Whether you're tackling technical descents or long endurance rides, Renthal delivers the control that keeps you confident and fatigue-free.

Why Renthal Stands Out in Handlebars

Renthal has built a legendary reputation since 1987 for pioneering fatbar technology, starting with their oversized 1-1/8" tubing that revolutionized strength-to-weight ratios. Their handlebars absorb brutal impacts while maintaining precise steering feedback, thanks to proprietary 7075-T6 aluminum alloy and Fatbar Flex technology for vibration damping. Riders choose Renthal for bars that survive crashes, reduce hand numbness, and enhance overall bike handling—ideal for serious cyclists in the cycling world.

Key Features to Consider When Buying Renthal Handlebars

Selecting the right Renthal handlebar boils down to your riding style, bike setup, and clamp diameter. Here's what matters:

  • Clamp Diameter: Options like 31.8mm or modern 35mm ensure compatibility with top-tier stems. Wider clamps boost rigidity for high-speed stability.
  • Width and Rise: 800mm widths suit aggressive MTB setups, while 30mm rises promote upright postures for control on steep climbs.
  • Material and Finish: Anodized black finishes resist corrosion, and the Fatbar's oval tubing profile cuts vibrations by up to 50% compared to standard bars.
  • Weight: Ultra-light designs around 300g keep your front end responsive without sacrificing bombproof durability.

These features make Renthal bars a step above entry-level options, especially in demanding parts & components.

Comparing Top Renthal Models in This Category

Our selection spotlights two standout Fatbar variants to help you decide:

The 609-01-BK Fatbar Black 1-1/8" Aluminum Handlebar is a classic for riders loyal to the original oversized standard. With its 1-1/8" (28.6mm) clamp, it's tailored for legacy setups or DH bikes needing maximum flex absorption. Its centered rise and swept backs promote natural wrist positions, making it forgiving on all-day epics.

In contrast, the Fatbar MTB Handlebar (35mm Diameter, 800mm Width, 30mm Rise - M158-01-BK) represents Renthal's evolution for enduro and trail bikes. The 35mm clamp pairs with contemporary oversize stems for laser-sharp handling, while the 800mm width and 30mm rise optimize leverage on chunky terrain. Choose this if you're modernizing your rig for better power transfer and reduced arm pump.

Both excel in crash resistance, but the M158 edges out for wider modern bikes. If you're comparing alternatives, check Pro Taper handlebars for similar vibes or SPANK handlebars for budget-conscious carbon options.

Common Use Cases for Renthal Handlebars

Renthal shines across disciplines:

  • Mountain Biking: Fatbar damping tames chatter on rocky descents within handlebars, headsets & stems.
  • Dual-Sport Transitions: Seamless from pedals to throttle with enduring strength.
  • Enduro Racing: Wide bars and rises for bombing berms and climbing tech sections.

Backed by Renthal's motorsport heritage, these bars integrate perfectly into full handlebars builds.
