I crossed over from downhilly stuff to a trail bike about a month ago.
I went with an Orange Five, simply because I saw one that was cheapish, the right size and I had previously had a Patriot 66 (It wasn’t a great bike, but I thought the five would be better).
I’m really pleased with mine, it’s very happy at high speed, fun to ride, and very very fast as well as being more fun then my patriot. Mine is a more enduro setup and weighs in at 29lbs, with 150mm forks.
Overall I love it and I’m a much better and more precise rider since I downsized. However, that might be me more than the bike. The rear shock also can be a bit hit or miss, it depends on tune and weight tho.
If you are taking weight seriously though, I’d go for something carbon, you can get much more bike for your kilo that way, so maybe a 146 may be a better option, it seems like a fun bike, although apparently the rear end is a bit flexy ?
To be honest, I can see Orange getting left behind in the near future, and I may not be buying another aluminium filing cabinet from the Halifax boys again if carbon bikes start performing on par with the Five.
