REASON FOR MAKING IT: To be a low cost, but high-quality sprocket. It is the first in a new line of high quality Tree products being produced at affordable prices to riders by designing parts in unique ways that will cost less to manufacture. We chose to use 4130 steel because it is a less expensive material when compared to 7075 aluminum. It also allows the spline drive system to be one solid piece with the sprocket body, which cuts down on the overall cost. Plus, it is made from thinner stock and takes less time to machine.Key Features of the Tree 4130 Spline Drive Sprocket 25T: Spline drive fits 19mm 48 spline spindles Teeth: 25 Spindle Hole Diameter: 19mm/.750 Material: Chromoly Defined Color: Black Color: Black Weight/Dims: .15 lbs. 4.5 x 4.5 x .5 - $29.99
