What are my options for extending a chain by a link or 2? I kind of forgot the fact that I'm currently residing in a more hilly area than home and I broke my chain for smaller cogs. And I would rather keep using this nicer chain. A smaller chaining would not be a good option.

You're using a K710 right? I have some spare links around here somewhere if you need 'em.

I'm using a mushroomed chain this time, it's the one notch higher on the KMC hierarchy, the Ti nitride coated k710sl.

"Mushroomed"?

You could just go to your LBS at ask for an extra link or two?

edit: nevermind I'm being glib.

Yes, as in mushroomed pins (look it up).

The standard 710 is mushroomed as well...just heavy as an aircraft carrier.

Do you think a half link would do the trick? As I'm currently running a 17T cog and I want to swap it out for a 18T cog which I'll have to order; and there's only very little space left before the axle touches the inner end of the track end; it seems like a tight squeeze to me; but do you think it'll fit without any chain modification? (I'm just asking for when wore comes to wore lol)

KMC makes a half-link specifically for use with 710 chains. Don't try using a regular half-link.

But do you think I'll even need a half link in the first place? I'm just asking for when worse comes to worse....

I'll have to measure how much space I have left in the track end with the 17T in. But once again it seems like a 18T should fit, but I have a nagging feeling that it won't....

How much room do you have in your dropouts? When I switched from a 17 to an 18, I added a halflink and it put my axle only a hair or two further back from where it was.

So are you saying I might not even need it?
As if worse did come to worse, I was planning to just get the izumi half link, as it is easier to acquire.

If you have a few mm to slide your axle forward, you most likely won't need it. I have an extra 710 half link if you do.

Great, I'll measure how much space I have left once I get back from work.

Just fyi, the phrase is "when worse comes to worst." Not trying to be a dick.

LOLZ I just realized this! =P Well, stuff happens like this when you're deprived of sleep and under a massive workload with a deadline approaching soon.....

The saying that a chain is only as strong as it's weakest link is very true. Why would you put a low quality half link on a high quality chain?

Hence why I mentioned, when worst came to worst.

doesnt popping mushroomed pins in and out weaken the pin? At least its not good for it, thats why chainbrakers dont like pushing them through. I would track down the proper quick link for it.

From my understanding you can't safely use the chain after replacing a once taken out link from a mushroomed rivet chain.

New chain...problem solved!

I could but I'm looking more at a quick fix; my LBS down here does not cater toward FG/SS; so I'll have to wait either way if I order online or from them.

that was mine too, i mean ive done it but not something i planned on riding very long...

I've done it without incident.
