The Good: To put it simply, this bike rides like a DH bike but allows you to peddle to the top. The geometry, and suspension design allows you to throw your bike into the gnarliest of lines and come out clean. I've ridden this bike in every environment, from Northstar rocks to fast flowy single track and it's very difficult if not impossible to find a bike that excels as well as the Enduro in all conditions. If you are a rider that likes to haul the mail and can only afford one bike, this is without a doubt it.
2)Ability to plow through anything like a DH bike
3)Built to last. I ride my bikes hard, and have trashed this bike and it's still going strong. After a year and a half of shuttling, lift riding, and local xc riding(which may as well be downhilling as well) the bike has no dents in the frame and only a few minor scratches. The frame bearings are all still good, and the frame has no noticeable flex when riding hard.
The Bad: There are 5 things that I don't really like about the Enduro. Some can be easily changed but some cannot.
1) The cable routing under the frame. This is not really a problem if you don't shuttle, or ever throw your bike over a tailgate, but I really wish bicycle companies would consider this when designing the cable routing.
2)The shock: I debated putting this in the bad category as it does do many things well, but if you are an aggressive/heavier rider, the shock has a tendency to blow through the travel on harder hits(G outs, small drops, big square edge bumps)
3)The offset specialized stem. Over time, the spacer for the stem will decide it's worn out and you will literally be able to flex your handlebars up and down a half inch. Ditch the specialized stem and buy a Thompson.
4)Not coming with a travel adjust fork. This bike will climb much better with a travel adjust fork(Specialized specced the 2012 enduro expert with a travel adjust fork). On steeper climb the bike makes you feel like your riding a wheelie. This is a give and take though. The geo of the bike yields amazing DH performance so it's understandable the way the bike climbs. From personal experience a travel adjust fork will make this thing a much more eager climbing machine.
5) The Specialized seat will eventually start to creak; get a new one. Also, if you are using a Specialized Command Post, crank the bolt that holds the seat in place five times harder than you would anything else, or your seat will self adjust.
Overall, you want this bike if you are a gravity focused rider that can only have one bike. If you have a DH bike and are looking for a trail bike, look for a smaller bike. The only reason I say that is because this bike climbs like a pig compared to other bikes in its class. The Nomad, Ibis Mojo, etc all pedal much better. The tradeoff is the Enduro rides down the trail better. Personally, I will be selling this bike to get a lighter, more XC friendly bike at the end of the year, but that is because I have a DH bike to ride, and this bike creates some overlap in the bike stable.But, in summary, this bike is rad. You will not be disappointed if you buy one.
