The vertical world of bike racks can be tricky to navigate, especially when it comes to finding the right spacing for a compact carry bike rack. At ALTA SIX GPR, we recognized that the lean of the handlebar is what creates the desired spacing, which is why we chose to have multiple size baskets to control the angle and lean of the handlebar. This not only allowed for a better and smaller design, but also created a lighter rack, even lighter than some name brand four carriers.
The issue with general size baskets (one size fits all) is that they can cause interference between bikes with different width tires. Fatter tires tend to stand upright, turning the handlebar almost horizontal to the ground, while skinnier tires lean much more with a more vertical handlebar. This creates problems when trying to fit multiple bikes on the same rack, causing rubs and damage to both the bikes and the rack.
To solve this problem, some companies make their racks wider to accommodate any bike, but this leads to racks that are too heavy and cumbersome, weighing upwards of 100 pounds and being seven-feet-wide. Additionally, if the lean of the front wheel is not correctly positioned and controlled within a small range, it can put excessive force on the hub, rim, and fork, especially in high vibration cases on washboard dirt roads. This can be particularly problematic for high-end carbon rims and TT bikes.
By controlling the lean with three different basket sizes, we ensure that the rack can handle different bikes and forces without wobbling or teetering. At ALTA SIX GPR, we’re dedicated to creating bike racks that are versatile, adaptable, and built to last. Keep shredding!
