"CHUNK" is a masterpiece from "CRUMBWORKS"
I wanted more people to enjoy it.
That desire led to the mass-produced "The Chunk"
"The Chunk" faithfully recreates my wishes.
Fat tire clearance and beautiful curves.
A fusion of old and new specs. That's our specialty.
The shape is retro, but somehow modern. Neo Rétro ATB.
The difference from the Japanese version is the welding and tube materials.
The outer diameter of the top tube has been changed to 28.6mm.
Heat-treated tubing has been used to increase rigidity.
High strength TIG welding is used.
And, passed the "ISO City/Trekking standard test"
But "The Chunk" is not a mountain bike.
It's not designed for action riding like downhill or dirt jumping.
Please understand.
26x2.8" / 27.5x2.8" / 700 x 50c
"The Chunk" offers a lot of flexibility with its tire size. It offers a lot of fun.
Commuter bike with a carrier, basket, and fenders.
Touring style with camping gear packed in bags.
Neo-ATB style with 2.8" tires and a dropper.
I hope you'll enjoy it freely and with your own unique ideas.
