when I worked out the bugs for a TA 5 triple on my '76 Raleigh, 126mm SKF was recommended by Boulder, JIS taper. I instead went with the 121 and a 4mm spacer it came out with perfect asymmetry and perfect chainline. I'm glad, because otherwise the left pedal would have been in the next county.
But Peter's analysis of ISO taper is sensible, and if it's asking for 118mm in an asymmetric spindle, you'll certainly need that much on a symmetric BB. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
