I just got my first bike that has a carbon frame and a few questions have come to mind. First off I got a Raleigh Talus 29 Carbon Elitie. Using my t-wrench I don't seem to be able to tighten my seatpost clamp tight enought to get the seat to stop moving, is there anything I can do to tighten the seatpost down without destroying the frame? Second it gets cold during winter here and I was wondering how the colder temps can affect the carbon frame? Am I able to ride during winter or does the frame become to britle? Is there any else I need to know about carbon frames before summer comes and I start really riding this bike? Thanks for the help everyone!!!!
