How to save 30 watts of drivetrain losses using only your chain! aka Friction Science in 8 steps

How to save 30 watts of drivetrain losses using only your chain! aka Friction Science in 8 steps
Here we examine how serious riders can save 30 or more watts in drivetrain losses by paying attention to their chain alone! In truth you can only “limit losses” and never truely gain watts because every bike loses watts / power in the mechanical parts. If you made all these mistakes we estimate it could cost you 34w. However by paying attention to these 8 steps you could turn -34watts into only -4 watts of losses. This could be very important to timetrialists looking for marginal gains. If you want to look into these drivetrain losses in more detail I recommend: http://ift.tt/28UfNty. Also search velonews for other articles on this topic.

Here are the tips one by one
1:30 Quick clean on the bike (12w)
1:43 Quality manufacturer (5w)
2:07 Chain length (4w)
2:35 Cross-chaining (3w)
3:10 Chain specification (11sp) (2w)
4:32 Chain wear (2w)
5:15 Deep clean off the bike (1w)
6:06 Super lube (4w)
