If not what alternative freewheels do you have that will suit
Hi there,

As long as the hub has the correct threading this should work.

Will This Cassette Be Compatible With A Shimano Arabesque Friction Shift Rear Derailleur?

I currently run a 14-24 cassette on my vintage road bike but would like this extra large cog for some tricky hills in my area.

You rear derailleur will require some adjustments but it should be compatible with this freewheel.

Will This Freewheel Work With A Huret 6 Speed Rear Derailleur

My current freewheel is an 13 to 23 gear range.

Although the spacing between the gears should be the same we unfortunately have no way of knowing how well your rear derailleur will cope with the extra large 34T cog. It hopefully should be okay, but will definitely need adjusting to suit this.
