The pegs are grippy they don't flex or rattle either, but I feel that Attack performance rearsets feel more solid. To each their own in that regard.
However, a question from another member reminded me of another issue I did forget about. The first shift rod I received with the package was so long that the foot lever was too high or too low after being tightened to the quickshifter. I had to request a replacement rod that was shorter so I could at least dial in the foot lever. After I received the replacement, what I now found was that even though I could use the foot lever, I would hit the kickstand at certain positions while adjusting the rearset (which prevents you from shifting). Fortunately, the position I ended up using also avoids hitting the kickstand, but it required playing around with the thread length and the placement of the nut so it would stay in place. This would have been a dealbreaker for me had I received the opportunity to read reviews beforehand, but Moto-D at least tried their absolute best to make things right for me from their end. I hope they resolved the reported issues and you receive a quality set.
