ProsBrand, quality and price
It works like it’s supposed to, it’s shimano so what would you expect!
Top quality and good price, if you need a new freewheel you won’t go far wrong. Highly recommended.

Hi there,

Unfortunately this is a one piece item so the ratios can not be changed.

Thanks

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!
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, Will This Fit With The Fc M131 And The Hg40 Chain?

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

the existing 6 speed freewheel is a shimano 600 mf 6280
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.
