OK, here's the deal. I'm out trying to ride 6 days a week to get back into shape and loose weight. I am only riding about 45 minutes a day. My route is slightly hilly so I feel I am getting a decent workout. I have a 2007 Allez Expert that was professionally fitted at my LBS. I wear a pair of Specialized gloves. Around the half hour mark my hands start to go numb. I will change positions and shake them to bring the feeling back but it is damn annoying all the same.

The bike fit seems to be great as far as I can tell and my hands went numb on my old bike too. I 220 down from 229 a few weeks ago. Is there anything I can do? I'm not sure if it's my weight, gripping the bars too hard (I try to have a really loose grip) or that's just the way it is going to be for me.

Any suggestions?
