1" headset doesn't fit 1" fork or steerer tube
Did an inch used to be smaller? I have an original Cambrige Massachusetts built Merlin Mountain frame (circa 90's) with the 1" head tube. I can't seem to get ANY headset race to fit in the steerer tube. The races are just 32/nd of an inch too big. I have tried both a new threadless Ritchey, and an old Campy (threaded) headset as well as some other brand, all are one inch and all are a 32nd of an inch too big.
I have built up at least 10 bikes-- old new, both threaded headsets and thread less: Campy, Stronglight, Ritchey, Aheadset, Shimano, Mt bikes and road bikes,but this is just plain weird to me.... Any help would be appreciated. Also the fork race does not fit, by about the same 32nd of an inch.. too small to fit the fork, but that doesn't worry me as much as getting something to fit in the steerer tube. By the way I would like to set this up threadless but will go with anything that fits. thanks. |
Headset races come in 26.4mm and 27.0mm size. Make sure you get the right size. Also the frame cups are 30.0mm or 30.2mm... Measure EVERYTHING! :)

thanks for the speedy reply! Sorry about the duplicate post, greasy fingers and all..
Your response makes total sense But why do they sell 1" headsets and not 30.0 and 30.2 mm or 26.4 and 27.0? Or do they? Is this a plot to get us to buy more stuff? |

Don't try to force the 26.4 onto a 27.0 :eek: The races are rather brittle and will crack, especially if you give the race setter a mighty whack with a hammer. Don't ask me how I know this :o |

If you don't have one of these: http://www.parktool.com/images_inc/r...elp/fork19.jpg You really don't want to be working on headsets yourself. |
