Just got a 2011 Arlen Ness Vision. Want to put the heel shifter on it. The place I purchased it said all I needed was the additional Chrome Heel Shifter and it looks like there are holes that would mate up to the picture in the parts catalog. The parts catalog shows the part only fitting the 08-10 Cross bikes. The full Heel/Toe shifter only shows it fitting the 08-10 Vision and costs about $70 more. Anybody put just the Heel Shifter on their 2011 Vision?
