The 2021 XC World Cup season burst into life in Albstadt this evening with the opening short track race of the year. It was a cold and snowy start to the day, but by the time the on-track action kicked off it was dry and sunny, leaving riders and mechanics pondering last-minute setup changes. With such fine margins, every detail counts at this level, especially with the frantic and fast-paced nature of short track racing.
It was two familiar faces who opened their account with winning ways in this crucial run-up to the Olympics, with Pauline Ferrand Prevot and Mathieu Van Der Poel being the cream of the crop after managing to just about break free of the chasing pack. Linda Indergand broke free from the pack for a while with a brave and gusty ride before ending up second, Annie Last followed in third with Kate Courtney and Loana Lecomte rounds out the top 5.
The front of the men's race was action-packed with a lot of chopping and changing, in the end Van Der Poel got the better of the competition with Victor Koretzky pipping Nino Schurter to the line in a sprint finish, in behind them were Henrique Avancini and Mathias Flückiger.
The U23 races take centre stage tomorrow before the elites are back on track with Sunday's main event. Who will draw first blood?
But anyway doesn't look that tasteful
Here you can find more about the gold helmet...things that matter for sure hahaha
The rules about using the same bike for both XCC and XCO really only apply the frame. I have to wonder if it's because mechanics don't want the hassle of switching tires for one day, then switching them back, or if team budgets are really that tight, they're stuck with whatever sponsors provide.
I was thinking the same. Earlier in the day, when it was snowing, it looked as if it might have been a mudbath - you would surely go for maybe a mud tyre, and/or a narrow tyre to cut through the mud.
However, it stopped snowing, and dried out - so mud tyres weren't really needed.
It's all about contact patch causing casing deformation. Assuming equal tire construction, when using equal pressures between a narrow and wide tire, you have the same exact amount of surface area in the contact patch. The difference is that with the narrower tire, the casing has to deform in a more longitudinal direction to get the same contact patch (lots of casing deformation), whereas the wider tire has more width to get a more latitudinally shaped contact patch (less casing deformation).
Aerodynamics are another factor the wider tire movement in road (better transition between sidewall and rim), but that's another story.

No one is running 28c tires at 120psi. Most people are probably running them at 80PSI, which the testing shows 25c's @ 100PSI and 23c's @ 120PSI to be faster than the 28c's at 80PSI. I am 6'2'', 190lbs and run 95R/90F on my 28c Grand Sports.
The world's top female athletes that are petite sized have even less incentive to run higher pressure.
In any case, to clarify, shaving doesn't "prevent" any injury, it just makes treating the inevitable injury suck a little less.
