Does what it should

I recommend this product
ConsNeeded a second spacer to make it fit my set up
ProsDoes what it should
It does what it is meant for.
One thing to note, however: I was using mine to get a 7-speed SRAM cassette onto an 11-speed Shimano freehub body. For this combo, I needed this spacer plus the spacer that is needed for an 8-speed cassette on an 11-speed freehub body, i.e. I needed two spacers. I don't know if that is that case for all 7-speed cassettes, as (so I have heard) 7-speed cassettes come in varying stack heights.

ProsSimple and effective
Worked just fine, with just a minimal amount of adjustment to make the new setup shift sweetly. Used on a new hub to replace a 7 speed freewheel.

Could you please confirm that this is a 4.5mm spacer and not 4mm as is misrepresented on other companies web sites. Thanks
I have just measured at 4.4mm.

Will this work on a screw type freewheel

Will this fit the screw on type 7 speed shimano freewheel. I have an 8 speed screw on type wheel and a 7 speed freewheel.
Thank you

This is designed for cassette hubs only so would unfortunately not be suitable for your wheel. You should not need a spacer to fit a 7spd freewheel to your wheel though, all that will happen is the chainline spacing will be slightly closer to the wheel than the frame.

Did Not See Groove Mark On Spacer, Will It Fit Shimano Freehub?
18 Dec 2015

This spacer is designed for Shimano freehub bodies, there is no grooves because it sits over the top of the splines on the freehub body.
