Rear sprocket 428 37T D48 mm

Rear sprocket 428, 37 teeth, D 48 mm – a toothed wheel on the rear hub. Together with the front sprocket and the chain it forms the drive: the number of teeth decides whether the bike accelerates faster or runs faster on the straight.

• Marking 428 – it must match the marking of your chain, otherwise the teeth will not match its pitch
• 37 teeth – that many are counted on the sprocket itself
• The number with the letter D in the name is 48 mm. In drawings it does not always mark the same thing: most often the centre bore, sometimes the bolt circle, so before ordering measure both dimensions on your sprocket
• The same category has an identical 37-tooth sprocket but with the 420 marking – the markings are not interchangeable
• Change all three parts together – on worn teeth a new chain wears out quickly and stretches again
• You will find other sprockets in the same category, and chains and joining links in the "Chains" category

To be straight with you: before ordering, copy the marking off your chain's side plate, count the teeth on the old sprocket and measure the bolt circle and the centre bore – we will check it before you order.
