C10L wheel offset
« on: April 25, 2018, 03:30:53 am »
This might be of some help.  In trying to solve a tracking problem on my 1954 C10L I stripped the wheels back to the rims and checked offset and runout etc.

Using a straight edge across the brake side of the hubs ( both front and rear) I think offset should be;

Rear hub with sprocket riveted on but no brake plate 1 and 1/8"

Front hub with no brake plate fitted 1/4"

This places the centre of the rear hub on the centre line of the frame and allows a straight chain run to the gearbox sprocket.

When tyres were fitted front and rear and all spacers in place the rims appeared central to the frame centre line. Tyres fell nicely underneath the mudguards.

I couldn't find any actual data to confirm offset and some measuring was done by eye but the bike tracks straight now and doesn't pull to the left anymore.  I'll post a few pics with spoke patterns etc.
