how do you measure the seat post for the rear mount?
Outer Diameter (OD) of the seat post tube. The distance across the outside of the circle made by the tube your seat post goes into. A low cost caliper is the easiest. You can eyeball it with a square (or two squares) and a ruler. Or you can measure the circumference with a piece of non stretchy string (for example) and calculate OD, D = circumference you measured ÷ 3.1416 (pi)

Sorry for the math. It's early here! (there are probably easier methods!)

Baha math.

Just eye it up with a ruler. They all seem to be fairly standard sizes so you can get close and round off to the closest standard size. Worked for me anyway :p

I wish this sale had started a week earlier when I ordered my latest batch of odds and ends. Doh!

Sorry - we always are afraid of that when we have a sale. Yet people always ASK for a sale....so we have a sale.

I can tell you we have been orseholes and elbows this week. Jim has some flu, and it's my turn to ship starting today, so if you get a spare body part in your bag or box please return it..duh.
