The Motoross is Aaron Ross' first new signature frame in almost 5 years. When we sat down with Aaron to discuss the design we asked him to start from scratch. After some debate he came back to us with 3 main requests. The first was to focus on simplifying manufacturing to allow for a more traditional look and a lower retail price. Next on the list was steepening the head tube angle for a more responsive and up-to-date steering feel. For his last request, Aaron asked us to make the lower headset bearing flush with the head tube when a fork with an integrated race is installed. Changing the head tube angle and making the bearing flush was easy. However, simplifying manufacturing while still maintaining the level of strength that Sunday is known for was a significant design challenge. To solve this problem we used custom drawn and butted tubing for both the top tube and down tube. Each tube has been uniquely dimensioned to handle the stresses that the front triangle has to cope with. The down tube also makes use of an eccentric internal butting shape at the head tube, which allows for a much thicker cross-section in the area where an external gusset would normally be. The end result is the exact frame that Aaron was looking for. Simple, reasonably priced, and responsive.
