I DO !!!

There the don...

I Had a big argument with loads of people ages ago over Half link chains.

I Love the, i think there great becouse you can get perfect tension with Vert drop outs.

The look Awesome.

And they just make the pedals feel more.....Well, purposefull ?

Everyone else is going to call me a twat and a liar now though.

TO be perfertly honest with you there not that much stronger than a normal chain, but they do last a little bit longer.

They can be a b*****d to fit, Especially the Shadow V2.

But get one (Y)

If you don't like it youll know never to buy one again.

I think there great and use one at the moment.

But, everyone else said that they weigh a ton, and they dont get loose then snap, they just snap.

But as long as you check the tension of it before a propper ride it'll be fine.

And here is the Other end of the PAge.

Avoid them, they are a Bad Idea.

I was Speaking to the Guys on Team Extreem Last year when we did a Show with them, and The topic Came up.

Chris Mahoney Was telling me how alot of BMXers he rides with have all gone off the 1/2 link because of its bad design.

And funnily enough That same day Craig Lamptons 1/2 link chain snapped, and did that same thing the very next show.

The chain has a structural weak point on the bend

Where it goes from an Outside link to an inside link in a short space.

My advice would be to buy a decent "noraml" chain. Ive been running the Sram PC48 chain for over 8 years (changed when worn) and had no problems at all.

My guess is the half link chains will feel springier under load as the tension in the chain will try to straighten the bends in the chain plates rather than having to actually stretch the side plates as with standard chains. That bending stress will probably lead to quicker fatigue cracking than a standard chain as well as slightly poorer power transfer. KMC cool chain is probably a better choice unless you're really desperate to run your bike without a tensioner...

Don't go there. Just go the safe option and get a KHE Collapse of Tarty. Might be heavier than some but atleast you will feel safe.....

A good chain shouldn't get loose OR snap.

I went and bought one. It was all the local shop had in anyway. It was a lot easier to fit than i thought it was going to be but the joints seem to be a bit sloppy, and i think even after its first ride it might of stretched slightly, but that could of been the chain tensioners, it sometimes happened with my old chain.

On the plus side the bike feels nicer to peddle, and the free wheel runs a lot smoother.

Perhaps if i wasn't esperate to ride today I'd have waited and got a decent standard chain. thanks for the infoate='Jan 12 2008, 09:15 AM' post='1458105]

They don't really feel 'springer under load' simply because the steel used isn't particularly elastic or anything like that. They stretch like buggery though because of the shape of them, they just pull straight-er over time. It's not noticeable at one point though, so you wouldn't do a gap and think "f**k, that's another 1/4" on my chain length".

You can run a single link from one with a Kool chain to act as a regular half-link. Individually they're not bad, and you can replace them relatively frequently if you get a couple so you won't really notice the stretching. Just be careful breaking and rejoining them - the pins lose their mushrooming very quickly, meaning they're not as strong as they were originally.

Every Collapse I've had has developed stiff links, the rollers almost all cracked, and they all snapped relatively quickly. Not ideal.

Nah, it is just the chain stretching. It slows down a little, but yeah, they do keep getting longer and longer. Just keep an eye on it.

I've had a couple of stiff links but they've worked out eventually and never caused a skip. KMC I'm not really a fan off and the one half link I did own has put me right off them.

What chain do you recommend then for ultimate strength?

If you're running singlespeed, Loophole.

If you're running gears, I'd probably get the thin Kool chain and just get a new one every 1.5-2months. Only way to be safe :P
