\n

All three pitches belong to the 12.70 mm (1\/2 inch) pitch family but carry different inner widths and consequently different roller contact areas. The pitch number encodes both pitch (first two digits: “42” = 4\/8 inch \u00d7 10 = 12.7 mm; “52” = 5\/8 inch \u00d7 10 = 15.875 mm) and width class (last two digits). For bikes currently running a 420, attempting to fit a 428 or 520 requires sprocket replacement \u2014 the sprockets are not interchangeable between inner width families. Confirm your existing chain’s stamped number before ordering any replacement.<\/p>\n<\/div>\n

The 420’s narrower width versus the 428 (6.35 vs 7.85 mm inner) is the most significant physical difference between the two same-pitch options. Both use 12.70 mm pitch \u2014 and that’s the only dimension that matters for sprocket mesh \u2014 but the 420’s narrower roller means it will not seat correctly in a 428 sprocket’s tooth spacing. Always check whether your sprockets are stamped 420 or 428 before ordering, especially on bikes where previous owners may have upgraded the \uc624\ud1a0\ubc14\uc774 \uccb4\uc778<\/strong><\/a> \uc2a4\ud504\ub85c\ud0b7\uc744 \uad50\uccb4\ud558\uc9c0 \uc54a\uace0\ub3c4 \uac00\ub2a5\ud569\ub2c8\ub2e4.<\/p>\n<\/div>\n

The 420 pitch occupies a clear niche. Understanding both what it does well and where its limits are helps ensure you’re choosing the right specification for your actual riding needs, not simply defaulting to a “bigger is better” upgrade that adds weight without benefit.<\/p>\n<\/div>\n
