Shimano Bicycle Chain Cn-Hg71 6/7/8 Speed 116 Links W/Sm-Ug51 Quick Link Bicycle Chains

I love Shimano products, and I love this chain. They resist stretching (ebike), they don't rust up. They just work. The only con is the stupid quick link. I never use theirs. I usually use a HJC quick link. It fits fine. The Shimano ones are just too hard to put on there. Otherwise it would be a 5.

My wife's bycicle, 18 speed (6 gears on rear , 3 on front) had previously been had been having noisy/chicking shifts on the rear and less than a year prior replaced the chain with a cheap ($12) one, that cleared the problem for about 8 months. The problem came back, I thought maybe the gears are worn, the bicycle is 25 yrs old, but as soon as I replaced the chain with this one, the gear shifting became smooth again. Will report how long this one lasts. 12/21/2023 Still running smoothly .

Pretty easy to replace, though I had a little bit of problems with the quick snap. Bottom line - it made my 29 year old Mountain bike converted e-bike much more responsive from a pedaling perspective. I know i said e-bike but it did help the performance. You likely will need a chain tool to remove your old chain and cut the new one to the right size, but if you're doing this repair you probably know that already.

This definitely is a high-quality chain, which is to be expected from Shimano. I used it on a 2014 Trek Verve 2 (6 speed). My ONLY issue with this item (and hence the reason for 4/5 stars) is that the stupid master link snap clip is rediculously difficult to get on properly. I do not understand why it must require so much force to slide into place. It almost had me thinking the chain wasn't going to connect together no matter what I tried. After 20 minutes, some swearing, and a lot of hand tools, I was finally able to get the silly little clip in place. At the end of it I couldn't help but feel like there was an equally secure but infinitely less difficult way to keep the master link from falling out. Only reason I went with the Shimano was for the sake of quality and since that's what came on the bike.

perfect!

I replaced my sis gears with the average gears and chain with a KMC 6/7/8 master link and the shifting is now phenomenal as is the master link close fit for waxing.

Great replacement chaing.

Works for 8 speed runs smoothly
