Battersea
Turbocharged
The Max tire was released over here by B'stone in late april- early may 2011, battersea.
They also sell a G850, G851, G853 and a few others with different G designations, all of which are made for specific bikes.
I bought mine over late last summer from DennisKirk.com for $156 shipped. Their price now is about 10% higher than the price I paid.
Interesting! If the Max has been available in the USA since May last year I cant understand the delay in bringing it in to Europe by now.
$156+10% - $172, thats £110 at todays rate.
