Joe24 said:Do motorbike chains break more often then because they are more wider and so going by that theory, the more leverage is there so they just snap?
Dave5N said:Joe, if you are breaking 3/32 chains, it ain't the chains, it's you.
Unless perhaps you have a better jump than Mr Cavendish.
If that's the case, I'd ring 0161 274 2000 sharpish.
Hover Fly said:A 3/32" chain is stronger than an otherwise identical 1/8" chain. To put it simply, the chain breaks because first the rivet works its way out of one side plate, then the other side plate can't take the full load and snaps. The rivet works out of the sideplate more easily on the 1/8" chain because it has more leverage.
Wippermann, the only maker I can find figures for on the web, give a minimum tensile strength of 9.1 kN for 1/8'' chain against 10kN for 3/32".
Hover Fly said:The simple answer is it doesn't. Back in the days of fixed or Sturmey-Archer and Renold chains, cyclists didn't bother carrying chain tools, because, as my father said, "The frame is more likely to break than the chain".
Joe24 said:I dont understand this.
You have said that 1/8th are more iikely to have the rivets come out, and now your saying that the chain wont snap
rustychisel said:I think you're being obtuse. The answer was given in theoretical terms: 'all other things being equal a 1/8 chain is weaker because the pin can be levered from a greater angle' or somesuch. Doesn't change the fact that the answer given is [theoretically] correct.
bonj said:All other things being equal, a 3/32 chain is stronger as it is less likely to break by being hit by lightning, as due to its narrower width the lightning is more likely to go one side of it rather than hit it. Doesn't make it any better...
