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

Works on 8 speed cassette nice quality included quick release link for maintenance. Old chain was badly worn so well overdue

despues de unos 600km se rompio una ves, la repare y a los 3 dias se rompio otra ves, ya la tire a la basura

Top quality and easy to install. Drivetrain on our tandem, was super quiet and shifted like a dream .

Worn chain so replaced this time Shimano instead of the usual KMC, have to say prefer the quick link of the KMC the Shimano one feels weak! Meshes fine no adjustment nice and quiet and smooth, remove the grease first then apply lube of your choice.

Good chain and runs quiet. However at 116 links it was too short. I needed to scramble and find another chain for my ebike just for 6" or so.
