Ritzel vorne

Front sprockets from Sitta — the small gear with the big lever on your final drive ratio. One tooth here equals roughly two and a half at the rear, which makes it the quickest way to re-gear a bike.

Going one tooth smaller sharpens acceleration everywhere; one larger calms a bike that revs too busily at cruise. Precision-cut steel with the correct spline fit for your model — check the listed fitment, and inspect your chain when you swap, since gearing changes may alter chain length requirements.
