BikeProUSA Race Case Sizes - Which Size case do I need?
First, measure from the center of the fork dropout to the top of the headset or fork steerer tube when the handlebar and stem are removed.
Next, measure from the bottom of the bottom bracket shell to the top of the seat tube.
On some mountain bikes, the length should be checked as well. If the overall length from front dropout to rear dropout cannot be reduced to 43", a downhill model case should be chosen.
To shorten the length on #3, turn the front fork 180°, if possible.
If any measurement exceeds the maximum for that model, get the larger case.
