Front or rear?

So, why do we always need to sit close to the front of a group? Is it because there’s less crashes or is it better for climbing? Believe it or not, it’s less effort…

Riders near the back often have to close gaps if a rider in front of them fall off the pace.  They also suffer the "slinky effect" going through corners where they are required to decelerate into a corner and quickly accelerate out of the corner to keep up with the group.

Some data have been collected at this years Nature’s Valley stage 1, a circuit race. One rider managed to stay close to the front while one of the riders was 100+ back in the field. After the race they managed to analyze some race data and it was very interesting to see the difference from being close to the front or near to the end.

Some of the data collected:

Steve Scholzen was close to the front, being the teams designated sprinter.

Matthew Busche was nearer to the back of the field

So there is more to being close to the front than we think…for more info and some stats please visit http://www.saris.com

Very interesting - no doubt that sitting at the back requires more effort..
