The Giro had a day when about 8 riders were in a chain and it was a joy to watch. As a rider got to the front he just rode to the side and another rider took his place. You could see why it is called a chain. But a couple of remarks by the commentators made me realise a few rules. The lead rider pulls at 100%- not 110- he does not increase speed or power as he gets to the front. He might have to put more effort as the lead rider but it is one continual "Chain" movement for the group. And you have to know the other riders and trust their capabilities.

The other situation is where you have a few riders trying to maintain speed. Such as where a team are trying increase speed opr catch up with the pelaton. Saw Sky do this several times and the lead rider will put in effort for a long time. 2nd in line will not be working as hard-somewhere around 90% and third is where it gets noticeable as the 3rd rider is at 75%. Each at the same speed so 3rd rider back is being pulled along with less effort. This is why you saw Cavendish holding 4th in line while his team mates were bringing him to the front for the final sprint. That rider on the front will be working hard and if he does it for an extended period- that will be his stint and race finished.
