Fatbar 35
Renthal
The Renthal Fatbar 35 is built for aggressive trail, enduro, and downhill riders who prioritize bombproof reliability, steering precision, and predictable feedback over shaving the final ounce. Renthal has long been a staple in motocross and downhill racing, and that lineage translates directly into this bar. Manufactured from high-grade 7-series aluminum alloy, it delivers exceptional impact resistance that provides peace of mind when casing jumps or laying the bike down in rock gardens, scenarios where some riders remain hesitant to trust carbon fiber. On the trail, the Fatbar 35 is known for its uncompromising directness. The 35mm clamp diameter paired with Renthal's tapered wall profiling results in instant front-wheel tracking, allowing riders to hold technical lines through high-load berms and off-camber roots without vague deflection. The trade-off for this pinpoint control is firmness. While it avoids the harsh, wrist-jarring feel of early-generation 35mm alloy bars, it does not mute high-frequency chatter as effectively as engineered carbon alternatives. Riders sensitive to forearm fatigue on sustained braking bumps will feel the trail more directly. At a verified weight around 311 grams, it carries an expected weight penalty over carbon competitors, but it offsets this with superior crash resilience and a significantly friendlier price tag near $111. The shot-peened finish and hard-anodized surface treatment also resist cable rub, brake lever clamping marks, and general trail wear better than almost anything else on the market. **Highlights** - High-grade 7-series aluminum construction offers exceptional impact and crash resistance. - Oversized 35mm clamp interface provides precise, flex-free steering under heavy loads. - Hard-anodized and shot-peened surface resists abrasion and clamping wear. - Detailed setup grid laser-etched onto the center section aids accurate cockpit adjustments. - Available in multiple rise options to fine-tune rider stack height. **Watch-outs** - Heavier than composite alternatives at roughly 311 grams. - Transmits more high-frequency trail vibration than compliance-tuned carbon bars.

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.
