Thank you for viewing. This is an LG bumper equipped with a rear skid. You can check the operating range, etc., on YouTube and other platforms based on the photos. Inertia and Slalom Function All carbon fiber, made by Tamiya. Prevents rubber detachment, front and rear. (Rear Skid Roller) Immediately after a curve, the load is tilted, and the rear brake tends to rub against the ground, making the jump posture unstable. After various considerations, I arrived at the skid roller. The skid roller has the effect of reducing the jump distance by idling the tires. Unlike brake sponges, which are pulled by the ground and slow down the speed, the jump posture is also more stable. In addition, the skid roller absorbs the impact from the ground during landing, making the transition to the next section smoother after the jump. Therefore, the phenomenon of the bumper on the side with the skid roller being bounced off the ground is almost zero. However, in some courses, skid rollers may not be necessary. This product can be removed simply by removing the rear nut. Please make your own judgment and install it. Shipped as shown in photo 1. Free shipping. Shipped via anonymous Nekopos. Yuyu Mercari will be +200 because there is no Lawson or post office nearby. Due to the significant price increase of brake stays, I have no choice but to raise the price. *The sellers on Amazon and Yahoo Shopping are resellers. If you buy from them, you will receive boiled broccoli. #HimePapa
