Components V2 Carbon Handlebar
OneUp
The OneUp Components V2 Carbon Handlebar is purpose-built for riders battling hand fatigue, arm pump, and wrist pain on long, rough descents. When the industry adopted the 35mm clamp standard, many handlebars became excessively stiff. OneUp addressed this issue by developing a patented ovalized profile that transitions from the 35mm stem clamp into a flattened shape through the transition zone before returning to standard control dimensions. This design maximizes vertical compliance to absorb impacts while preserving lateral stiffness for sharp, responsive steering. In real-world use, testing outlets consistently praise the V2 Carbon for offering one of the most forgiving rides on the market. It noticeably filters out braking bumps, rough chatter, and square-edged hits without feeling disconnected or mushy when muscling the front end into tight corners. At approximately 235 grams, it hits a very competitive weight for an aggressive trail and enduro-rated carbon bar, providing meaningful weight savings alongside its comfort benefits. The trade-off lies primarily in aesthetics and cockpit organization. The ovalized shaping gives the bar a distinct look that some riders may find unconventional compared to traditional round tubing. Furthermore, the flattened profile limits the real estate available for mounting certain bar-mounted accessories, such as computer mounts, lights, or specific remote levers that clamp close to the stem. For pure descending comfort and fatigue reduction, however, it remains an industry benchmark. **Highlights** - Patented ovalized shaping balances vertical compliance with lateral steering stiffness. - Highly effective at reducing arm pump and wrist fatigue over repetitive chatter. - Competitive weight of around 235 grams suitable for trail through enduro applications. - Tested to rigorous DH standards for strength and impact resistance. - Standard 35mm clamp diameter fits modern mountain bike stems. **Watch-outs** - Ovalized shaping reduces clamp space for lights, GPS mounts, and accessories near the center. - Distinctive flat profile may not appeal to riders preferring a classic round aesthetic.

Components Loam Carbon Handlebar
PNW
The PNW Components Loam Carbon Handlebar targets trail and all-mountain riders seeking an optimal balance of vibration damping, strength, and sensible geometry. PNW recognized the pitfalls of early oversized carbon bars and spent extensive development time tuning the carbon layup. Utilizing premium pre-preg carbon fiber, the bar is engineered with directional compliance in mind, intentionally filtering out high-frequency trail buzz without sacrificing the torsional rigidity needed for aggressive line-holding. On rough descents, the Loam Carbon does an exceptional job absorbing the constant micro-vibrations that cause hand numbness and forearm tightness over the course of a long ride. Reviewers highlight its forgiving feel through rock gardens, noting that it softens harsh feedback without delivering any unwanted flex during hard out-of-the-saddle sprinting or heavy G-out compressions. Weighing in at roughly 233 grams, it sits right in the sweet spot for a durable, gravity-rated composite bar. PNW opts for a slightly relaxed sweep profile (typically 5 degrees upsweep and 8 degrees backsweep) that aligns well with neutral wrist positions, though riders who prefer extreme ergonomic angles might find it relatively standard. At approximately $159, it undercuts several boutique carbon competitors while matching them in damping capability. The main limitation is that it is primarily offered in a 35mm clamp diameter, leaving riders running 31.8mm stems out of luck without replacing their cockpit hardware. **Highlights** - Tuned carbon layup provides noticeable damping of high-frequency trail vibrations. - Lightweight construction around 233 grams suitable for aggressive trail and enduro use. - Tested to stringent downhill safety standards for peace of mind in rough terrain. - Neutral, wrist-friendly geometry accommodates a broad range of cockpit setups. - Strong value proposition among premium carbon handlebars. **Watch-outs** - Limited to modern 35mm clamp setups, requiring a stem swap for 31.8mm users. - Moderate sweep profile may not satisfy riders requiring extreme backsweep ergonomics.
