It's a 415 chain- Tricycle/ Industrial from KMC corporation.
Pirates has some in silver I think- I queried there a couple weeks to make sure but didn't get an answer
He claims a quieter smoother running chain- I'm hoping for those and maybe less resistence to pedalling
At any rate- it's considerably LIGHTER in weight- I'm thinking maybe 20-25%
a substantial amount on one of the weightier items in a kit-
I tried a narrow 410 and sprocket a few years back and it derailled the first attempt- so I just went back to the kit chains
This chain makes up for that- it's just as WIDE- it's the same size otherwise- just a lot less metal on the links. It really just looks and feels a whole lot lighter- when I get the other off I'll compare the same length.
I got mine on e-bay- they have a ton of KMC 415 H chains- the H is for Heavy Duty- and while I think they are lighter and higher quality than kit chains- this Tricycle chain- listed as 415 only- no "H" behind it- is lighter still
I got basic gun metal grey for under $12 shipped. 110 links.
I was going to get a silver one from the Pirate and paint it anno- but since I never use a motor tensioner- I still have a bit of chainstay rub now and then
so I'm NOT gonna jazz it in color
The silver one's a little more at Pirates
can't wait to get it on and try it out- I'll report back here then.
here's some pictures next to a kit chain
