It’s A Shimano
"Opted for the XTR M9100 chain where I usually get the XT instead. Shifts smooth and is reliable. Remember the side marked outside, should face away from your bike."

"Opted for the XTR M9100 chain where I usually get the XT instead. Shifts smooth and is reliable. Remember the side marked outside, should face away from your bike."
"I usually use KMC chains, but splurged on the XTR chain for a new 12 speed build with a mix of SLX (crankset, chainring, cassette), XT (derailleur, shifter) and XTR (bottom bracket, chain). Quality is nice, shifting seems smooth so far."
"Exactly as described."
"I was surprised that the chain came so quickly! We got it, waxed up nicely and installed, and it is smooth as can be!"
"Replaced a XT chain. Shifts super smooth. I haven't put it on a scale but assume it is at least a few grams lighter. Hoping that the XTR 12sp chain has similar longevity and strength as previous generations. I have found that 11sp XTR chains stretch less and have longer life than XT and KMC chains."
"Great, durable chain for Shimano drivetrains. Getting well over 1k miles before hitting .5 wear on an Orbea Rise using good cleaning/lubing habits - very pleased"
"Quick delivery and great service"
"Chains are the most counterfeited bike component and this one a real one."
"Best, longest lasting Shimano chain. Period."
"I believe this chain is the best value out there. The build quality is fantastic, as is expected from Shimano, a reasonable price, and the smoothness and shift quality is superb!"
