What would be the most unconventional yet functional custom build configuration for a Canyon Grail AL 7.0 that would still allow it to excel in its intended gravel and adventure riding disciplines, and are there any limitations or potential drawbacks to consider when pushing the boundaries of customization on this particular frame? For instance, would installing a singlespeed setup or a Gates Carbon Drive system compromise the bikes versatility, or could it actually enhance its performance in certain conditions? How about swapping out the standard drop bars for a set of Jones H-Bars or a drop-bar/mountain-bar hybrid, and what kind of ergonomic and handling implications might that have? Similarly, could a custom build featuring a Rohloff Speedhub or a Shimano Alfine 11-speed internal gear hub be a viable option for a rider who wants the benefits of a geared system without the complexity and maintenance requirements of a traditional derailleur setup? What about integrating a set of 650b wheels with high-volume tires, and how might that affect the bikes geometry, handling, and overall performance? Are there any creative ways to optimize the Grails cargo-carrying capabilities, such as adding a custom rack system or using frame bags and other soft luggage solutions?
