I'm new to road riding so bear with the newb question. When I have done mountain biking I haven't worn long riding pants even in cold or wet weather (e.g. 40 degrees and raining). Due to the higher speed of road biking, are tights necessary or just preferable. In other words will I be able to feel my legs after 1.5 hrs in 30 degree weather at 20 mph or so? If so, where is a good place to start looking, bear in mind I'm on a rather tight (no pun intended) budget.
thanks
