I got a Trek 4300 a couple of months ago. My friend has a diora bike with slick tyres. and i'm just wondering what they would look like on my bike. she goes alot faster and i find it hard to keep up as her wheels are alot bigger. my bike size is 18". i got the trek as it was comfortable for me as i have a back neck/bike. i can't do any sports that have an impact on my back so i have started cycling just for fun! i really enjoy it and it is great for keeping the pain away in my back as i'm moving! anyway i'm thinking will the slicks make me feel the road more?as the tyres i have on my bike are big and knobby for off road i guess. i want it to look trendy and look good on the road. i'm not going to be taking i off road at all. just want to know if it would be ok and whether it would look ok. any pics links would be great to see.
