The classic, resurrected! Originally designed for the Ron's Bikes/Crust Alumalith, this portage-style pack lends just enough room for the essential sundries while staying out of the way of your whirling knees. You can now (re)live the golden era when moms and dads everywhere stretched out over loooooong stems while wearing smooth pistachio-shell shaped chunks of foam on their noggins. If you have an A L U M A L I T H , here's how the sizing breaks down:
Small Alumalith 16"
86º
Medium Alumalith 18"
81º
Large Alumalith 20"
77.5º
X-Large Alumalith 22"
74.5º
Please note these are not the seat tube angle itself but the angle that forms from the sloping top tube to the seat angle.
If you don't have an A L U M A L I T H , determine your fit by downloading this PDF - also attached in these product photos! You can print it out and hold it up to your bike, or put that high school protractor to use for measuring your top tube/seat tube angle, and then make your selection accordingly!
You can also use this .PNG image and overlay it on a flat, straight, drive-side photo of your bike.
