In the early years of mountain bikes, use of toe clips was rare, probably because early mountain bikers felt insecure riding off road with feet strapped to the pedals. Laurence Malone and Charlie were early adopters until others began to recognize the huge ergonomic advantage they provide and that they could be safe. The pedals, straps and toe clips on all of Charlie's bikes are modified for easy, consistent entry and instant emergency escape, even with the straps tight.

Many of the handmade parts on this bike were forerunners of products that became popular in later years. The 7075-T6 cam style seatpost clamp has been adopted by manufacturers and is common today. The stem with its removable cap and the custom built sealed bearing hubs inspired many similar products by CNC machinists and large-scale manufacturers.

Charlie made the 11-38, seven speed freewheel from cogs available at the time and modified each tooth profile to give quick, precise shifting. The bike has a single 41 tooth front chainring. The black anodized brakes were bandsaw cut from 7075-T6 plate and hand filed to final shape. The toggle brake linkage gives accurate and powerful control while being fully adjustable for power level. Overall, this bike is an absolute dream to ride, having been designed to excel on narrow Marin County singletrack.

Charlie raced this bike in several major events in 1984 including the NORBA Nationals in Nederland, Colorado placing 10th overall and first in the over 35 class. This Green #12 contrasts starkly to the bare and battered Cunningham warhorse that Charlie's wife Jacquie Phelan trained and raced on for eight seasons, winning three national championships.
