I have an old Carrera Subway i use for commuting duty, and the drivetrain is shot.
I need a screw on freehub 7 speed and don’t seem to be able to source one.
Also, what is the tool needed to replace it, seem to remember it wasn’t the standard Shimano lockring tool

Freewheels from here (amongst others)

Tool like this from here (amongst others)

Bay of E search for “7 speed screw on freewheel” or variants there of. ~£8 and up…

I had the same proble while lowering the ratios on my sons bike. My LBS (james) had bot the cassette and changed it over for free. They order them from Madison(sp?)

I tried e-bay and got no hits! 😳

Cheers everyone.

Try a motorworld or the similar that sell cheap bikes. Bribe a lad to do it for you. those sort of places are full of screw on freewheels and similar.

Found bits, bought bits.

Freehub/chain/Bottom Bracket/Chainset = £40.

That’ll last me another 18 months i reckon.
