Brompton derailleur wheels

The jockey wheels on the chain tensioner are made of a durable nylon material

Over time these will wear and could help cause the chain to slip when under load

It is common to replace the complete chain tensioner assembly - but it's possible to replace just the jockey wheels and associated components to save some money

This derailleur jockey wheel pack consists of the following items:
Pair of jockey wheels (idlers) for derailleur (2 or 6 speed) Brompton chain tensioners - 10 tooth
Bearings (pair - approx 19mm long with a diameter of 6mm
Fixing nut (approx 30mm long) and bolt (pair)
Washer (pair)
Dust cap (pair)

It allows you to replace just the worn jockey wheels on a Brompton chain tensioner 

Tip: to keep your jockey wheels lasting longer (this applies to all drive chain components) - keep them clean from dirt / too much oil as this will cause them to wear quicker

Tools required:
2.5mm allen key / hex wrench
10mm spanner
small flat head / blade screwdriver

Brompton Q part code: QCTIDLDRSET
Brompton part number: 9023097

Does the job

While a little disappointed to have to replace within the year after average mileage, change and spare part/s were at least not that expensive and Brompton is back to its best again. Thank you Mike and Brilliant Bikes again for great service.

      HiWhilst you recommend it over-piling jockey wheels, presumably some oil is recommended?And if so, what would you recommend in the way of lubrication, and how much?Thanks Answer:
      Sorry - we don't understand your question - please could you elaborate?

      Sorry, bad spelling mistakes. What it should have said is: Whilst you recommend not over-oiling jockey wheels, presumably some oil is recommended? And if so, what would you recommend in the way of lubrication, and how much? Thanks Answer:
      The screw that runs through the washer should be lightly greased - no oil is strictly necessary to help the plastic glide over the metal - though a light oil can help lubricate but could just attract more dirt. Check out the data sheet on the product page
