Document: what can i say they are pegs, they look great easy to  install and good quality. my son loves them
nice sturdy pegs. Versatile, and slick which helps with grinds a lot. also pretty light, meaning they don't mess with my hop height whatsoever. Overall, no problems, very good, and i would definitely recommend these to anyone else beginner to advanced, who is looking for a new set of pegs.
They are long so you can grind easyier and they make sparks. It's really cool because I go to the skate park in the night so it looks alsome
These pegs don't fit my son's Diamondback Viper BMX bike. The base is so thick that it makes the axle too short on the front wheel, and the welds for the fork are in the way. I ground a bit of the weld away to make them fit the front wheel, but then the axle was too short as well as the locating screw. These pegs represented 15% of the cost of the bike, so I'm quite dissatisfied.
These are good and solid pegs with a large bore. Went on easily on my son's bike. I did have to buy new nuts to mount them to his axle, but that only cost 25 cents and it was because his bike was not set up like the standard axle. They fit great.
These Pegs Are Amazing But Didnt Have Any Instructions , Other Than That , They Are Perfect . They Fit My Kink 2014 Curb .
Smooth, perfect size, good quality, and plenty sturdy. Unscrewed the nuts from the axle, slid these on, and screwed the nuts back on with using a socket extension... Nothing to it!!! If only hang-fives were as easy...
Purchased these to go on a Mongoose Scan R 60. They fit perfectly and my son loves them for doing tricks.
Overall a good investment for a great price. Used daily to grind over almost everything, i recommend this product. Have fun!
My son loves them. He is grinding with them at r local skate park. Fast shoping. Good pegs. Great for my son and his tricks he does at the skate park.
