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.

Niner’s new Rip 9 RDO and Jet 9 RDO get boosted and plus

Jul 2016

After years of complete dedication to 29ers, Niner is getting in the plus game, as it rolls out fully revised versions of its popular Rip 9 RDO and Jet 9 RDO trail bikes. Both will be available in the usual 2- through 5-star 29er builds. But now you can also order them spec’d with 27.5+ set-ups with max tire size of 3.0”. - Mtbr.com
