Designed specifically for the asymmetric 110 BCD road standard, these oval chainrings deliver smoother power application, improved climbing traction, and exceptional chain retention thanks to Wolf Tooth’s patented Drop-Stop® tooth profile. Mounted in the big-ring position with an optimized inward offset, they create a precise 47.5 mm chainline ideal for 1x road, gravel, and all-road builds.\u003c\/p\u003e\n\n\u003cp\u003eCompatible with popular cranksets—including Dura-Ace 9000, Ultegra 6800, 105 5800, Tiagra 4703\/4700, Sora R3000\/R3030, and Claris R2000\/R2030—these chainrings allow riders to simplify their drivetrain without sacrificing reliability. For Dura-Ace 9100, Ultegra 8000, and 105 R7000 cranks, sizes 40T and larger can be used with a quick, minor modification to the crankarm profile. They are not compatible with the latest Dura-Ace R9200, Ultegra R8100, or 105 R7100 series.\u003c\/p\u003e\n\n\u003cp\u003eThe oval shape reduces dead spots in the pedal stroke, maintaining traction during steep climbs and enhancing overall efficiency. To complete the conversion, Wolf Tooth 6 mm chainring bolts are required, as stock 2x bolts do not seat correctly with a single-ring setup. The chainrings perform best when paired with a clutch-style rear derailleur, and riders using 9-speed drivetrains should run a 10-speed chain for tighter engagement.\u003c\/p\u003e\n\n\u003ch3\u003eWolf Tooth Oval 110 BCD Asymmetric Chainring Specs\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Shimano 110 BCD asymmetric 4-bolt cranks (Dura-Ace 9000, Ultegra 6800, 105 5800, Tiagra 4703\/4700, Sora R3000\/R3030, Claris R2000\/R2030).\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdditional Compatibility:\u003c\/strong\u003e Dura-Ace 9100, Ultegra 8000, and 105 R7000 with simple modification (40T+ only).\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNot Compatible:\u003c\/strong\u003e Shimano R9200, R8100, or R7100 series cranks.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Big-ring position; offset inward for proper 1x chainline.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolts Required:\u003c\/strong\u003e Wolf Tooth 6 mm chainring bolts (stock 2x bolts will not work).\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTooth Profile:\u003c\/strong\u003e Drop-Stop® wide\/narrow for secure retention and mud shedding.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChainline:\u003c\/strong\u003e 47.5 mm.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeights:\u003c\/strong\u003e 38T – 66 g; 40T – 74 g; 42T – 81 g.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 7075-T6 aluminum.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMade in the USA:\u003c\/strong\u003e CNC-machined in Minnesota.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eDesign Benefits\u003c\/h3\u003e\n\u003col\u003e\n  \u003cli\u003e\n\u003cstrong\u003eImproved pedaling efficiency:\u003c\/strong\u003e Oval profile smooths the stroke and enhances traction on climbs.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExceptional chain security:\u003c\/strong\u003e Drop-Stop® design minimizes the risk of chain drops, even in rough conditions.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOptimized for 1x conversions:\u003c\/strong\u003e Proper chainline and bolt fitment ensure a clean, reliable setup.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBroad crank compatibility:\u003c\/strong\u003e Works with many legacy and current Shimano road crank models.\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003ch3\u003eFinal Take\u003c\/h3\u003e\n\u003cp\u003eThese Wolf Tooth oval chainrings offer a refined, efficient upgrade for riders converting to 1x road or gravel setups.
