The best rims on the market are the highest grades of aluminum, welded seams and well designed cross-sections to provide high strength at low weights. One of the lightest rims Odyssey makes is also the strongest. This is accomplished by using 7000 series aluminum. The Seven K-A is the original 7000 series BMX rim weighing in at 453 grams. Instead of simply removing material to make light rims, we improved the material so when we reduced the weight we could be confident that we were making an ultra high strength rim. It is actually slighty wider rim than most other double wall rims at 34 mm wide and 17 mm tall.

The Seven K-A is available as a complete front wheel matched to a Marmoset hub called the M7 Wheel.
