These are on sale for a great price on Dan's!
2 piece
Mine are set up LHD with the welded side on the left, but mine came on my Transition so aftermarket they may differ
Really good deal for the money you can't go wrong
They seem decently strong, but I don't do huge drops
A street rider on YouTube rode them for 2 years before they broke
8 or 48 splined
They aren't super light if you are really that worried, but I don't see this as a problem
You may need to remove them completely to remove the sprocket, but greased up this is not a big deal
These are a great deal for the money and are great for beginners and intermediate riders. Im trying to get ahold of some Profiles from a friend, but really i would probably be better off just riding these and saving money honestly.
