Before You Decide
Confirm the 170 mm crank length, the square taper JIS spindle interface, and the 9-speed setup before choosing an offer. Also check that the included chain guard matches the configuration you want.
How the Chainring Sizes Affect Gearing
The 48/36/26t figures are the tooth counts on the three front chainrings. At the same rear cog, a smaller front ring generally makes pedaling easier, while a larger ring gives a higher gear. The rear cassette also affects the bike’s overall gear range, so consider its range alongside these chainring sizes.
