Just put this new chain on. It uses a quick link instead of the old pin technology. That seemed to simplify installation for me.
I'll definitely pick this chain for my the replacement on another bike.
Have never had any issues with Shimano chains, and this one is no exception. Got this for my friend's bike that I tuned up for him. Really like that it comes with a quick link, as I always order a KMC link to go with the 10-spd ultegra chain for my bike if it happens to be on sale. Not sure if it's just in my head, but I feel like Shimano chains run just a little quieter than KMC, but shifting performance and longevity are very similar, so I tend to go with KMC more often simply due to price, but I like grabbing Shimano occasionally when they have a good deal going.
It's a chain. It does chain stuff - it is reliable, sturdy and durable. These come with a master link aka quick link aka missing link. I use these chains on my Ultegra Di2 11-speed setups. Keep the chains clean and serviced, and they'll last quite a while. I can run about 4,000 miles on one until I am due for a replacement, and I remove them and clean them in an ultrasonic parts cleaner about every 1,500 miles. I clean and re-lubricate them about every 150 miles, or when I get them visibly dirty - whichever comes first.
Smooth shifting, long lasting chain at a good price. I prefer not to mix brands on my drive train - Shimano cassette, crank and chain on my Di2 road bike. Likewise, I use only Sram chain, crank and cassette on my mountain bike. Compatibility insures everything works as it was engineered
The quickest and easiest way to renew your drivetrain is by replacing the chain. If you use Shimano Ultegra 11 this is the only chain to buy. Its an exact match with the Shimano 11 drivetrain cassette and chainrings. Replacing the chain more often will reduce wear on the expensive cogs.
Can't comment much about chain per se. Can only comment based upon experience with present gear setup. Have 34-50 compact gear rings with 11-32 cassette. Seems chain is not very tolerant with this setup. Had to replace chain despite Park Tool measuring tool did not even indicate 0.5mm of stretch, or wear. Not chain's fault.
The chain was very noisy. At first I thought it was front derailleur rub but not the case. The chain would also occasionally sound as if it was jumping a cog. It was a bit quieter with a ton of lube but still not acceptable. The chain direction was correct and even after 700 miles it never stopped. I think I'm going to try a Sram 1170.
I have this chain on several bikes and it works great. It also lasts quite a while although I don't tract mileage on my chains. I do take care of them however. Lube when necessary. On the rain bike, WD-40 to displace the water and chain lube for it's intended purpose.
