This place has them at a good price . Dont know if they are Triumph or Rivco and im too lazy to look so ill leave that 2 you http://www.allthingstriumph.com/
I have the Triumph bars and Triumph hwy pegs and what Ricochet said about the Quality is spot on, I did not get the adjustable mounts as I did not need them, if you are less that 6 ft ish you may need them and they will give you more postion options but add extra width overall
This is very true. I am 5'11, and I have short legs and long arms.. the adjustable pegs were definitely necessary, my legs would never reach the bars with out the adjustable mounts.
