Whether you're restoring a classic build, upgrading an older mountain bike, or dialing in a plus-size Surly setup, this chainring delivers the benefits of Wolf Tooth’s patented Drop-Stop® profile in a format that keeps older standards alive and performing at their best.\u003c\/p\u003e\n\n\u003cp\u003eDrop-Stop technology uses alternating wide and narrow teeth to maximize contact on the drive side while clearing mud and debris on the return, resulting in smoother running, improved chain security, and longer component life. Designed with four threaded holes and one through-bolt hole, the chainring offers direct compatibility with Surly OD cranks. It also fits any 94 BCD 5-bolt crankset, though some vintage models may require minor modification.\u003c\/p\u003e\n\n\u003cp\u003eFor riders running Surly OD cranks on fat or plus-size bikes—such as the Instigator or Krampus—stock spacers and longer 16 mm bolts (available from Problem Solvers) are required for correct positioning. The chainring provides an excellent chainline on most Boost setups and is compatible with 9–12 speed drivetrains. Riders using 9-speed systems should pair it with a 10-speed chain for tighter engagement and better retention.\u003c\/p\u003e\n\n\u003ch3\u003eWolf Tooth 94 mm BCD Chainring Specs\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Fits 94 BCD 5-bolt cranksets; Surly OD compatible; some vintage crankarms may require slight modification.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTooth Profile:\u003c\/strong\u003e Drop-Stop® wide\/narrow design for secure retention and efficient mud shedding.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Four threaded holes + one through-bolt hole; uses stock 10 mm bolt for hidden arm.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSurly OD Setup:\u003c\/strong\u003e Requires stock spacers (QBP CR8609) and 16 mm bolts for plus-size applications.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrivetrain Compatibility:\u003c\/strong\u003e Works with 9–12 speed; use a 10-speed chain for 9-speed drivetrains.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChainline:\u003c\/strong\u003e Designed to offer an optimal chainline on most Boost bikes.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeights:\u003c\/strong\u003e 28T – 37 g; 30T – 48 g; 32T – 57 g.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e CNC-machined 7075-T6 aluminum.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMade in the USA:\u003c\/strong\u003e Manufactured 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\u003eModern performance for classic cranks:\u003c\/strong\u003e Updates vintage and Surly OD 5-bolt systems with top-tier chain retention.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReliable 1x setup:\u003c\/strong\u003e Wide\/narrow teeth reduce chain drops in rough or muddy conditions.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlexible compatibility:\u003c\/strong\u003e Works across multiple drivetrain speeds and bike formats.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDurable construction:\u003c\/strong\u003e High-strength alloy offers long service life on demanding terrain.\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003ch3\u003eFinal Take\u003c\/h3\u003e\n\u003cp\u003eThis 94 mm BCD chainring is the ideal upgrade for riders wanting to modernize older 5-bolt cranksets or optimize Surly OD builds.
