Fork stiff spring kit

To increase performance on your Kalk INK, we recommend an upgrade of your fork spring from the current 4N/mm stock spring to this 7N/mm spring. This 29.2mm OD x 353mm TLG aluminum spring will make your fork significantly stiffer. If you wish to customize your fork to your liking to be even more sturdy, go ahead and buy two kits - for both fork legs. Changing the spring in your forks will require intermediate technical skills, we recommend letting your local specialists do it. The specific tools you need to upgrade your fork springs are included in this kit.
