Matt Connwrote a review of Niner RIP RDO 29 4-Star Mountain Bike - 2019 on August 30, 2019
Familiarity: I've used it once or twice and have initial impressions
When I rode the previous generation RIP 9, I was confused. With the mid-long travel category becoming so popular in the last couple of years, it seemed like a slam dunk for a company named NINER to jump in on this. However, the previous generation was still lacking quite a bit compared to groundbreaking bikes like the Ibis Ripmo. It turns out that the wait was worth it and Niner has finally delivered the bike that everyone wanted to see. This ticks all of the boxes when it comes to cliche bike terms. It's longer, lower, slacker, floats up the climbs, smashes the descents. It's hard to find something that this bike can't do. With a 150 up front and 140 in the rear, this bike settles right into the all mountain category and could comfortably be your only bike. The term "quiver killer" comes to mind. Niner also knocked it out of the park on the component spec. All versions come with a Fox 36 and SDG Tellis dropper post which i'm a fan of. If you have any preconceived notions about Niner as a brand, I would recommend you let this bike change your mind.
