When shopping for a fork for your cruiser, bring your original fork with you so that you can get one with the same steerer length and diameter. Most cruisers are 1" threaded.
However, my aluminum beach cruiser has a 1 1/8" diameter headtube.
Here's my cruiser with MNT bike shocks.....quite a comfortable ride.....has the disc brake system....quite safe as well.....my bike also has the rear caliber brake....in my humble opinion there's barely a discernable difference in the ride between MNT forks and springer forks.....both work well smoothing out a bumpy road.....it all hinges on your preference for aesthetics .....I've also included a snap of my " Black Dog ".....a sprung front on a Ridgedale Cruiser so you can compare....both being cruisers..........in any case....happy building !
A whirly gig !....it's a prop that spins when you ride...supposed to make some kinda noise....I wouldn't know though...it has since been yanked off...too Pee Wee Hermanish for me !
