44BMX Seat Post Extenders
Lots of people use these seat post extenders for training, to warm up their legs and to cool down after a race. These are milled out of solid aluminum - comparable to other extenders but at a much more reasonable price. They are light and strong and all of our extenders feature pre-drilled holes so you can mount a water bottle cage for those thirsty work outs.
They come in two sizes: 27.2 and 22.2 for most BMX race frames.
These pair well with the 44BMX seat post clamps (shown in the picture but not included with the extender). The clamps can be found here.
