Well...you just couldn't be a troll b/c this thread is soooo not creative.
1. Don't buy a full suspension bike under say £600-£800.
2. Look into a decent hardtail with a suspension fork.
3. Where are you located?
4. Why do you want full suspension for "mainly on roads" type of riding...does your community not pay to maintain them?
5. I just wanted to put a fifth point in here to make it look good.
