Someone at the Barber Vintage Festival was selling this very nice looking frame a few years ago and I thought it might make a good basis for a trials bike project. I waffled and someone else bought it. I had never heard of an RTX but apparently it was a playbike made in the mid-nineties and not well thought of. From the Trials Central forum: "They were designed and assembled in Britain, from parts manufactured in Belarus, Taiwan, Japan, U.K., Germany, India, and Latvia. They made both twinshock and mono/disc brake bikes."
