Seatpost Shims, 3.7mm Shim, 27.2mm Seatpost to 30.9mm
The Seatpost Shim is what you need when your seatpost is a little too small-diameter to fit tightly into your frame. It’s made of light, durable aluminum and has a lip on the top so it won’t slide down inside the frame during installation.
The BBB TopPost is ideal for mountain bikes. It is made from super strong and lightweight 6061 T6 aluminium to bring riders to the top of the hill in comfort. The TopPost has a low profile, plus a dual bolt adjustable clamp which makes it simple to fine-tune the angle of the saddle. An ideal seat post for every cyclist with an eye for detail.
