2018 was a stand out year for Frenchman Amaury Pierron. Taking the overall World Cup title and riding consistently at the top of his game, there was little debate that he was a contender for the title of World Champion, however, after a long season on top coupled with some sickness, the rainbow stripes evaded him.
This year, a similar stage is set. Pierron has once again been consistently riding at the top and the French have taken six of the last seven WC wins. With three wins and not a single finish outside the top-10 this season himself, he's sitting in second place for the WC overall with just two races left... this weekend's World Championships and then finals.
After missing the coveted jersey last year, there's no doubt that Pierron is hungry for the win this weekend and he is no doubt a favorite to take the top step.
Pierron has been on the same bike for several years but each season, things have changed a bit. He's still rolling with 29" wheels front and back, steering clear of the mixed wheel size we're seeing some racers running, for the time being.
This season, Pierron has gone from aluminum handlebars and wheels to carbon parts from ENVE. The set up took a bit to get used to at first due to the increased stiffness and he's running somewhat softer suspension settings to help the bike feel similar to his ride last season. He doesn't know what his exact suspension settings are but he runs things "balanced front to back."
The bike has had a new rear end on it since Fort William. The change makes the back of the bike feel stiffer, according to Pierron, and he feels that the energy transfer is better now, especially when pushing the bike into rough sections of the track.

I am pleased to report that 1.8 bar = 26 psi
60% of the time it all makes sense
We measure our fuel in litres and our distance in miles and our fuel efficiency in miles per gallon
Our land is in acres and floor space for commercial buildings is square feet but if its residential its square meters
Our food is in grams and kilos and people measure their weight in stones and pounds and our body height in feet but our beds are in meters ????
@SonofBovril - Imagine so, but what about the anti squatz?
Unless you are basing your question on something I'm not seeing. Why do you think this rear end woudl change AS ? They don't really say what changed about the rear end except power transfer is better. I suspect the pivots did not change or anything like that, its just thicker aluminum or otherwise stiffening up the rear sectoin.
I’m not sure you have a good grasp of anti squat?
They've been playing with the idler position pretty much since the beginning of the bike, or just after the couple of first few races.
I have a commencal high pivot and yes there were two changes on the team bikes. The current rear triangle can be a bit flexy as most of the work is being done by the upper tubes while the lower (chainstay) is leveraging the suspension. The new design does a better job spreading the lateral force out across the entire triangle and this improvement has been mentioned by team riders.
Moving the idler up,down & back and forth changes anti-squat and when/how that AS occurs. Moving the idler below the pivot increases AS as it's pulling the triangle down under pedaling power. Too much and it'll bob from chain growth. Go above the idler and it'll pull the rear suspension up under power.
