Good Affordable QR Chain Links

I've used these links on my 10speed bike for the past two years now and have notice no loss in accuracy of my shimano 105 set up. These links are actually manufactured by KMC so you can be assured of their quality and pedigree ☺

Excellent bit of kit.

Bought these as a spare to put in my bag 'just incase'. I recently changed my chain and tried to use another well known brand to join the chain I could not close it properly then could not open it to start again and had to use a chain splitter to remove a link. Pulled one of these out my bag and used them successfully. Works well no problems since after approximately 400 miles of cycling.

Btwin 10 speed chain link

Used with Shimano Tiagra chain without issue

10 spd quick link

Fitted to a Shimano SLX 10 spd chain. I have used the 9spd links on 9 speed chains and been able to open and close the links without tools; this was VERY tight and I had to use the special pliers to close the link. I carried a 9 spd link in my bike seat pack as an emergency fix, not sure it's worth it with this unless I find a way to fit without the pliers. A lot more confidence in this than the Shimano pin though. Branded as BTWIN but actually made by KMC a well known chain manufacturer.

Doesn't seem to work with Shimano 10sp MTB chains

I've tried this with two different Shimano HG95 10 speed chains and in both cases I've been unable to fit the link, it's as if the link is slightly too narrow for the chain. In both cases, I've had to refit a different quick link from another manufacturer.

Dear Sir,

I'm sorry to read that the master link is not compatible with your shimano chain.  The link is only compatible with SRAM chains.

Please accept my apologies for the confusion.  Please feel free to return it to store for a refund.  If you no longer have your receipt, it's not an issue.

I have changed the wording on the product name online to make it clearer and to avoid future confusion.

Velmi dobré

Spojka funguje jak na řetězy Shimano, tak SRAM. Dobré balení, lze obstrihnout a spojka zůstává chranená pro převoz v např. v podsedlové brašně.

Macht genau das, was es soll und ist kinderleicht zu montieren. Zwei Stück für den Preis sind eine klare Kaufempfehlung.


Gutes Produkt

10-Fach Kettenschloss

Das Kettenschloss ist nur für laufrichtungsgebundene 10-Fach Ketten geeignet. Es kann ohne Werkzeug montiert werden, allerdings ist es mit der jeweiligen Kettenzange zum öffnen oder schließen sehr viel einfacher handzuhaben. Das Schloss ist von der Marke KMC und ist im Prinzip auch wieder verwendbar. Damit kann man z.B. auch eine Shimano 10-Gang Kette schließen.
