Scot Nicol, Ibis founder and trials enthusiast, made custom trials bikes in his Sebastopol shop, and eventually was able to also have quantities of trials bikes made in Japan and Taiwan. When production split, the bikes made in Japan were called the Trials Comp while bikes made in Sebastopol were called the Trials Pro. They were available with either 20” wheels on both ends or a 24” front and 20” rear wheel. The 24” front was supposedly easier to get over obstacles. Mike Augspurger, co-founder of Merlin, made the magnesium bash guards on the downtube.
