I have no idea. The guy who started the database doesn't keep up with it any more, from what I know.

I do not have the brains, patience, organizational skills, or time to even think about attempting to think about trying that. T-Mar is a human computer.

here's a really nice '74 lemans i acquired from the original owner, now with suntour dt shifters (in place of its barcons), upgraded pedals, and non-turkey levers.

Wow that is nice. she looks to be in awesome shape especially for a 70's model. post some more detailed photos if you get a chance.

love the paint scheme on the '70s bikes. very elegant.

this one is about the smallest bike i could ever ride, given a little longer seatpost. the seat tube is a short 53cm, but the top tube is much longer 56cm. notice how short the head tube is. that's one tall stem.

surprisingly nice ride.

Super Ace bike, screams 70's. Fits me. very nice.

Which means all is right with the world.

^ yep! it's a little like walking out of the casino with even money.

.

i wanted to add one data item to the above build to aid any future internet searches...

q: whats the correct seatpost size for a 1974 centurion lemans?
a: 25.8

t-mar wrote me a couple long pm's to help me out with this build, and i want to thank him again. i did make a big error on this one though. it was the error of a real novice, and i should have known better. in short, i should have figured out the seatpost issue and its appropriate diameter before building up the bike, especially building the bottom bracket. here's the long version...

the bike came to me without a seatpost clamp and saddle. the 25.8 seatpost in the frame wasn't stuck, but it was really hard to remove. i just assumed (wrongly) that it wasn't the original post and it was the wrong size. before resolving this issue, i built up the rest of the bike, thinking i would figure out the seatpost later.

i stupidly tossed the old post and ordered a 25.6 post from asia. in the meantime, t-mar told me the 25.8 post was indeed the right size, and that i should have removed the scale inside the walls of the seat tube that had built up over the last forty years to allow it to fit properly. i was to do this without the bb in place (in case shavings fell into the shell), preferably with the frame upside down. but i had already ordered the new post and the bike was already built up.

the one-size smaller post fit well anyway. i got lucky the seat lug didn't close before the post was tight. but my inexperience and impatience cost me over $10 and the risk of damaging the frame.

it all worked out, but, live and learn. it would have been a lot easier to solve the seatpost issue with just a bare frame, not a fully built bike. maybe this bf post will help someone.

nice! most interesting to me was the "super elite" which I had not known existed (and will now keep my eye out for). 77-78 was a good 2 years for centurion.

Saturday, I stumbled on a Centurion Semi-Pro behind a shed among the leaves after following a vague Craigslist ad. I will post a separate thread about the bike, but it's a grey/silver color with the same component group listed in the 1977 Centurion catalog for the Semi Pro (Gran Compe calipers, Cyclone derailleurs, Mighty crankset, SR stem bars and seatpost. Of course, it's a chromed frame with only the lugwork and dropouts exposed. And...it's in my size, too.

Serial number = M7B01548, so 1977, late January, 1548th frame. PG

The only changes made sometime in its life were:
- mavic rims laced to Phil Wood =8^O hubs, keeping the 120-mm spaced rear
- Shimano 600 downtube friction levers instead of SunTour

If it fit, and you didn't pick it up, I was going to send you a letter bomb.

The bike was resprayed some years ago and I lost the decals. I have a very helpful local expert making a new set for me but we need a couple of things to complete the project. We need a close up and clear pic of the Equalizer logo on the top tube and measurements for all the decals before printing. Can anyone help me out please?

I'd take a bet that the logo sizes will be similar on other bikes of the same year, so if someone could be kind enough to measure another Centurion up, I'd appreciate it too.

Here's my bike so far...

Robbie, It gets worse. I didn't mention the 1989 Miyata 718a in 56 cm that I brought home with it. Snazzy. Same seller..."what about that bike over there? Is it for sale, too?"

You were looking for one of those?

I was. I test-rode a 718a, 54cm, in blue, and it killed me to say no.
What are your plans?
