If you're training strength on the bike by overgearing, just remember to do overspeed work as well, including in your race gear. This can be motorpaced "overtakes" (sprint past the bike), or find a flat with a downhill leading up to it that allows you to sprint 5-10 kmh hour faster than you would under your own power on the flat. Try to hold the speed in your race gear as long as possible, as soon as you drop down to your own intrinsic top speed, back off.
