The rear hub on the 1957 basket case I bought is knackered, so bought a bantam d1-d3 hub which is meant to be the same. All the dimensions are all the same apart from the spoke mounting plates gap, my old hub is 2" and bantam is 1 3/4 " . Will this 1/4 make a difference? Did the colts from 1954-56 have the 1 3/4 " gap, draganfly list only one grease seal from 1957-58 .Is this due to the gap widening to 2" ? Can any Colt owners measure the gap and let me know. Cheers michael
I suspect you might run into a problem with the hub offset, i.e. where the rim sits in relation to the face of the hub when the wheel is in the machine.
I think it would be a good idea to mount that hub in your frame and see if you can get the rim in approximately the correct position, with that spoke flange 1/4" further over - the spoke angles are very shallow on the rear wheel of a Bantam.
What size is the colt rim? The Bantam rim is a 19" WM1 with 36 spokes; The spoke lengths will be different using a Bantam hub on a Colt, I suspect.
