This is vintage! 1987 Diamondback Accent I rebuilt a while back.
Mavic double wall rims
Shimano Deore derailleurs
Dual trigger shifters (21 speeds)
Kenda 2.125 smooth tread tires.
Recently traded it with a bit of cash for this 2007 KHS Alite 150
Pretty sure you meant Diamondback Ascent, but it looks like a clean example. I almost bought that exact same bike (new) in my first year of college. Decided I couldn't swing the $400, so I settled on a $359 Nishiki Colorado.
In my humble opinion, the Diamondback was the nicer of the two.
Don't call it a gooseneck.
Yeah, typo... What was really cool about it is it still had the sticker on it from the bike shop where it was bought new in California... I live in Indiana.
