The 3b-DoubleClamp is a One-Piece CNC machined Aluminium clamp.     
An innovative solution that securely locks the
seatpost and frame together.     
Take care
not to over tighten the screws with this clamp. With the 3b-DoubleClamp it’s not necessary! You no longer have to sacrifice your frame to ensure a tight seat.  



In my experience some riders have problems with straight saddle, but not everyone.

For this reason you can choose to buy the 3b double clamp or not.
If you have such problems you will be happy to adjust your
once in a lifetime and forget the saddle, even if you have to tighten 3 bolts.
I have seen some frames broken due to over tight, trying to keep the saddle in position.
This 3B-Double Clamp is for these riders......
