The Spank Vibrocore bars got me googling about injecting foam inside the handlebars. Seems like it is well used trick to reduce engine vibrations on motorcycle handlebars, but has anybody done it on their DH bike?
Does it make any difference in reducing arm pump?
I think Spank's theory about arm pump being caused by low amplitude high frequency vibration rather than big hits might hold some truth, because I get roughly similar amount of arm pump on long mellow but fast trails as I get on some rougher trails.
