I am planning to retrofit to the pre 2012 VTS handle/assembly, where the entire grips turns - as opposed to the pita setup they are offering now. Also now is a good time to upgrade my grips.

Not sure if the full length VTS handle is the same diameter as the the other grip/bar side (so I can just order ODI's from the store). Or if I need to find/order a different diameter to run VTS side? Are both sides still 120mm, or will I have to order a 120mm set & a 130mm set? Would not mind being able to run some bar extenders too.
