Reply To: New member, swinging arm upgrade.

Hi Blenky

I am not 100% sure that the B3/B4 needle rollers will fit straight into the B1/B2 swinging arm. However I do have a B1/B2 swinging arm with needle rollers fitted so yes it can be done. You will need the B3/B4 sleeve which I don’t have.

Cheers
