I have a 2009 Voodoo Rada, and was planning to riding it after work today, I guess that won't happen. Riding to work, I felt my seat post was a little low so I wanted to rise it a bit. When I tried loosening the binder bolt, I had to turn myself into some sort of Captain Overtorque and... finally broke the bolt , it was stuck and would not loossen.

I always thought the binder bolt was a bit cheap or not the right size. The widht of the area where it attaches to the bike frame is 22mm, I dont really know the length of the bolt itself has it broke but it must be close.

So I ask, do I need a 22mm or a 19mm would be better (more play to squeeze that seatpost)? How do I know what I need?

Thanks

Dan
