I ran into a buddy of mine on a ride a few days ago and he was riding on his new carbon wheels. We climbed this road that has about a 900 ft descent from the top. His wheels started putting out an awful smell and he said that the rims were real hot. Tomorrow he plans on doing the RAMRODhttp://redmondcyclingclub.org/RAMROD/RAMROD_course_information.html having really never descending on these wheels. I am no carbon wheel expert. Do they normally emit a burning odor and heat up like that? New equipment before a big ride can sometimes end badly.
