2005 Trek, Mavic Kysrium SL Wheels, Michelin tubes. The last two times out on the bike I have been caught out in a rain storm. My wheels get water inside of them. The first time it happend took off the tires and cleaned and dried the inside of the tire. Went again and was rained on again ended up with water in the wheels again.This happens to both front and rear wheels. Took of the tires and had about 2-3 oz. of water in the wheel/tire. Just put on these wheels less than 200 miles on them. Should I seal around the presta valve? Has anyone else had this happen? Searched and could not find anything on this subject. Thanks in advance for any help.
