non low profile cranks used an approx 122mm bottom bracket axle cooks brothers for example
where shimano stx were approx 110mm low profile
now if you use a bottom bracket mounted front mech does it sit further in than a clamp on front mech
i have some v brakes somewhere they have the stud an spring plate still attached
seems like someone loctited the bolts an they have unscrewed from the forks instead of the brake boss
