“Observed Trials” by Bernie Schreiber and Len Weed. Probably the best trials instruction book ever written, the 192 pages of photos and tips from the former world champion is still a fascinating read today. Plenty of photos of SWM’s and other brands and riders from back in the day. I have been lucky enough to find the last few remaining new copies that have been in storage since 1983. There re no plans to reprint, so when they are gone, thats it !!!.
Please note, covers have slight damage from 35 years of storage.
