hi there! I have an old bicycle, and I'm looking for a new one, but I've been looking for the new features, and I've found the 29er.. It is newness, and I've heard that the 29er's are very good, so I looked for a 29er full suspension, but it's too expensive, so I found the 29" hardtails, and I searched and I found a CUBE Acid 29 (http://www2.cube.eu/en/29er/acid-29/).. But I wanted a full suspension bike, and I found an ROCKRIDER 9.1 but it's 26".. (http://www.decathlon.pt/PT/rockrider-9-1-2011-173319097/) can you tell me what's better for me? Is the full suspension or the hardtail? And if you know about other good brands can you tell me please? Thanks.
