100 Link Chains

Postby Rik on Tue 17/Mar/15 11:07am

Are they a 100 links including the split link ie. 99 + split link
or 100 links plus split link ie. 100 + 1?

Unless a half link is involved, wouldn't all chains end up with an even number of links?

Nope.

Pretty rare instance to be so close to needing exactly 100 or 99 links.
Just get a longer chain.

1 link = 1 narrow + 1 wide.

Half link chain combines the 2 into 1.

Your right it must be an even number with the split link, so the answer must be a 100 link chain has 99 links and a split link.

I hope it's that simple. Let's say the chain has 50 sets of outer plates (one of which may or may not be a joiner). With 50 sets of inner plates it will have an outer on one end and inner on the other, so will work.

Now imagine the chain is powering a treadmill, and we have 50 outer and 51 inner plates. That leaves inners on each end, so it can not be joined to make a 101 link chain. This design will not fly.
If we add a joining link, that makes an even 102 links. But maybe we have to consider the rotation of the earth too?

But then a "100 link" chain would be 2.5m long, which they most definitely aren't. ;)

A 100 link chain intended to be joined with a push pin will have 50 thick links, 50 thin links. The thick link on one end will have a pin in it that you can push into the thin link that's on the other end. 100 total, when on the bike.

A 100 link chain that is supplied with a quick link will have 49 thick links, 50 thin links, and one quick link - joining the two thin links on each end of the chain. 100 total, when on the bike.

If you only have inners on each end but then you tie some string onto the bit hanging from the bottom of the derailleur and then hold the string then you can pedal a little bit and then use the string to pull the chain back when you backpedal and then you can pedal a little bit more and if you do it repeatedly then eventually it will fly. You'd need a freewheel on the treadmill though.

if you use elastic then you do not need to pull it back, you will need to back peddle though. a 2.5 meter chain would help with this if you had something to take up the slack after it comes off the front chainring.

if the chainring was actually shaped like a spring except with teeth around the outside then you could attach the chain to one end of the chainspring and you could peddle like 5 times around and it would just wind around it until you couldn't peddle anymore because of the elastic

then you cud take off faster

Why you want 100 links? You're taking OCD/the metric system a bit far there maing.

But will a plane take off from that treadmill?
