I had been meaning to check chain (SRAM PC-X1) wear on the T275 and got around to it yesterday. Put the gauge on, found that it was worn out. I haven't been keeping track of miles ridden this year, but didn't really expect to find that much wear.
Not sure but I was reading Park Tools recommendations the other day and they say 11sp change chain at 0.5 vs 0.75 on 10sp. So that alone would make the chain wear out quicker.
Still running 9 speed myself, but have found that I can dramatically extend the life of a Sram chain by removing it to lube. I unhook the quick link, lay the chain on a bench, apply lube, and let it soak in before wiping and reinstalling. The inside of the rollers stay lubed and there is not any excess on the outer surfaces to hold dirt and grit. Been doing this for a few years now.
I don't really know, but I replace my 11-spd chains more frequently in an effort to get more life out of the super-expensive 11-spd cassettes. Cool to see some 11-spd alternatives hitting the market (like e.13).
No they don't. Chain size has not changed. They are still 3/32 X 1/2. The outer plates are thinner and the rivets are flush. The pins are fixed to the outer plates. The inner plates are thinner too but The bits that wear, inner part of the pin, rollers and the inner plate bits are the same as ever really.
Not only that, but with more cogs on the cassette, in theory the wear to them is spread to more usable gears so cassettes last longer which means chains do too.
