Sugino 75 with UN52BB?
I have a new set of Sugino 75 track cranks and need a bb -- I finally
killed the 1975 campy cups and spindle. Can I use a shimano UN52 with the cranks, or is there a different spindle shape? TIA Scott |

The 75 crankset is new, so I can't really compare. My old crankset was
some no-name stuff I pulled off a spin bike, and the old bb is shot.

If in doubt, measure the old taper (across the flats as close to the free end as possible) and compare to a Shimano one in the shop. The JIS and ISO standards only vary by the initial size of the taper, as the angle is the same. |

TIA If i remember correctly (www.businesscycles.com) the Sugino 75 track cranks want a 103 mm symmetric spindle. Does the UN52 come in 103 mm sizes? - Don Gillies San Diego, CA |

oups.com... I have a new set of Sugino 75 track cranks and need a bb -- I finally killed the 1975 campy cups and spindle. Can I use a shimano UN52 with the cranks, or is there a different spindle shape? TIA Scott Scott: Sugino 75 cranks takes a smaller cross-section square-taper spindle. I have tried this crank with a Shimano (JIS) taper BB. The result is that the chainline moves out (wider) about 3-4mm on each side, and the engagement between the arm and the spindle is correspondingly less. I suggest finding another Sugino 75 spindle, or a Campy (ISO) spindle, which would be a much closer fit. An Ofmega/Avocet spindle of the right width (and left-right symmetry) would likely also work. Old Dura-Ace track is another option. BTW: you may be able to use generic BB cups designed for 1/4" balls. Cups generally come in the thick or thin variety, so you may not need to hunt around for special cups. |

It definitely did not work with a Shimano taper BB. Sugino must have gone to the JIS taper since that time. You say the Sugino crank you have is new. Was your crankset freshly manufactured, or perhaps sitting in a box for a few years? I suggest testing the engagement of the crankarms on a Shimano BB before you install everything. |

WHen you say "didn't work" does that mean your spindle length was incorrect or that the taper did not engage properly? When you say 'Shimano taper BB" do you mean a current model and if so which one?

Shimano has only used their current taper section from the early '90s on Sugino 75 here go with a Tange 110mm BB My experience with the Sugino 75 crank basically mirrors Dave's. This is a brand new crank, taken off an 04 fuji track bike. It came with a fairly generic 110 bb and the chainline was a few mm wider than 42mm. I then put it on with a shimano UN-52 with a 107mm axle and it was still a little wide. This really surprised me as I had a hard time imagining that sugino doesn't use a JIS taper. I've been meaning to play around with some campy BBs and probably to get a sugino 75BB if Quality ever has them back in stock, but just haven't had the time. Baird |
