When a dedicated cycling publication puts a gravel bike through its paces on real trails and fire roads, the result carries weight. 99 Spoke is exactly that, a respected cycling media outlet with deep roots in both road and off-road riding, known for honest, technically grounded reviews that speak directly to serious riders.
Recently, they took our 2023 Polygon Bend R9X out for an extended test, and their findings paint a picture of a gravel bicycle that plays by its own rules.
A Gravel Bike Built for Riders Who Want More
The headline spec on the Bend R9X is hard to argue with. Carbon fiber Novatec G24 Disc wheels, a wheelset that retails for over $1,100 on its own, arrive straight from the factory, paired with a fully wireless SRAM Rival AXS drivetrain. For a gravel bike priced at $2,999, that combination is genuinely unusual in the gravel bicycle market.
But the real story is the geometry. The Bend R9X sits firmly on the aggressive end of the gravel spectrum, with a 70.5-degree head tube angle, long 440mm chainstays, and a short 495mm seat tube that drops the rider’s center of gravity for confident, planted descents.
The result is a gravel bike that feels at home on the kind of terrain most gravel bicycles politely decline, loose fire roads, rough singletrack, and anything with significant elevation change.
99 Spoke’s reviewer, Josch Kirchoff coming from a mountain bike background, found the riding position immediately familiar and confidence-inspiring at speed. For mountain bikers looking to explore gravel riding without abandoning the geometry they trust, the Bend R9X is described as a natural and logical first step.
Generous mounting options across the frame and fork, 16 points in total also make it a strong candidate for bikepacking and loaded touring.
The Dropper Post Conversation: RockShox Reverb AXS
One of the more nuanced points in 99 Spoke’s review centers on the RockShox Reverb XPLR AXS dropper post. The concept is right: a dropper post on a gravel bike makes real sense, especially given the Bend’s mountain-inspired geometry and the kind of terrain it’s designed to handle.
The issue is travel. At 75mm, the post falls short, literally of what the Bend’s low seat tube calls for. Taller riders in particular may find themselves running the post near its minimum insertion limit, leaving saddle height on the table.
It’s a detail that doesn’t undermine the bike’s character, but it’s worth factoring in when configuring a purchase. A longer-travel replacement post would unlock the full potential of the frame’s design intent.
Product Takeaway: A Smart Entry Point Into Aggressive Gravel
The 2023 Bend R9X is not trying to be the fastest or lightest gravel bicycle on the market. It’s trying to be the most capable one at its price point and on that measure, it largely delivers. Carbon wheels, wireless shifting, and trail-ready geometry at under $3,000 is a compelling package for any rider who wants to push beyond the paved paths and groomed gravel routes.
For mountain bikers ready to explore the world of best gravel bikes, the Bend R9X offers a familiar foundation with the range to grow into. Minor adjustments, a longer dropper post, potentially a wider cassette for steep climbing can tailor the bike further.
But as a starting point, it’s one of the more honest and adventurous gravel bikes available at this price.
