I’ve long used KMC chains, managed to get a great price on a couple of KMC 10 SL, the very high end 10sp ones they do. The first one ended up snapping 4 times, I’m a frequent user of a chain checker so I didnt leave it on the bike for a very long time. The new one has been on a couple of weeks, I had a spill last weekend on a night ride, dropped the chain, got it back on but it was clicking away, before long, snap.

How do you guys get on with them in terms of wear and tear? They dont weigh much but I’m starting to think its a false economy.

No. Did break a couple of X9SLs, but then I’ve broken every chain I’ve tried! Latterly a Dura Ace one on the road bike.

Never broken an X10SL though.

its always a pay off between weight and usability IME

My SL has been fine at 9 speed though-£40 ish from Merlin

A poorly made batch hence much cheapness??

Came from two different sources, Merlin and a guy in the Far East I’ve regularly bought kit from. Maybe will give it another shot but it broke on a race last week and spoiled my night, maybe not the part of the bike you want to try and save too much weight.

Oh and I got the gold one for extra tartage points so I probably deserve the bad luck.

The Sram 991 chain on my P7 has 9 powerlinks in it , I have far less hassle with the 950’s on my other bikes.

Buy from Taiwan via eBay – <£25.

Cyclistbike on eBay is the shop I’ve used, very good, in Taiwan.

I would rather support my LBS.

It really is FWIW

I use KMC SLs of one form or another for years on most of my bikes and never had a problem *touches wood*

I had some trouble with my X9SLs… Never broke one while just riding, but I often bent them through chainsuck- the sideplates were easy to twist. One soggy lap at 10UTB left one pointing every direction but straight and gave me a lot of trouble. Easy to straighten out again, mind!

So I stopped using them but they were definately fit for purpose, they just struggled more at the limits.

Always buy the best KMC from eBay Taiwan, never ever a problem.
