Brunson Grothus

The standard formula for a Pro Ultra 4.60 index bike is to take an older Pro Mod, something somewhat less competitive than Grothus's, and dial it down to hit the number in the eighth mile. Courtney Wheeler took the other route, starting with a small tire Top Gas bike and juicing it up.

In NHDRO's first ever 4.60 final, Wheeler met up with Les Stimac, who rides Jeff Lindeman's bike. Lindeman's Suzuki has a long history, even adding weight and running Funnybike years ago in AMA/Prostar races. This is exactly the kind of bike that 4.60 is designed for. But Wheeler showed that Top Gas bikes can work too, taking the win when Stimac -- who took the tree -- broke out by .003.
