This HULKYBOY is the SOFTY of the tough ones. For even better performance in extremely hard terrain, we provide our HULKYBOY now with a new rubber compound.
This special/soft tyre offers a massive grip even on the most technical terrain. Because in addition to the well-known advantages of our 90/100-21 tyre, the incredible, soft rubber compound is now added, making it even more desirable. Especially on wet, slippery, rooty, i.e. difficult technical passages, the new SOFT version shows its advantages.
