I am trying to find a suitable replacement for the headset (1" threaded) on my bike. The bike is a
2000 Dawes Sonoran - a hybrid bike, aluminium framed, mainly used on roads, but also on bridleways
and gravel tracks.
The current headset would appear to be a "no-name" affair (at least no manufacturer was willing to
put their name anywhere on it!).
From measurement the stack height is about 39mm-40mm, including 2mm of washers (2x1mm) (presumably
this makes the headset itself have a stack height of 37mm?). Alternative measurements are a fork
steering column height of 182mm from the top of the shoulder "lump" below the fork race to the top,
and 142mm for the head tube (outside to outside).
I have been looking at the possibilities, and found several likely candidates:
Shimano 105 (HP-5501) Stronglight A9 threaded 1" Stronglight X13 (apparently discontinued)
Stronglight inform me that the A9 has a 38mm height, and Shimano quotes 37.5mm.
Somebody suggested that the Campagnolo Chorus 9 might be also suitable, but probably too large (at
40mm stack height) - or at least very borderline.
I don't really want to spend more than 25 pounds for the headset itself, ideally less (plus fitting
costs, of course). OTOH, I am so fed up with the constant fiddling needed by my current one that I
don't mind paying for better quality if it means that it won't keep coming loose and will last
longer than the current one.
Does anyone have any suggestions/experience of any of these or even a more suitable one to use?
Thanks.
