So, in keeping with the period look, I’ve opted instead for a set of ‘springer forks’. Hopefully that’ll soften the ride in style.
There seems to be a lot of variation here, the steerer tube length, OD, ID, and thread length being rather important. Quite a few phone calls, emails, and a bit of umming and arring and hopefully I’m good to go.
Length: 8”, OD:1”, ID:7/8”, Thread length 3”.Wheel in, and fotunately all seems to line up nicely with the front Sturmey Archer hub. Brake arm fits nicely, might need a bit of gentle persuasion when the tyre goes on. Hmm, the steerer tube has got a step at the base, and the lower bearing track on the headset doesn’t fit. Back to the machine shop.
