1do you think the word snurfer was the original name for a snowboard, or for a pair of skis? 2 which is more popular: snowboarding or skiing? 3 if you do cyclo-cross, do you ride your bicycle on roads, or across the countryside? 4 how are mountain bikes different from road bikes?

1.Snowboard
2.Skiing
3.On roads
4. Road bikes are lighter then mountain bikes. Road bikes have much narrow  tires (compared to a mountain bike) with much higher pressure. Road bikes go on roads and mountain bikes go on mountains. Надеюсь
