Further to earlier post - can't remeber which topic it was...
Some later bantam swinging arms are different to earlier ones...
They are I think the same length 15.062" to the shortesr availble setting.
Looking throught my parts books D7 has two kinked arms.. D10 a kinked drive side arm and a straight right arm,
D14s sports68 kinked arm and a D175 a straight arm. But gap between arms for the wheel and brake etc are the same.. So anyone wanting to run a fatter tyre should opt for the straight arm type- slightly more options availble....
