If your baker is a seasoned biker and your pro rider is Evenepoel, yes the baker would be a better coach. Hands down. Not trying to be funny, just stating simple facts. What i do think is funny is that you keep bringing up and muddying the discussion with things like "the dominant hand" which has absolutely ZERO relevance to how you judge a corner and pick your lines. Now you come up with some other phantom argument. I think Remco has been riding with other people and has been watching their lines for 7 years now and clearly it isn't working. Assuming he is not mentally challenged, i believe nobody has ever taken the time of simply explaining to him how to take a corner and what exactly he is doing wrong, simply because they teach you this stuff 10 years before most turn pro. Except, he took a different path and everybody assumed it was ok. So no, i doubt your solution is helping, because that is exactly what he has been doing with zero success. There is a theory behind cornering which he clearly does not understand as he keeps cutting into his corners completely wrong. It has nothing to do with "many factors preventing you taking the best line". He does it when he's riding solo, in TT's on descents, when he's leading the bunch...
Except... not. We are talking about a rider who is missing the absolute basics of cornering. Could you point out to me all the different factors that were impeding his judgement of the corner Berniece posted yesterday? He attacked, he overtook Almeida before the corner, he was leading the race, there was nobody next to him, there was nobody ahead of him, he had a clear view of the corner, he completely blew it and steered into the corner far too early. In fact it was Almeida who had the obstructed view with Evenepoel ahead of him, yet Almeida took the corner perfectly and overtook Evenepoel coming out of the corner, because Evenepoel had to hit the brakes to avoid crashing out of the corner. Same thing each and every time there is a downhill. Last year, he came over the top of Galibier about 10 seconds after Vingegaard. He was solo. By the time everybody reached the valley the gap with Pogacar and Vingegaard had grown substantially and he was caught by the guys chasing him. Which were the different factors then that made it more difficult and different from the other riders taking the exact same route?
Same with his TT's. Last year in the final TT, he lost some time to Pogacar on the climbs, but he lost the most time in the descent. Actually in the first TT it was also in the descent that Pogacar was able to take time back, and now two days ago, he again lost time to Pogacar in the technical part of the TT, there was nobody ahead of him, he did not catch his 2-minute-man (Skjelmose). Please point out how him taking those corners like a grandma has anything to do with not being able to ride the best line.
We are not asking him to become a BMX rider. But for his own safety and his career results, it's imperative that he learns the basics, as he clearly does not understand the theory behind cornering. Because it IS in fact a theory, regardless of what jmdirt wants you to believe, that can be taught even at a later age. Proof of that is in the thousands of people that learn to ride a motorcycle as an adult without crashing out of corners left and right or without prior knowledge or being a professional cyclist. Why? Because when you take motorcycle lessons these things are actually explained to you.
In his first year as a pro, he rode Adriatico Ionica. First stage was a gravel stage. He crashed a few times and lost minutes in GC. A year later he rode his first Giro. We all remember the gravel stage, right? In that time they had done nothing to teach him how to ride dirt/gravel, even though he wanted to defend a GC. Then two years ago i believe, he finally did a gravel race in the US, when he was there for Specialized. During last year's gravel stage in the Tour, you could see he made immense progress. Specifically training on a weakness, especially when you are missing the basics because in his case he was kicking a ball instead of learning how to ride a bike, is simply the only way to improve. But people keep acting like it's no big deal, keep ignoring the elephant in the room. He loses time in TT's he loses time in descents, he loses opportunities, he has to compensate by spending more energy etc... This is his 7th year as a pro. I think it's time to realise he isn't going to improve unless they put in the work.
