I have a B'TWIN Rockrider 520, a 27,5" hardtail with aggressive geometry and amazing handling. It is everything I could have asked for, since it's good for trails and for street. However, it comes with a 80mm fork which (for me at least) is way too stiff. My friend has the same bike with no upgrades on it and his fork is fine, but mine requires a LOT of force to compress, no matter how low I set the preload to. I'm not such a light guy, so that is definitely not the issue. Do I have to buy a new fork or is there something else I can do to help with this?
