Jilles tested Speedpassion speedo and didnt like it. No power, especially after 3minutes.. No joke and I am not biased
. This is a few weeks ago, but now he has signed to speedpassion, he probably has to say something different. Also german top drivers tested it and felt the same. They switched back to the GM witch is most likely the best speedo, only super big, heavy, ugly and hard to program...
But for real.. if your not a Pro.. you cant go wrong I think with the speedpassion.. it does the job.
No hard feelings speedpassion guys, only telling the opinion from the Pro's.
