Before going further, please be aware these items have all sat in a warehouse for over 10 years, and were sent to be destroyed by the manufacturer as they are prototypes OR pre production samples and as such the manufacturer did not want them to be sold in case of any kind of unexpected catastrophic failure.
Obviously there is no longer any manufacturer, or other, warranty on these items.
Due to this and the age of the items, they are sold on the basis of making NOS builds for collector's display bikes rather than hammering round the local skatepark or jump spot.
If you decide to use these parts you are solely responsible for the consequences.
