They were testing them for few years as far as I know and they did break quickly(the reason why they weren´t selling them for so long) till they started to use that insert.
How do you know long it took vince to break the first verision?Iciar broke the first version in quite short period of time if remember right...There was pic where his fork snapped just where the insert is in the new version.
What bike Adam rides these days Mark?haven´t seen anything since red sky and his bikes are always fancy,so I´m sure everyone would like to see some pics
It will make em easier for sure,I use 18:16 and I wouldn´t go back to 15.But you should also consider your cranks lenght,I have 170mm,with 175 I might use 15t.
