I know it isn't the first time I've asked all of you which one would you preffer but it will be the last. I've came down to these four bikes that are around my budget and are available on the local shops. All suggestions will be much appreciated. Bike will be used for everything.
GT KARAKORAM 29 COMP - 2016 - Karakoram Comp - Trail HT - Mountain Hardtail - Bikes - Around 500 euros
KTM ULTRA FIRE - KTM BIKE - - 722 euros
ROCKHOPPER - Specialized Bicycle Components - 549 euros
CUBE ATTENTION - CUBE Attention blackīnīgreen 2016 - 671 euros - ( Only 27.5' available )

In terms of wheel local dealers have been telling me that 29' is now the thing and will probably suit me well so the cube bike might be out of the list..
Thanks for everything, Miguel Neves

I got a chance to ride the rockhopper. I really like it. The others I have no input.

Marin Muirwoods 29er or Giant ToughRoads 29er.

If you're looking for a 29er with a rigid fork and all-round ride.

Miguel, where are you at? What brands are available where you are?

Portugal, Brands available: Cube , Specialized, GT, KTM
