Hi folks,
I have an all-chrome Sun Worksop frame just like grumpycommuter's:
http://www.retrobike.co.uk/forum/files/dscf5382_182.jpg
and want to fit a classic Raleigh Heron cottered crank to it, like this one:
The problem is that the bottom bracket spindle that came with the frame is too short for this crank - it bottoms out on the fixed cup too far out to fit the cotter pin.
So, which spindle do I need, and does anyone have one? None of the three spindles I have will work. The BB shell seems to be a standard Raleigh 26tpi model at ~70mm width.
The supplied spindle is about 126mm and has the Raleigh stamp and '16 P' marked on it. As I said, the drive side is too short and the crank bottoms out to far to insert the cotter pin.
I have a longer Raleigh spindle at about 141mm but it must be for a far wider shell, since the bearing shoulders are further apart and on the non-drive side it sticks out too far to engage the adjustable cup. This one is marked 'RAL. PA' and ' Made in Eng'.
The third one seems to be just the right length at 135mm but the spindle is fractionally thicker than the others and so I can't mount the cranks! This one is marked "TDC C 5'
I'm sure I'll eventually find the right spindle, but I'm even more sure that engaging the great minds on here will make the job easier! Any of my current three spindles are available as a potential swap.
Cheers,
Gareth.
