6 Pairs 12 Speed Bike Chain Quick Links, Reusable Bicycle Chain Connectors for Most 12 Speed Chains, Easy Installation, Silver

This is a must in any bike bag, if you break a chain on the trails this is your salvation, decided to have this in my bag after a bad day on the trails. Simple to install, good value for the money and will fit any 12 speed chain.

It’s a good idea to have several quick links available for those times when removing them has them flying across the room and you can’t find them. This brand fits well and installs easily on my Shimano 12 speed chain. The quality is the same as the original quick link.

Worked great. Look to be well made time will tell.

Made a mistake. At first I sent a review that these links are are not 12 speed. I was wrong . doing maintenance on several bikes I got the chains mixed up. Rest assured these are 12 speed links. Sorry for the mistake.

Well packaged in an easy to use blister pack

I haven't used these yet but it seems like they're going to be a great addition to the stable. I measured them against the SRAM and Shimano links I have here for a 12-speed and it does appear that they will work quite well.

Just get 'em. You need a spare or two anyway.

They will connect two ends of most 12 speed chain because the inner width of 9 thru 12 speed chains is all the same (11/128") and the plates are thin. However, the outer width of a 12 speed chain needs to be less than about 5.3 mm to shift properly. These Missing Links are about 5.7 mm (11 speed) - nearly 0.5 mm too wide for 12 speed! You may get away with them on some 12 speed drivetrains, but likely with noise and chain jumping around. when the outer plates catch the next cog on your cassette. They should work for most 10 and 11 speed drivetrains IF you can get them closed. The ones I received were so tight that they could not be closed even with chain pliers. The inner width of these links is too narrow to fit all the 10 and 11 speed chains I have (KMC and SRAM). So, for me, they were 100% useless.
