While the 44-16 can be directly achieved down to a 25-9, many riders have chosen to “gear-up” which means higher top speeds and help during roll backs. If you look at two of the most high speed riders out there, Gary Young and Chase Hawk, they are both geared up, sometimes more than one step. One step up from a 25-9 would be 27 or 28-9 which is what Gary uses. Two steps up would be 30 or 31-9 which is what Chase regularly uses.
Some of the 2010 Odyssey sprockets have a new teeth profile design, called Incisors. This will be a running change throughout all the sprockets. The Incisor teeth have a new profile that help engage the chain in a much better fashion. While the teeth seem like a generic instrument, the engagement between the chain and sprocket it’s the most important function. The chain feeding on to the sprocket is improved, and contact with the chainlinks is improved. It’s all the small things added up that create a machine that is greater than the sum of its parts.
The Burlington sprocket is an improved, stiffer, stronger version of its predecessor, that also benefits from the new Incisor teeth profile. In addition to the strength and functional advantages, this new version will be available in various sizes.
