Reminds me of the old Benson & Hedges commercials. Anyway ever since I got my Madone I've been suffering with hand numbness. With my Trek 1600 it didn't start to set in for at least 45 minutes, then I could just shake it out and it would be ok for a while longer. With the Madone it starts around 15 minutes into the ride. I tried raising the hoods just a tick, I flipped the stem trying to see if getting me up a little higher would solve the issue but no luck. I was starting to wonder if I destined to riding this bike like this for ever.
I have been noticing the bar tape already starting to pull apart around the corner part of the bars just above the hoods so I decided to get some new tape and get rid of the Bontrager tape that came with it. Then it occurred to me to maybe double up the tape. So I put a band of electrical tape around the stock tape right at the hoods, rolled the hoods up and cut around the old tape to remove it from the hoods down leaving the stock tape across the top of the bars. Then I wrapped the bars with new Specialized tape all the way and covering the stock tape. Went out this morning for 55 minutes and NO numbness at all...none!! I'm not sure if it's the extra thickness or the extra softness but it works and I will be doing this from now on. It took me a while to suspect the tape since it's the same tape, and bars for that matter on the other Trek that I have with much less numbness, but apparently that was the answer.
Just thought I'd share...now they can move this thread to the Road Bike section or maybe the mechanics section.
