GANOPPER Seat Posts Editorial Review
The GANOPPER 100mm Long Seatpot Shim is an excellent product that helps to adjust the seat post of your bike to fit the size of the bike frame. The shim slides over your seat post and effectively makes it thicker so you can attach trailers snugly and reduce shaking, bouncing, and wear. This product can be used with a dropper post and should work fine with it. If you need to use this as a shim, make sure to grease both the inside and outside of the shim so you can remove the parts for maintenance at a later time, or to keep your bike mechanic happy. The shim comes in a variety of sizes, including 22.2, 25.4, 26.6, 27.2, 28.6, 30, 30.4, 30.9, 31.6, 31.8, 33.9, 34.9, and 36. Overall, this product is efficient and durable.
