The latest Michelin PRO 4 comp limited 23 mm in extreme
At this time of year, the weather conditions, often changeable and already
cold, rarely allow for reliable terrain measurements. But luckily, I had
a beautiful, windless day when the thermometer rose to 13 degrees. This is not
the usual 20 degrees for my tests and I was afraid that this Michelin PRO 4 would already affect
the hardening of the tires. Nicolas Crêt, an engineer at Michelin, rightly reminded me
Michelin PRO 4 conditions
that we can have an increase (more or less strong) in
rolling resistance with the decrease in b2b email list temperature. The colder it is
, the more difficult some tires become to handle. That said, it is a
general rule but not all tires will vary in the same way. This will be noticeable for significant variations, for example from 25 to 5 degrees! At 13 degrees it is still
representative of temperatures that can be encountered all year round. So I tried the test by comparing it to my best seller of 2013: the continental Supersonic 23 mm.
one tire at 166g, the other at 172g not bad!
The Michelin Pro 4 Comp Limited is the ultimate evolution of the
Pro4 Comp. Even lighter (-15 g), a little less puncture resistant
but announced as the fastest Michelin. As the graph below shows,
the PRO4 Comp Limited retains the genetics of the PRO4 in its tread
with very good grip on dry and wet ground.
Features
I did a warm-up climb with then 2
climbs of 11’40 @ 280w (maximum 6 most common marketing automation pains: part one power at the time that could be maintained for the duration of the
test…), disassembly then assembly of the supersonic then again 2 climbs @ 280w.
And 5 more Salberts for 2013!
As usual,
the SRM is calibrated and the offset 0 is done before each climb. I weigh myself for
each climb and thus I can determine through a theoretical calculation the
power of the climb that I compare to the SRM recording. I can therefore see
if one tire saves more watts than another compared to the be numbers theory. The
results obtained show that the Supersonic remain ahead but really only
slightly.
