The Shimano MF-TZ500-7 Megarange is a highly reliable, entry-level 7-speed multiple freewheel designed for city bikes, entry-level mountain bikes, and commuter hybrids. Featuring Shimano’s signature Megarange 34-tooth bailout gear, this component offers an ultra-wide climbing range that makes tackling steep neighborhood hills effortless.
⚠️ Important Technical Distinction for Buyers: This is a threaded freewheel, not a cassette. It is engineered to thread directly onto traditional threaded rear wheel hubs rather than sliding onto a modern splined freehub body.

Product Highlights:
Megarange Climbing Gear: The massive 34T lowest cog acts as an emergency bailout gear, providing a super low ratio that drastically reduces climbing effort on steep inclines without requiring a triple front crankset setup.
Shimano Index System (SIS) Technology: Engineered with computer-designed Hyperglide-style gate profiles and tooth shapes. This layout ensures crisp, predictable mechanical shifting under load when paired with an SIS-compatible shifter.
Corrosion Resistance: Features a robust, low-maintenance black outer protective coating on the sprocket bodies to prevent rust and wear from daily commuting and wet weather.
