Interesting article. And as a long-time PowerGrips user, I'll have to admit I'd never seen the 1.0 version until that ad on the last page.

Rad back then. Imagine sailing this bike in cross winds.

Side note; His brother Brent was innovative too with monocoque mountain bike frames. Before front suspended forks, he made a hardtail full carbon frame shaped like an 'X'. I had a later design with elevated chainstay, and a first MTB by Kestrel. He might have been making these as well. It was heavy but for a rigid, soaked up rough stuff compared to light steel and gave a confident ride.

After that was the more conventional diamond frame with wishbone seat stay, yet full monocoque. Called the CS-X. I know that one too was Brent Trimble design but apparently there was a business relationship with Bevil Hogg / Kestrel. I suppose by then it was all Kestrel produced. Had Tom Ritchey steel uni-fork and Ritchey Logic labeled parts; (Suntour XC-pro and Dia-compe).
