I remember hearing Callum Skinner talk about the British track team preparing for the Olympics, and how the biggest problem they had was strength - I remember the number 2400 for their best track sprinters, I forget if that was in watts or newtons but either way it's a massive force and they were snapping frames.

The discipline of cycling that's the most weight-motivated is hill climbing. Track cycling really doesn't have that as an issue, and definitely does have a materials strength issue, so I'm not shocked they're not building to a weight limit.
