Ride BMX UK april 1994: Kris Gack's company Gack Street Bikes is picking up speed: sealed hubs with 14mm axles, big pegs, and flip flop stems are available right now [pricey but worth it], with more product coming in Spring including Monkey bars, the Streetbike frame, and a new BMX frame called the Ridehard - a lighter race version of the Streetbike with flip flop stem, oversize headset with pressed-in bearings, etc etc. Also, word has it that Kris will start working for Hoffman Bikes as new products designer, and may move to Oklahoma City to work from there with Matt - Gack Street Bikes will then operate out of OKC.
