Available diameters on integrated headsets?
hi guys, The short question is:how many different diameters can I find integrated headsets in? The long story behind is as follows:when I built a bike around an unknown frame some years ago I wasn't aware that there was such a thing as an integrated headset, so when the stock 1 1/8 didn't fit in the head tube I cut a couple of spacers/bushings on the lathe and stuck it all together. Now, somewhat better informed, (and in need of a 1 1/8 for another bike) I'm thinking of replacing the 1 1/8 with an integrated set, but I can't remember the i.d. of the head tube. Can I buy 'this one' (http://tinyurl.com/22rnk4) for instance, and expect it to fit? Or do I have to do an explanatory disassembly to find out the i.d. of the head tube before I buy an integrated headset? -- dabac |

If your local shop has the excellent FSA Stainless Headset Guide, consult them. It's a well designed tool and quick to use. The various formats and nomenclatures certainly are confusing! -- Andrew Muzi www.yellowjersey.org Open every day since 1 April, 1971 |

I meant that cane creek and hiddenset are the 2 main ones. Columbus is uncommon, and is actually not really an integrated system, I kinda just stuck it in there. I also forgot about the TH industries 36x36 integrated standard. =P Nate Knutson Wrote: ..... then there are some oddballs.

dabac Wrote: Ah well, exploratory disassembly it is then. Bit the bullet yesterday and removed the headset. The caliper says 37.3 mm head tube i.d. Closest match in the Sutherland's handbook seems to be the 37.5 1" JIS / Pro threadless low-profile. Could be right, the origins of this frame is shrouded in mystery. Dang. OK, so I've got a 37.5 i.d. head tube and a 1 1/8" fork - can I find a HS that would either let me get rid of the bushings and/or let me reduce the stack height? -- dabac |
