Bitubo MFORK Fork Springs Kit Progressive + 1 Lt. Oil

These progressive fork springs from Bitubo are made from high-strength steel, a material chosen for its ability to handle the stresses of the road while maintaining its shape. Unlike linear springs that have a constant rate, progressive springs change their stiffness as they compress. This means they start softer for a more comfortable ride over small bumps and then get stiffer as you hit larger impacts or corner harder, helping to keep the front end stable. This kit also includes one liter of specialized fork oil, formulated to work with these springs for optimal damping performance.

Bitubo has designed these springs to offer a noticeable improvement in how your bike handles. The progressive rate helps reduce brake dive and squat during acceleration, giving you a more balanced feel. This can make a big difference in confidence when you're riding, especially on varied road surfaces or during spirited riding. The included fork oil is specifically matched to the spring rate, ensuring you get the intended damping characteristics right out of the box.
