Niner Jet 9 RDO XT 29 first ride review

Jan 2017 · Guy Kesteven

The Jet is still an XC rather than technical trail oriented bike at heart though, with organic-looking big volume carbon main tubes squeezed in to shape with Niner’s high fibre/low resin concentration Carbon Compaction System moulding.

Niner introduces 2017 Jet and Rip, and goes 29..ish?

Jul 2016

If you’ve ever read anything about Niner, you know the company’s loyalty to the 29-inch wheel. So it goes without saying that offering 27.5+ versions of the 2017 Jet and Rip models is a bit of a surprise - to say the least.
