Hyperpro makes a full adjustable rear shock and they also have a replacement spring for the front fork. They used my bike for measurements. I've tested the rear shock for some 1500 km now and it's just perfect! The front conversion was done a few weeks ago, so not tested for many km's. They have also replaced the forkseals for SKF ones wich is also a big improvement. But definately performs better than stock, steers sharper and dives less when braking. Both Hyperpro springs (front and back) are progressive. Bike's are still under construction for our RTW trip. This is one of them with our prototype rack.
