Sinister Frames
Gruitr
Riding bikes is about fun, not complication right?! The Sinister Progression continues with another design that pedals very well and can be thrown around with ease on your favorite burly trail. The Sinister Gruitr is the bike to have for 2008!
We are rider owned and independent so we can do whatever we want and we want to have FUN on trails. Remember that? 4.5-5.5 inches of single pivot love floating on needle bearings with BTF inspired geometry ensure that you will step it up this year! Climb up and then SHRED, CARVE and RIP down with aplomb.
