Finally, there's a tire specifically made to withstand the demands of indoor riding on a trainer or rollers. Continental's Hometrainer is built to handle the heat and friction the trainer's roller puts on the tire so that you can ride with minimal tire wear and save your regular Contis for ruling the pavement. This tire is only for riding on a trainer; not for outdoor use.
