This is a 20 inch specialized hotrock 21speed vintage, gotta be at least 8-12 years old, has no quick release, but is in good condition for age, rides perfect other than will need a gear service, but has marks on tried to picture them. This bike was built to last as you can tell, and the specialized brand in this era were bomb proof. 40 ono forgot will need a new seat but this was original one so just kept it on, also back tyre is low on tread
