Freewheel or Cassette?

[JeffD]

I'm almost embarrassed to ask this question as I am afraid the answer will be blatantly obvious to many of you.

I ordered a rear C-lyte 408 and declined also purchasing the optional freewheel thinking I'd use my current one. Then, i got to wondering if mine was actually a freewheel or a cassette? So which is it?


I always like these tight road gears on my city-fied mountain bike. They would be good to have so I can pedal-assist at 20+mph.

Looks like freewheel extractor tool notches in the middle and it sure looks like a freewheel to me.
But it says Dura-Ace? Edit: yep MF-7400 is a freewheel.

Hi

Looks like a screw on but I could be wrong, the late great Sheldon Browns pages are invaluable, check this link it should explain in full the difference, dont worry I sometimes forget as well!! ha ha

Yep, that one is a screw on freewheel. Cassettes have a separate locking ring that screws down onto the smallest sprocket to keep the cassette on the freehub.

Not to hijack the thread but... Has anyone seen options for mounting scooter sprockets onto cassettes? The Downtube folding bikes I'm looking at have cassettes. Looks like I'll have to replace the rear wheel entirely to get one of the thread on freewheel adapters on.

Hi

Most people bolt sprockets directly to them, scooterparts sold freehweeling sprockets a while back that fit on to the hub not sure if they are still doing them though, most people though simply machine them down and bolt them on.

Thanks Pete, knoxie, Mathurin - as it all turned out you were all correct! It indeed was a screw-on freewheel. Its off now and ready for my motor hub when it arrives.

Thanks Guys!
