Rear sprocket 420 37T D76mm

Rear sprocket 420, 37 teeth, D76mm – a toothed wheel on the rear hub. Together with the front sprocket and the chain it forms the drive: the tooth count decides whether the machine accelerates faster or runs faster in a straight line.

• Marking 420 – it must match the marking on your chain, otherwise the teeth will not fit its pitch
• 37 teeth – the same number is also cast on the sprocket itself: "420 37T"
• Four mounting holes and four lightening holes; painted black
• D76mm is taken from the name – there is no drawing for this product, so we do not confirm which dimension it marks
• Replace all three parts together – on worn teeth a new chain wears out quickly and stretches again
• With the same 420 pitch and 37 teeth, the listing has two more sprockets – D48mm and D54mm; the teeth are the same, only the centre dimension differs
• You will find other sprockets in the "Sprockets" category, and chains with their joining links in the "Chains" category

We write only what we know. Before ordering, copy the marking off your chain's side plate, count the teeth on the old sprocket and measure the bolt circle of the mounting holes and the centre bore – we will check before you order.
