I've used JB Greens and GB Cypres Extra Leger on my Roadeo. The GB's are noticeably lighter and more flexible with a smoother, more shock-absorbing and vibration-damping ride. They also allow shaper handling due to less gyroscopic resistance in the steering. They feel faster overall and measure about 30mm wise on my H Plus Son TB14 rims.
The JB's are about 80-100 grams heavier per tire and this is easily felt in the steering (gyroscopic force) and effort required to accelerate. The bike becomes more stable and mellow. Less racy. The rise is still quite good at low pressures but not a good a the GB's. The side walls are sturdier and I don't worry about flats as much. The extra inertia from heavier JB tires means the bike is more reluctant to change speed. Slower to accelerate and brake but this also means the bike holds speed well. I don't really feel slower when cruising along at a good clip because of this. They are noticeably fatter than the Cypres EL and look great. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
