Centurion LeMans headset
Hello,
I have what I think is a 1986 Centurion LeMans RS, serial number N6N8748, that I've converted into a three-speed commuting bike. I need to replace the headset -- anyone know what are the specs? Thanks much.
Josh

1" threaded since both the frame and headset are japanese there should be no other issues. I could be wrong but I think Robbie is the resident Centurion expert

Regardless of what a bike originally came with, I have found a couple of oddballs out there. There is no substitute for proper measurement with a digital caliper.
I had a late 1980s bike with a 26.2 crown once. That was a PITA.
Tange Passage comes in both 27.0 and 26.4 sizes.

wrk101 thanks for the response. the bike is all in 1 piece now, guess i could spend a while taking the thing apart and measuring with calipers but thought i'd try here first

Most likely a 26.4. Fortunately for me, I keep a handful of headsets in hand of various sizes. Remember stack height too, that can change everything. The bike I had above with the 26.2 crown race also had a very short stack height.

26.4 was the most common, I believe, but truthfully, I've never looked at mine.
With a 1" threaded steerer, I'm thinking 26.4. I'm fairly sure I bought a 26.4 Tange Passage for mine.
