I will retain 2
possible watts at 440 w assuming that the SKY is equipped with it. For the chains, you will need a new chain, broken in and ideally sorted upstream on a measuring bench because as I demonstrated
here , you can find 2 watts of difference between good and bad
chain from the same manufacturer at 250 w. Wiggins had all his chains sorted
to keep only the best for his hour record. At 450 w, this Oversized vs. can represent 3.5 w!
Chain performance of different series/manufacturers
Last point in my opinion which can be important,
rolling resistance. Many teams are equipped with Continental Pro
LTD. They have certainly evolved since
2012 when we see the progress of tires and rubber on
rolling resistance in 5 years! We could possibly
weigh the equipment and also put aside the c level executive list lightest ones therefore Oversized vs. presenting
a tread not too thick… we imagine that the equipment is already
optimized. Despite everything I remind you that 20 g more for the same tire (5%
manufacturing tolerance) can add 1 good watt of rolling. The widths of the tires/tubulars as well as their resulting pressures have also evolved. We know today that there are pressures not to be exceeded called dropouts (especially on mountain tarmac with rough passages).
Stall yield vs pressure vs terrain
will therefore be necessary to find the best compromise between tire for the terrain, weight of the
rider, habit of the rider (dancer therefore pressure to how we can make websites carbon-free adapt on the front). I remain convinced that since 2012, there
are 3 to 4 watts saved on the rolling resistance in its entirety and at 21 kmh for a team like SKY. Small aside with the granular ground in the mountains… On the graph above (source Tour Int) we
can see that a pair of reference tires like the GP4000S 2 25 mm loses 10
watts at 35 kmh between a smooth tarmac betting email list and a rough ground while the Michelin
competition only loses 7! Here
too it can be interesting to choose the right tire according to the type of
bitumen.
