Bid on a 2019 Niner RIP 9 RDO IMBA Custom Mountain Bike

Every year, Niner puts together a handful of custom RIP 9 RDO bikes, with custom paint, and auctions off to raise money for IMBA. For 2019 there is a small, medium, and large bike up for auction on eBay, more detail below.

Without trails a mountain bike is just a bike. Some of us live in places rife with dirt ribbons and we get spoiled. We don’t realize that many places lack any riding at all let alone epic bike-specific playgrounds that extend to the horizon. Perhaps worse other towns are losing trail access due to a variety of threats.

That’s where the International Mountain Bicycling Association (IMBA) comes in. Its mission is to create enhance and protect great places to ride mountain bikes. For more than 30 years this not-for-profit organization has been working on behalf of mountain bikers to make sure we do have great places to ride. To support IMBA’s mission we’re auctioning off four special bikes this month: Three Rip 9 RDO bikes from Niner and a special team-edition Kona Operator DH bike. These bikes are built to go big – very fitting since IMBA has big ambitions to improve trail access for everyone.

We dare you to find a trail that the RIP 9 RDO can’t handle. This custom-painted 29er has 140mm of rear travel on Niner’s CVA Suspension platform and 150mm up front slacked-out on a 66-degree head tube or a 65-degree angle if you switch the geometry chip. These carbon bikes are all built up with SRAM FSA and Ergon parts.
