Chain snapped

[benb]

15 mins into a ride yesterday my chain snapped. I rang my wife who came to get me and I went out again on my other bike.

Very annoying though as it was on my new bike with only about 100 miles on the clock. That shouldn't happen.
I haven't looked to see if a pin pinged out or whether a link sheared.

I'm going to ring the company who I bought the bike from - they should send me a new chain free of charge, right?

You're obviously producing far too much power!

I would have thought so, at the very least! Because the thought of a chain snapping after 100 miles concerns me. I'd be asking questions of 'fit for purpose', mechanics, the store...

I know it's tempting fate but I've never had a chain snap. 5 bikes, literally tens of thousands of miles. I'm almost at a loss to know HOW it could happen.

2 chains went on my sportive yesterday in the 1st 10 miles !

A new bike should not need a new chain unless it was made of cheese and was poorly set up , i would try and get a whole new bike out of them ore a refund !

They're sending me a new chain. The bike itself, Genesis Croix de Fer, is a joy. It's not a cheap bike though, so I am disappointed. Hopefully it was a bad chain, and I won't have any further problems.

Shimano chain by any chance? A tip for any other shimano chain owners, look for the joining pin (it has a flat grey profile, looks different to all the other pins on the chain. Take it out with a chain tool and throw it away. Rejoin the chain with a SRAM powerlink. I have done this on all the Cube stable of bikes... there are just too many "my shimano chain broke"stories out there!

Not long ago fitted brand new KMC X10SL chain (expensive!) After less than 200 miles use, while on club run, intermittent clicking heard from rear end - thought rear mech needed adjusting, cassette changing, maybe? - BUT - before next ride, was lubing chain and noticed one of the side plates had come away completely from a roller at one end, angled outwards (not the quicklink). Lucky I noticed it. So even the top end chains can be faulty.
(I would have taken it up with the supplier but had bought it on offer 2 years previously, so doubted i'd get any comeback.)

The Shimano HG-53 is generally a reliable and long-lasting chain. Got to have been fitted shoddily/wrongly.

When you get the chain make sure it's fitted the right way round.

I had a look at the chain, and one of the links had actually broken. The thin part that looks a bit like a lollipop that the pin goes through only had one side. I don't know whether it bent and then the action of cycling made it break, or whether it just went.

These things happen.

Have a quick look at this thread. It seems new bikes may be fitted with el-cheapo chains just to get them out of the factory on budget.

I know of several recumbent owners who have snapped a 9 speed KMC chain. I use SRAM PC951 , have done for years and like both the link system, I do use a specialist tool for breaking the link, and the life I get from them, but most of all I like the price.
