I just set up a KMC 1/2 link on my fixie and for some strange reason the pin (that was included w/the link) is longer than all of the rest of 'em in my chain. Both the chain and the half-link are "1/8" so I dunno what's up. Its also making the chain emit a weird noise. v.strange
Are the outer plates of the half link too tight on the inner plates of the regular link?

I had this happen on a ss setup. It was also 1/8". I was using a chain tensioner that had a bar (cage) around the pulley. When I added a half link the pin would rub on the cage part. I had to scrap the project.
For some reason they make the pin longer on half links.
I can't imagine where it would rub on a fixed gear setup. I am also thinking you have a tight link.
Where is the pin rubbing on the drive train?

Well after a day of riding the strange noise seems to be from the pedals creaking, not the new half-link, so that's good - I loosened it up a bit and that seems to have solved the problem. That extra long pin is still kinda odd lookin' and I'm wondering if I shouldn't just replace it with a regular pin once I put on a new chain.
I'm taking it you don't have the half link that has a drift pin thru it with a cotter pin in the end, yeah, yeah I'll take a photo...

Wow, put on a fully nickel plated chain today, inserted the half-link, and boy what a difference a little nickel makes :) No noise, clean, smooth, looks great, sans rust-affinity. OMFG, I can't believe I had to learn that lesson the hard way. I'm still curious as to what kind of link you're referring to...

A couple of pics of a cotterpin half link

Yep, certainly don't have that kind. Looks kinda cool though. What is the purpose of the cotter pin?

i only assume to make it easier to get on and off, i have one on my flatland bike(bmx)

I thought BMX drops (or "track ends") were plenty long so that you have lotsa room for adjusting.

they are, but i like to keep my rear wheel as far in as possible(shorter wheelbase)
