplex Juy 51? 24, 25?
As I've mentioned above, the TdF mech struggles to get onto a 22 sprocket, although a 23 is said to be possible. I'd guess the JUY 51 is probably a bit better (no direct experience). I think it was a weakness with all those pull chain mechs which go into bottom with the cable slack
If you're mainly going to ride round London Airport, or you're a strong climber used to riding round the Chilterns on fixed, 46 x 22 would be fine, otherwise I'd be thinking about the possibility of a smaller inner ring, probably TA Cyclotourist.
It's one of the mysteries of 1950's bike racing - how did they manage to get up those climbs with bottom gears not much under 60".

I’m planning gearing for my Gillott.

I need to buy a 5s freewheel 14-whatever the mech will get on to.
Probably going to have 49/46 on the front.
