No, I just like their products for value. Particularly the Mavic branded 10S8s I bought for £10 each :-)

Also, the 1Z1 and 1R8 are the only bushed chains easily available without paying hipster tax on an NJS chain.

Should also mention that the quick link that comes with the 7Z1 is not designed to be used to rejoin the chain multiple times. Tbh I wouldn't even use it once. Don't know about the others.

Good point well made, I'd forgotten that the 7-speed comes with a snap link, I only have one, whereas I have numerous 1Z1 ⅛" versions which come with a spring clip master link. The 7R8 comes with a spring clip, as does the KMC S10 on sale at On-One
