Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Sugino 75/BB Question

Alright so a couple weeks ago I bought a pair of Sugino 75's and the (semi) matching Sugino 68 Mighty BB from a guy for a ridiculously good price that I just couldn't pass up. I finally got around to opening it all up and really looking at it now that the crap weather is pretty much done here and I had a small installation question that I'll try to explain as best I can. The cranks didn't have the bolt that usually comes with a crankset, but the BB(it was new in the box) came with two bolts that thread in...but they're not the normal sort, it looks like you would just tighten them down with a ratchet. That just makes me nervous, it doesn't possibly seem like that could tighten everything down the way that its supposed to, but I could obviously be wrong...its just different than what I was expecting. I tried to search for the answer but nothings coming up. Does anyone even know what I'm talking about? Thanks a bunch...

-Alex

The ratchet style bolts came with older BBs before they switched the standard to an 8mm allen bolt. should be fine so long as the spindle matches up (sugino has been known for using both ISO and JIS tapers, so a sugino BB might not necessarily match Sugino cranks).

The system you are describing was common until the new 8mm allen bolts were introduced. Just tighten it down as much as you can.

Do yourself a favour and pickup 8mm allen bolts anyways. It is much easier to stick a hex wrench in there to remove than a socket bit.
