I’ll need the following to get started:
For half packs: leave cages in place & place your bottles in the cages. Side release cages work best as they allow the underside of the pack to be close to the bottles.
- Place your bike in front of a blank background with minimal shadows (garage door, blank wall). Having the non-drive side facing your camera may offer best view of the full triangle.
- Set your phone to the highest resolution.
- Take two photos. #1 standing back 3-4 meters from your bike, positioning the camera level to the center of the pack space. #2 with camera at same height but closer to include only the triangle area where your pack will be. It’s important that your camera is held LEVEL with the CENTER of your frames triangle.
- Note A, B, C & D measurements (metric preferred). Measure along the tubes from inside corner to corner of where the pack will be. For curved tubes, follow the curve with your measuring tape.
- Measure tubes and determine the desired width of your new pack. (Standard is 2” - 2.5” but can be built larger). If top and bottom tubes are different widths, it works best to split the difference. Be sure that your knees won't rub when determining the width. Make sure to account for some bulge once your pack is stuffed.
For frame with rounded corners. These frame are the most difficult as there is no definitive start & stop points to measure from. If you’re corners are rounded, please send me a quick photo of your frame and I’ll let you know if it’s possible to use the following “tape method”. If your frame looks like this, I may need to ask you to make a template and send by mail in order to proceed
Tape method (for rounded corners)
Place pieces of masking or painters tape as shown so your measurements have a start & finish reference point. Your photos should also include the tape if this method applies
For bolt on option:
E) measure distance from head tube to Center of first bolt hole (measure straight line for this, do not follow the curve if there is one)
F) measure distance from toptube to Center of top bolt hole
Full frame pack: depending on the width of your pack and how close it sits to your chain ring, you may want the bottom of your pack to be flat so it’s above your chain. If you have the clearance, the bottom of your pack can be built lIke a triangle to fit your frame. Specify below (#6) which way you’d prefer.
