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 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

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.

There is a slow movement to using stack and reach for frame sizing, which are the two most critical measurements for bike fit.

Stronglifts or starting strength

Greyhounds make great pets btw. We have rescued 4 ex racers and they have all had the gentlest, lovely temperament.

They don't need loads of exercise (contrary to most people's belief) - in fact they are often referred to as 45mph couch potatoes...
