Buying a new bike should be based on where are you going with trials. Are you very competitive? Young or old? Goals are to improve fast? You ride a hard line and hop a lot. Do you plan on keeping the bike till the next model comes out or five years. New they are all good bikes, but built totally different. Take a good look at yourself, not necessarily the bike. The Vertigo is the new competition only bike, the Sherco is more of the same, but really improved. The Montesa is a whole other type, great build, fun to ride and known to last. Will do anything it is asked, capable in the right hands, but more of a clubman bike.
