When deciding whether to start with upgrading the front or rear suspension, consider what aspect of the suspension you want to improve first: handling and control, or comfort/ride quality. Our AXEO Front Fork Cartridges focus on enhancing handling, while our rear suspension products aim to improve ride comfort.
Since about 80% of handling comes from the front suspension and 80% of ride quality comes from the rear, upgrading the front improves handling, and upgrading the rear enhances ride comfort. However, each upgrade significantly improves both aspects of the suspension.
Choosing to upgrade only one end may highlight deficiencies in the stock suspension on the other end. This doesn't mean there's anything wrong with the upgrade; it's just that the difference becomes more noticeable.
