Carbon Suspension Arm Pins, 1 set (8 pieces) Fits YD-2, RD1.0, RD2.0, SD2.0 All carbon rods. φ3.0mm Inner Pins Carbon Rods x 4 φ2.5mm Upper Pins Carbon Rods x 2 φ2.0mm Rear Outer Pins Carbon Rods x 2 How about trying them for the popular trend of weight reduction? Weight comparison: φ3.0mm is approximately 0.4g per piece, compared to about 2g for steel. φ2.5mm is approximately 0.2g per piece, compared to about 1.2g for steel. I could not measure φ2.0mm with my digital scale. Please check the photo of the digital scale for reference. Also, adjustment with sandpaper or similar may be necessary to fit the size. The length is also cut about 1mm longer, so please adjust with sandpaper or similar. These are cut by an individual. Please consider them based on the photos. *We can also accommodate different lengths, so please leave a comment to discuss.
