How do the handling characteristics and stability of the Ribble CGR AL change when switching between a drop bar setup for road riding and a flat bar setup for commuting or off-road excursions? Has anyone experimented with both configurations and noticed any significant differences in the bikes responsiveness and overall performance? Additionally, are there any reports on the impact of tire choice and pressure on the comfort levels and communication of road feedback when riding the CGR AL on a variety of surfaces? Specifically, how does the bikes aluminum frame absorb vibrations and transmit power when running wider tires at lower pressures versus narrower tires at higher pressures?
