Hi everyone. This is an incredible resource, thanks to everyone who made it possible.

I've decided as my cold-weather quarantine project to rehab my wife's Centurion Lemans. She purchased it in college (~2009); it's been sitting unused in a shed for the past 3. The extent of my geared bike experience is on a 10-speed townie. The rest of is single speed and fixed. Great time to learn how gears work.

Serial number is N4H7115. Based on the formula here, I think this equates to 1984 production, maybe March?

Based on the 1984 Centurion catalog on Sheldon Brown it looks like most components are original, or at least same brand/style replacements. It does have a Specialized stem, which I believe to be an S-2 Road. The saddle and pedals are clearly replacements from when she bought it.

I cleaned it up today to see what I'm working with. At a minimum it'll probably need new chainrings (worn), freewheel cluster (worn), seatpost (rusted to hell), pedals (prob try to go original), and seat.

Cheers!

I was having trouble deciding if the rear dropouts were stamped or forged but now that we have a better photo, they appear to be 3D stamped dropouts. I wish you better luck with your next potential transaction.

I would suggest that the serial number reads as F2J24735, as opposed to F2024735. The first number 2, after the F, for the year of frame manufacture 1982 and the J meaning some point within that year.
The "J" probably does not mean February.

In 1981 Fairly serial numbers had a letter after the first digit, the number for the year.

In 1983 within the Fairly serial number the letter for the time period was replaced by two digits for the month within the year of frame manufacture.

The length of the 1983 serial number remained at eight characters, so the number of characters for the sequence number was reduced.

75-76 Centurion Super Le Mans

Hey gashepherd, I just picked up a very, very similar super le mans but slightly larger 23" frame. I dated my components as ranging from 1972-75. Front Cyclone derailleur date code of OF, rear Cyclone GT derailleur date code PF, Diacompe center pull brakes dated 0375, fork stamped Tange 5E and seat post marked 75.9 (took me 3 days to free it) Frame SN is TE29459. If the E represents a '5', we'd have 1975 frames. I'm guessing (pending T-Mar confirmation) I've got a late 1975-early 76 Super Le Mans. And yours will probably be very close in age based on similar SN. Main difference I see is that mine has downtube shifters vs your bar-ends. I hope this helps and adds to the T-Mar's database.
SR seat post date code?

Frame SN
