US manufacturer Niner, which specialises in 29ers, has been offering the R.I.P. 9 for five years, and despite its timeless look, you can tell. Compared to its brand-new competitors, the pioneer looks aged, the frame lacks a closed cable routing and thru-axle, for example, but it has the absolute highest stiffness (tip for tall, heavy riders) and the top tube is long. This gives the riding position a sporty feel and makes it easy to get uphill. The shock platform tames the VPP rear end, which is not quite drive-neutral. The fork puts a damper on the handling, which is very good in principle. It only works comfortably in the mid-range, but when it comes downhill, it lacks reserves. It would be interesting to try a 130 or 140 mm fork, which would also flatten the steering angle in an all-mountain style. If you only buy the frame, you have a free choice anyway. Another thing I noticed: The double cranks lack chain tension, a guide would at least be helpful for AM use (or a special trail derailleur).
Conclusion: a special touring bike for technical trails, but not a racing machine. Best as a custom build.
PLUS Sporty handling, good wheels
MINUS Translation, relatively expensive
