So I am trying to replace my pitted front axle cones, but struggling to find the parts of the right size.
My axle diameter is 9.4mm on the thread and 8.8mm on the smooth part, and respectively the cone inner diameter is 8.8mm. I have tried a 9mm cone I've got but it predictably doesn't fit.
3/8" axle standard seems close enough - but they seem to be mostly back axles which is a bit concerning. Another problem is that 3/8" cones are all supposed to go with 7x1/4" bearings, while my bearings are 4.7mm (3/16") and there were 10 of them on each side, so I am skeptical.
Would 3/8" cones and/or axle be a good fit for me? If I go with 3/8" cones, which bearings I would need to use, 3/16" or 1/4"? Would it damage the hub if the bearings are not the same size as before?
The length of my old cones (12.5mm) and their outer diameter (15mm) also don't appear to be common. I suspect it must be Shimano CN-R088, but the only UK shop where I can find it only has 1 in stock (and for £10!) If I go with shorter cones which seem to be more common (like the 9mm one on the picture linked above), would it make any critical difference?
