I have an old Raleigh Banana. Shop standard,
??? Let's see it.. Post some pictures .
40/49 double dates it a while back.. perhaps a whole new chainset? to get a bigger difference.
a 5 bolt 110 bolt circle, lets the small chainring be a 34t
I have a riveted together 52/36 combination for old 3 arm cranksets, fitted to 70's Peugeot's.
so scrounging in older bike shops storage bins has some findings there, too..
