An acquaintance gave me a set of wheels he didn't need. They are 26" off a mountain bike. The rear wheel has a splined cassette hub. The wheel I want to replace with it is an older screw-on 6 speed freewheel. The axle on the cassette hub looks about 1/2 or so longer than the one on the freewheel (It has a quick release). Is there any way to get this upgrade to work? The frame is an old Puch Mistral lugged steel roadie frame.
Thanks in advance for your input on this.
