Wow. 24 posts and no one knows how to fix the problem, just the symptoms. Fancy grips and padded gloves are only good for so long until you adjust the angle of the saddle. You need to level off, or tilt the nose slightly up, to adjust your body's weight disturbition. If the saddle nose is pointed down, you will use your upper body to hold yourself on the saddle in a push up position the entire time you ride. That causes your hands to go numb. Leveled off, or the nose tilted up, you weight is supported by your back and rear, which are the proper parts to support your upper body.
Recunbents aren't a cure, but an excuse.
