Match the hub and derailleur
Check that your rear hub accepts a threaded freewheel. A cassette uses a different hub fitting. Confirm your derailleur’s maximum sprocket capacity, chain length and seven-speed drivetrain compatibility before changing the gearing.
What you receive
One freewheel. The original photograph shows the black SunRace sprocket assembly and its marked 34-tooth largest sprocket.
Fit and adjust
Use the correct fitting tools and adjust the chain and derailleur as required. Ask a cycle mechanic to confirm the fit if you are replacing a different gear range on an existing bicycle.
