Broken chain

[zee]

Hi Guys

Went out this morning for a ride and 10kms into the ride i broke the chain.my bike is six months old with ultegra components,rode the tour durban last week and cleaned and lubed the chain last night.the chain broke outwards at the link.

i,ve ordered a new chain online which is the kmc gold chain.

is the chain a good choice and should i check the other components?

thanks

Ultegra 10 speed chains are notoriously weak, well from my experience. KMC should be better yes. The chain will skip if your cassette teeth are worn though, but I doubt it if the grouppo is only six months old.

Shimano in general is notoriously weak...

Veyron, lets not turn this into a Shimano hate thread its unnessacery, and uncalled for.

A broken chain in the fashion you describe, usually happens for one of two reasons: poor shifting, poor installation.

 

A poorly installed chain will break very soon after installation. I'll leave it to you to narrow down the reasons for the break.

 

A worn chain does not break more easily than a new one, as the wear does not affect the bit that keeps the chain linked.

 

Since a poorly installed chain is very likely to break soon into the race, it is bad strategy to install a new chain after every stage of a multi-stage race such as the Epic. I've seen people with too much money and too little common sense to this. They probably think they're eliminating break-downs when they are in fact encouraging breakdowns.

 

 Finally, a broken link is no reason to replace the chain. If it is still within spec (I've described the measurement technique here often enough), simply remove the broken link (and its neighbour), spice the chain and go ride.

Is it a hate-thread if he's stating a fact....?

Stay with Shimano as these  components are designed to work 100 % together, mixing and matching is not a solution. I agree with JB as poor shifting and or poor instalation is most probably the cause of your chain breaking.Shimano chains are designed to fail at 9000 Newton Metres of Torque. A small average size motor car only delivers 200 Newton Metres of Torque.

Are you sure you don't mean 9000 Newtons?

N.m is a pretty useless unit for measuring chain strength: you could get it by attaching a really weak 9 kgf chain to a 100m lever or by attaching an impossibly strong 90,000 kgf chain to a 1cm lever.

You could make the former out of a biscuit and the latter out of the same stuff they made Wolverine from.

 

PS. To normally break a 9000N chain you'd need to put out 3kW at 30 cadence or fit a 180mm crank, 22T chainring, and find a 230kg volunteer to stand on your pedal.

Can you say this in English please

Confucius say: To break chain requires elephant.

[The Saint]

Ahh Ok now I understand

[TheLegend]

I break chain - am I elephant?

This is how I see it, so this is how I'll call it.

 

This is Steven shamelessly plugging his own products.

 

I'm sorry, but implying that it's bad to use a different type of chain with your own products is blatantly biased.

 

We're talking bicycle chains.....not Formula 1 cars.

 

There are plenty of companies that have been producing top quality chains for many years....KMC, Sachs, Wipperman to name a few.

 

Anyone should feel free to use any of these as it's highly unlikely that any normal person would be able to tell a difference in performance or longevity of the chain.

 

I'm not bashing Shimano here. I'm a firm supporter of Sram yes, but have had better experience with and still prefer the Shimano XT chain.

 

I just think that statement needs to be called out for what it is!

Minty, agreed!!!!  Steven, I respect you for supporting your product, but don't "slate" (sorry, lack of a better word, my Eest Rant english aren't vhat goot) the other products on the market.

 

As for the problem, I think JB nailed it again!!!!!
