Default Re: Chain size chart

you list that the 415 chain is only 1600 pounds tensile strength , it just depends on the manufactuer. i have a DID 415ER chain that rates 4090 pounds average tensile strength. its kinda spendy compared to other chains but i dont think breakage would ever be an issue with it.
to me its like spend alittle more, worry alittle less.

I agree, that chart is for standard duty chain. I copied and pastied it as I found it, It's just a bisic chart so people will know what standard chain will withstand.

Sooooo here I sit like a bird in the wilderness. I want to upgrade my chain to the strongest one I can get. I believe I have the 415 on my Starfire GT-2 48cc right now. Any advice??

i put into google "41# chain".
then switched from "everything" on the sidebar to "images.


then by looking @ the size chart you can figure out the sizes not shown.
ie: 410 & 415 are not in the pics. they do have the same length & pitch as 40, 41, & 420. they only vary by with.
so 41 is wider than 40,
then 410,415, and then 420.

i think i made a mistake in my sleepiness.
so from wiki i found this quite helpful
Quote:
The first digit(s) indicate the pitch of the chain in eighths of an inch, with the last digit being 0 for standard chain, 1 for lightweight chain, and 5 for bushed chain with no rollers.
so our chains start w/a "4" so that tells us that it is 4x1/8=1/2

i just found this site that has anything ever to know about any chain for gears.

Since i have upgraded everything else on my bike, i set out to find the best chain i could find. I reaserched everything. Since i wanted to buy once and never have to worry again. I found the highly rated D.I.D 415ER 4090 Pound tensile srength. Probably way overkill for our use. but it is a perfect fit for the machined gears for like the MM hub adapter. Im more into quality and peace of mind.
Its not cheap but the best price i found is here if your interested..

This may sound crazy but #40 is wider than #41, #41 is wider than 415, #415 is wider than #410. The chart shows that in the width.
