KMC Z51-OL Half Link, 3/32-Inch Reviews

Customer Ratings:

It was exact and cost with shipping was great. Too bad I didn't know what I was ordering. Now I have a spare part. But it was exactly as described. I thought it was half the length, not the size of the chain.

It's a half link. It does what it is intended to do. Needed to make my chain just a little longer or shorter, however you want to look at it. Works wonders for tricky single speed conversions.

I converted a mountain bike to a single speed using a White Industries ENO eccentric hub, with 45 teeth in the front and 16 in the rear I couldn't get the right chain adjustment, this half link allowed me to get the right adjustment. Using the ENO hub you want the adjustment to be in the 6 o'clock to 8:45 area, to avoid chain loosening. This did the trick
