@@russellmoore1533 that makes sense, that footbox dimension drives aerodynamically significant geometry. I also recently saw from a Dylan Johnson video summarizing the science of crank length on power generation and efficiency and surprisingly shorter cranks is not detrimental to either metric until you go really low, 125 - 150 mm.
@@edwardnowill4408 @jucaesar4961 Oh wow so that means these kind of bicyles are actually slower ? Impressive I'd expect to see them at least at world champs if they were not
@@alpha7440 I'm not sure if I have understood your reply.The whole point of racing human powered machines [in its broadest sense] is to see what works best/what type of mount goes fastest for the fewest watts of human input.
I can't find them on there! They should be listed under Racing and Results, but it doesn't contain any results for me, nor are they anywhere else. Can you see them?

Crazy high cadence Russ. Is that on purpose or were you running out of gears?
It's just where I produce the best power. And you tend to run a higher cadence with shorter cranks (145mm)
@@russellbridgewhy not use bigger cranks?

That only got you 8th??? haha I would have guessed your average power was higher. I guess the soft-pedaling through some of the turns dragged it down.
human powered vehicles ? What would stop one from bringing a time trial bike there and take first place ?
Nothing.
BHPC welcomes riders of all types of bicycles-bring yours along & compete with other BHPC members.

@@edwardnowill4408 I understand that. I just thought pro time trial bikes would be faster than any other vehicle for this kind of event
Where are the official results published? Are they out already?
results at wc2024.bhpc.org.uk/ - I think that they are still provisional at the moment

Can you see them?
@@jucaesar4961 yes I can see them on there - go to 'racing and results' and then 'results' and then click on the relevant race
Thanks! Somehow they were visible now...
