Pivot Pegz are bear trap style pegs that are allow for rotation forward or backward of center. The intent of the peg rotation is to allow your boot to have flat contact on the peg when leaning slightly backward or forward.
Ringing in somewhere around $150 US these pegs are not cheap. However they seem to be extremely well made and so far I have no issue with them. I weight around 275 Lbs and stand on them while forestry roads and offroad. I think I have put about 15000 miles on mine with little issue.
These are nice and shiny - and probably have about 60% more surface area than the stock pegs being both wider and slightly longer. There is no rubber insert to help with vibration however.
I did find that when leaning forward the peg interfered with the kickstand foot-peg and it would start to lower the kickstand a little bit. As a result I cut my kickstand foot-peg shorter. In more recent models of the Terere you will notice they actually relocate this little kickstand foot-peg.
While having no problem at all with this product - I would not likely buy it again. I don't think that it makes enough of a difference for my riding style to be worth the money. I think these are more than a little 'poser' - but that is just my opinion.
I give them 2 gears based on price, and their interference with the kickstand..
