SJS Customer Service:
Hi,

This freewheel you have left this question on is indeed a screw on option so should be suitable for your needs.

Thanks.
Do You Sell A Hub That Fits This Cassette?
By
28 Jun 2016
I'm trying to fit this cassette but the hub I currently have is too thick (more diameter that the one I have in the cassette). I suppose to have a shimano hub for 8 speed and I intended to use spacers but the problem is that the cassette doesn't even fit.

Thanks!
SJS Customer Service:
Hi,

This is a freewheel rather than a cassette, this is designed for older style hubs where the freewheel screws directly onto the hub rather than a cassette design where is slides into place.

Thanks.

Hi,

This freewheel should be fine for use with that chainset and that chain.

Thanks.
Will This Fit On A Wheel That Currently Has A 6 Speed ?.
By
10 Jul 2015
the existing 6 speed freewheel is a shimano 600 mf 6280
SJS Customer Service:
Hi,

This freewheel screws onto the hub in the same way as your 6spd did but depending on the length of the hub/the spacing in the frame you may not be able to fit a 7spd freewheel in. This 7spd freewheel measures 34cm in length so you may want to check if you have enough room in your frame for this.

Thanks.
