Here is a list of available NCF holder to date. Keep checking back to see what new has been added.
Most posts come it two versions. The SO, a slip on and the LT, attaches with an elastic band. The slip on is perfect for a race only bike. But if your training bike is also your race bike, then the LT is best since it can be removed easily.
If you do not see your seatpost/seatmast listed let us know and we will place it on the list of frame number holders to design.
