Instructions rounded corners

With a few photos and specific measurements of your triangle, I'll be able to create a template and build your pack to size.

For full frame packs with bolt on option:

Remove bottles from cages. If you've got the time, please also remove the cages and partially re-thread the bolts so they are visible in your photos.

For half, wedge & double decker 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 your bottles. If there’s room to drop your cage(s) down further, consider purchasing bottle cage height adapter(s) to maximize pack size.

📷 PHOTOS

Place your bike in front of a blank background with minimal shadows (garage door, blank wall) and standing up straight so your photos are not skewed. Having the non-drive side facing your camera offers best view of the full triangle.
Set your phone to the highest resolution & wipe your lens clean.
Take two photos. #1 standing back 10 - 15 feet from your bike, positioning the camera level to the center of the triangle showing both wheels. #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 and square with your frames triangle so the photos are not skewed.

Example:

📏 📐

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 (if down tube is curved near head tube, it may be best to measure from bottom corner up to centre of lowest bolt to achieve a straight line. Please indicate if your measurement was taken this way)

F) measure distance from top tube to Centre of top bolt hole of seat tube

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.
