I’d say its more likely to be setup or technique rather than the chain itself.
Were you changing gear at the time?
Did you stamp on the pedal?
Was there a stiff link in the chain ie where it was joined?
Is the cassette or chainset worn?
Are you using the correct joining pins if its a Shimano chain etcPosted 5 years agothisisnotaspoonMember
IME all my snapped chains were down to technique and forceing the gears to change too quickly, never snapped a chain with rapid rise mechs, lots of foreward planning and shifting before the gears needed not when it’s needed and I’ve not snapped one in years.
It’s not nececeraly shifting that snaps the chain, it just forces it to work at a sharp angle between the mech and cassett that forces the outer plate works off the rivet, so the next time you apply some power it pulls the link appart. So the dodgy shift could have occoured minutes/hours/days ago.Posted 5 years ago
I snapped another chain yesterday and bashed my knee on the stem. To be fair it wasn’t new, but it broke quite spectacularly. Do chains get stronger the more you spend? I’m looking at one of these spangly ones
Any good?Posted 5 years agojamesoSubscriber
The only test info I saw said the chains with shorter pins tended to have the highest strength. And that strength was a UTS of such a high number that there’s almost no way you’d break a chain with pure pedal force, it’d need to have been fitted wrongly or be damaged somehow first. Or, you’re Chris Hoy.Posted 5 years ago
