Like I said, I've never boken a chain. Short bursts? How about long bursts up mtb trails?

So you're saying shorts burst on an mtb are more punishing on a chain than climbing 62 miles up into the mtns, some grades of 22%. Done on a 39/25 standard double when your mtb is geared with a superlow gear of, maybe a 22/27?

This is where I ride offroad. A 5 mile loop, the first 2.5 miles very steep. I must say I've never seen an uberclyde climb this hill. I do 3 loops when most do 1. Believe me, mtbing up these hills with a low gear isn't any tougher than climbing 10-22% grades on a standard roadie.
