This is a great idea - I love the maximise hills option :) It reminds me of one of our clubs TT routes which featured 1100M (3600ft) of climbing in 28miles, this would be great for generating some similar routes I reckon.

Yeah exactly. I always ride around wanting more hills in my routes but no route makers have a maximize pain button :) so this was my solution. I've been working on it for about a year and a half

Ti is difficult to weld - there are a lot of cracked Ti frames out there - often at the welds :( A shame as they (can) look great.

I thought about exactly this when I saw this headline. Extra bandwidth just means we can have video header images rather than a still. Here, have a few more tracking scripts.

I don't think they ride Eau Rouge, but Spa is sometimes used for some elite level Cyclocross: https://www.velonews.com/news/cyclocross/gallery-spa-francor... The grass bank climb is incredibly steep.

I know that Castle Coombe has regular bicycle races - both criteriums and time trials. Pretty sure many of the circuits do, as its a good way to use the track and get some cash in, as they are often regulated in the number of motor races due to noise issues.

Yes - very true. I race timetrials and keeping a stable aero position requires effort and practice but it's worth it as the gains from aero improvements can be huge.

There is also no mention of fit changes. Changes in crank length, saddle height, hip angles etc all can have quite considerable effects on efficiency

Double check the crank length. Many of the things you list have to do with bike fit, which I do agree can be wonderous when it comes to feeling comfortable on a bike. But testing various crank lengths I believe didn't have a huge effect on performance. It came down to "whatever you like". I ran a 165mm crank for the longest time, until I realized it was actually a 175mm. But in my head, I always thought the crank to be somehow weird and different. It wasn't! If you're short, maybe a shorter crank length, if you're talk, maybe a longer crank length. Maybe.

There are plenty of muscles there, they just are not shown on the simplified diagram. Transverse abdominus and obliques.

Another vote for deadlifting here. With a desk based day job and being a keen cyclist my posterior chain muscles were under-developed compared to my quads etc - deadlifting helped strengthen my glutes, hamstrings and lower back significantly and pretty much all of my back pain has gone.

I didn't use a coach, but did study a lot of videos on deadlift form and also videoed myself to check I was doing it properly.

Gates only quote between 95-98% efficiency. You can relatively easily get to 98% with conventional chains using wax and oversizing chainrings and sprockets and you don't need to worry about splitting your frame to replace them...

This is a very niche product but sounds like an interesting approach. The users of it likely won't care if it needs replacing every ride if it means saving watts and winning (olympic) races.
