Finally I’ve got the radial braking lever branded Adelin. For 35$ it’s quite a good deal!
The package has everything you need: breaking radial lever, Oil reservoir, wire for the STOP rear light. It looks good and seems well made. Only the lever regulation looks a bit cheap… like super tender aluminium. It’s kinda big for the Dio and probably I’ll have to shave some plastic from the handlebar plastics.
