Description

The Flight Park is Rim Nakamura's signature frame, built for going big. You might not fly as high as Rim, but this is the frame he does it on.

It is 4130 chromoly with a double butted top tube and down tube, a 75° head tube at 115mm, a 71° seat tube at 8.25" and chainstays that adjust from 12.9" to 13.6". The mid bottom bracket sits at 11.5", and a 20.5" weighs 2.0 kg. This one is the 21" in black.

Features

Rim Nakamura signature frame. Built around what Rim rides, in a 21" top tube and finished in black.
Double butted chromoly main tubes. 4130 chromoly butted through the top tube and down tube keeps the weight at 2.0 kg without thinning out the ends.
Chainstays adjust 12.9" to 13.6". Slide the wheel forward for a quicker back end, or run it long when you want a more settled feel on big transitions.
Steep 75° head tube. The front end turns in fast, which helps when you are setting up spins and lining up airs.
Mid bottom bracket at 11.5". The mid shell keeps the bearings tucked inside the frame and the 11.5" height keeps the cranks up out of the way.

Top Tube Length - 21

Frames are sized by top tube length. Start with your height, then let riding style decide where in the range you land.

Rider height	Top tube
147 to 157cm	19.75 to 20.25"
157 to 168cm	20 to 20.5"
168 to 175cm	20.25 to 20.75"
175 to 183cm	20.5 to 21"
183 to 190cm and up	20.75 to 21.5"

The height bands overlap on purpose. If you land in two of them, riding style breaks the tie: longer for flow, trails and transitions, shorter for technical street and park. Plenty of riders, pros included, deliberately ride longer than a chart suggests.

How to measure

Top tube is measured from the centre of the seat tube to the centre of the head tube, so it is not the length of the tube you can see. Measure your current frame that way and compare.

Size up for stability through trails and transitions.
Size down if you want the bike quick and twitchy for spins and grinds.
Top tube is fixed once you buy, but chainstay length, stem length, fork offset and bar position all change how the built bike feels.
