Bar Ends- They give the bars increased rotational mass, which, if heavy enough, could help with barspins. But to be honest, I doubt it, and I use rubber grips which cover up the ends neways.
barends do give the bars a lil push atm i am using plastic odi ones but getting the fit ones and it also depends on the grips u use and how stiff or lose you headset is but how did thid thread become about barends i thought it was about the Kc signature model
They won't spin faster with barends, because they are heavier and will require more force to move. But they will spin longer because it has more mass, so it has more inertia.
Haha, wish I could say the same thing. I lost two teeth because of them.
I don't know. Perhaps mine were just too light to notice. But My metal bars ends never made any difference in the way the bars spun. Give me a well tuned headset and I can barspin for days. And I catch singles in like a split second so I never noticed any weight momentum.
