Do I really need to carry a chain link tool ?

[Rooster1]

I've been carrying a chain link tool and spares for the past ten years and I've never once needed it. I inspect my bike regularly and I swap the chain when it is worn. I do recall once having half a link come apart but I managed to make it back to base. The tool is heavy and clunky.

So should I continue to carry this thing that seems redundant?

I broke a chain in the midst of Scotland on a Sunday !

Carry it

You'll be fine if you buy decent chains, change them when they should be and most importantly fit them correctly.

I've never heard of a snapped chain that isn't due to one of the above.

 

[I like Skol]

Carry it! Stuff happens and it is one of the few tools that you will not be able to borrow from a non-cyclist if the worst should happen.

I have used mine 'in the field' a number of times, although rarely for my own bike, but it can/does happen and the repair is preferable to the alternative.

WRONG!

Have always carried one, only had to use it once in the last 5 years, but it saved the guy getting a cab home.

In the past 5 years cycling I've had two broken chains, both of which I've sorted using the chain breaker (that's what you're referring to, right?) and a spare quick link
Only last week I offered to help a cyclist with a snapped chain who was walking but he was almost home
I'd regard it as a good decision to take one with me, particularly as like @I like Skol says, you can't fix it without this specific tool

Carried one for 5 years, needed it once a few weeks ago, top tip if you carry one, make sure it actually works

First, no need to shout...
Second, I think most people don't realize it's a user error but how many pro cyclists brake chains when pushing 500w? Now consider we put out 1/3rd of that. I'm not saying it never happens, just extremely rare.

 

[Racing roadkill]

Yes.

Split a length of worn out old chain, and see if you can get the outer plate section off the split end using something that you will have on the bike - eg lever off with a screwdriver end.
If you can get it off, it's OK to carry just a spare quicklink.
Otherwise you'll need a chain tool to get mobile again. It's up to you whether the cost/inconvenience/brownie points needed to get home without makes the chain tool worth carrying or not.

Broken chains aren't common (IIRC, I've had 3 in 150,000 miles), but aren't always due to bad maintenance - I have seen reports of bad batches of chains, of most brands, where a new or hardly used chain has cracks between the pin and the edge of the outer plate in a number of links (as found after the first broke).

 

[Pat "5mph"]

Yes, just in case, could help others as well.

I snapped a chain on my way home from work starting off from a set of traffic lights. Chain was fairly new, regularly cleaned and lubed and generally looked after. The chain tool allowed me to just shorten the chain and after a few minuits I was on my way home via the LBS to buy a new one. So the answer is yes.

I've only need one before I started carrying it. My the bolt holding my derailleur hanger in place fell out, so my bike was only wheelable. I was a very long way from home and about 200km into a 600km audax. The nearest bike shop was only a couple of miles away, but closing in 20 minutes. A chain breaker would have allowed me to convert to a single speed and make it there.

Luckily a stranger borrowed his neighbours car (?!) and rescued me, but that's not a common experience.

The tools aren't necessarily that big, and are often incorporated in cycling multitools

Actually, I have seen quite a few over the years! Presumably pro teams don't use cheap chains and pro mechanics know how to fit and maintain them ...?

I was once riding some Scottish MTB trails with a friend. She only weighs about 7 stone and we were on a flat gravel track in a forest, so she wasn't exactly hammering the chain. CRACK - it snapped! She had only had the bike for a couple of weeks and it had been assembled by an experienced LBS mechanic.

I fixed it for her in a few minutes using my trusty chain tool. I have also repaired chains for 4 or 5 other riders over the years. I finally broke one of my own chains on a ride a couple of years ago. Here's a picture of the broken link ...

It snapped for no apparent reason. Just one of those things. The chain was otherwise in good condition and I wasn't doing some crazy gear change on a steep hill at the time.

With the tool, no problem - 15 minutes later I was riding again, after also taking some photos and having a snack and a drink. Without the tool, a BIG PROBLEM!

I'll continue to carry the chain tool!
