Rear sprocket JT JTR1877.47 47T 525

JT Sprockets rear chain sprocket JTR1877.47 made of steel gearing — a British manufacturer with a tradition dating back to 1946. JT rear sprockets are CNC machined with precise tooth geometry for smooth engagement with DID, RK, JT and other chains. Changing the number of teeth on the rear sprocket affects the bike's character: more teeth = higher torque (better acceleration, lower max speed), fewer teeth = higher max speed (suitable for track and highway riding). Delivery time 7–14 days. SKU: JTR1877.47.
