Default Re: Thing to do / know before getting a Jack Shaft

You will need a cone wrench in order to remove the cone bearings and a special tool to remove the freewheel/cassette. Remove the old axle being careful not to lose the bearings. Wipe off the old grease and apply new grease. put everything back together. Probably the easy way to do it is to take your wheel and new axle to your local bike shop and have them swap it out. Actually, you may want to check with your local bike shop to see if they carry chromoly axles. If they don't have them, then they can tell you what size you will need. A 26 inch wheel normally takes 3/8" diameter and whatever length depending on the freewheel/cassette size. I have a 7 speed so I got the 185mm but I probably could have used a 175mm axle.
