Fitment compiled from Sunstar catalogue data for this sprocket series. Changing the tooth count changes your gearing: fewer teeth on the front or more on the rear gives stronger acceleration, the opposite gives a longer top gear. Always replace chain and both sprockets together. Message us with your model and year to confirm before your order is prepared.
Riding in Lebanon
From stop-and-go traffic in Beirut and Jounieh to long mountain descents from Faraya or the Cedars road above Bcharre, Lebanese riding is hard on brakes and drivetrains. Fitting genuine parts at the right interval keeps your bike predictable when it matters.
