Wolf Tooth Shimano 110 BCD 40t Chainring – Elliptical Drop-Stop

Optimized Chainring Performance for Shimano Road Cranksets

Engineered exclusively for 4-arm 110 Asymmetric BCD Shimano road cranks, this chainring transforms your pedaling efficiency with intelligent oval engineering. Its 10% ovality and 112-degree post-top-dead-center timing deliver the traction boost of traditional oval rings while eliminating common drawbacks like pedal bob or inconsistent cadence. Feel the difference: reduced strain during weak pedal positions and amplified power where you’re strongest—like gaining two extra teeth precisely when you need them.

Key Advantages for Gravel & Trail Riders:
✓ Unmatched Chain Security: Featuring Wolf Tooth’s Drop-Stop asymmetric tooth profile—optimized for muddy singletrack or bumpy gravel roads—to prevent drops and extend drivetrain life.
✓ Broad Drivetrain Compatibility: Perfectly suited for 1×9, 1×10, 1×11, and 1×12 setups. Works flawlessly with 10-/11-/12-speed chains (Excludes Shimano 12-speed; use Wolf Tooth’s dedicated solution).
✓ Pro Tip: Pair 9-speed drivetrains with a 10-speed chain for enhanced grip.
✓ Built to Endure: Machined from aerospace-grade 7075-T6 aluminum, resisting wear season after season.

Maximize Your Setup:
For peak performance on technical terrain, combine with a clutch-style rear derailleur. This duo ensures silent, reliable shifting whether you’re climbing steep grades or sprinting through loose gravel.
