Howdy all,
I am new to this site but I just picked up a very cool Workman(will post picks later) and I have a couple of questions.
1)Is the headset a normal 1 inch? If so, will is accept any 1" headset?
If not, what kind is the best to get?
2)What is the seat post diameter?
Thanks.
BTW, some really nice Workmans
Answers:
1- No, the headset is NOT a "normal" 1". It's one of several, older-style US "standards." Basically, the headtube is much wider diameter than the smaller ones. Even most "BMX"-sized 1" headsets (which are 32.5mm OD at the skirts) will be a loose fit in a Worksman. (I put a BMX-sized Chris King in on one of my Worksmen, but I had to shim it.) Best bet is to use an OEM Worksman headset, but the Wald #4080 will fit, too. Seems like really old schwinns took the same size, but later schwinns seem to be 32.5mm.
-1a- I havent tried it yet, but Genuine Bicycle Products sells a 1 1/8" threadless headset designed to work with these headtubes. If you went that route, you could run a modern 1 1/8" threadless fork and stem on your worksman. Speaking of stems, if you are using the original fork, you'll need a 21.1mm (aka, 13/16") quill stem. This basically means old-skool or old-skool-style BMX threaded stems, Wald stems, or vintage stems. The modern 22.2mm quills found on most contemporary 1" threaded bikes (and many bikes from the 70s) will not fit without modification.
2- The seatpost diameter is, as Heyslugger mentioned, 22.2mm. This equates to a true 7/8" post, and you may well find compatible posts identified as either/or.
I love my worksman, but I have to admit that they are quirky machines. Things can get weird if you've never built an old-timey american bike before. Really, though, you just gotta be ready for the headset/stem issues, and be aware that using non-stock headsets and/or forks could lead to issues with stack-height and the amount of available threads on the danged fork.
Please put up some pics of your build!
(can't recall if i already posted this, and I'm too lazy to go back n check...)
hth,
