The standing start is key to the 500m. You cannot nail the standing start if your bars are too close. You’ll be constricted, like changing clothes in an airplane bathroom.

Both the Keirin and 500m are less 1 minute each (if you don’t count the paced windup of the Keirin). Don’t look for comfort on the bike in those events. Look for aero gains and power production, at the expense of comfort.

Learn from my mistake. I spent SEVEN seasons riding 56-58cm bike...when I should have been on a 61cm.

I have a lot of real regrets about that. When I trained my hardest, I was on the worst fitting bikes...and vice-versa. And the times and speeds were similar. Imagine if I had the right fit early on?

Do not get hung up on numbers.

Read that sentence again.

Just add more when you need more and remove when you need less. Declaring what sizes you are and are not can be a huge problem. It was certainly in my case.
