CrumbWorks out of Japan developed a masterpiece of beautifully hand brazed steel in the form of "CHUNK", sweepy lines, a mix of modern and classic standards. But building frames one at a time in Japan is slow and expensive, so frames were landing at north of 3k AUD ex shipping. 

They came up with an offshoot brand to offer the same frame design but produced in batches out of Taiwan rather than made singly in Japan and so now we have the "The Chunk", same frame design but at a more affordable price.

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"

 

At Omafiets we are thrilled to offer "The Chunk", having started the shop importing upright step through dutch bikes many years ago, we have a real deep love for the combination of a step through frame and swept back bars. Some of our favorite bikes from those early shipments were the Koga-Miyata frames, a collaboration between the Dutch and Japanese that was the highpoint of frame design for decades. These Chunk Frames seem a very worth spiritual successor, but updates for modern times, with disc brakes, big tyre clearance but retaining a beautiful silhouette and simplicity.

 

"The Chunk" is a thing of beauty 

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.

 

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.

Contact us via email if you would like a custom build, 

Frame listing is for frame and fork inc thru axles, does not include headset or seatpost collar. We are happy to bundle and install things like headset and bottom bracket. 

The raw clear coat has a "phosphate treatment" under the clear coat.
It should have a degree of rust-resistance, but significantly less than a traditionally painted or powdercoated frame, please wipe it if it gets wet in the rain.
Rust and patina will develop with time and thats an inherent part of a clearcoated frame. 
Applying a water-repellent wax would also be a good idea.
Rust will occur if the clear coat gets scratched.

Bed pillow
The best pillow for people who have a hard time choosing a pillow. Pricey but worth it. Love the way I can conform it to my liking.

Packaging for shipping = terrible. Pillow = 10 stars
The pillow is great; the shipping/packaging not so much. Normally Amazon warns me if an item is being shipped in manufactures packaging and gives me an option to choose to have it boxed in Amazon packaging; I was not given that warning or option for this item. I am honestly confused why anyone would think shipping a pillow in just its vinyl store packaging “dust” cover would be a good idea. The vinyl cover arrived fully damaged. Cuts from what look like a box cutter, the handle 1/2 torn off, the zipper was 1/2 unzipped… Thankfully the pillow was not damaged or this review would be much different; but honestly who ships a pillow of any price point in a 10mil vinyl dust cover? About the pillow. My young adult child has been using a Bedgear pillow for about 9 years…the same pillow actually. It has stayed in a waterproof pillow cover inside a pillowcase that gets washed weekly, and the pillow has held up great. Recently I noticed the pillow was being used without the 2 covers and had gotten something spilled on it. Since the pillow is spot clean only and the inner foam is not submersible in water I decided it was time for a new pillow. Their original model was the original Summit but since they toss and turn and then end up on their stomach we decided to try the Multi position this time. They have slept on the pillow for 3 nights now and seem extremely happy.

Best one so far
Still on the never ending quest for the perfect pillow. Must say that for the price this one can't be beat. Not willing to invest a small fortune on a pillow and this one is extremely reasonable
