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.

Immediately yes
Fill Material: Down Alternative, Size: King Size
I’m 50 and peri has been kicking my butt lately, so temperature management of my head (as that is the only thing effected by my hot flashes) has been an ever pressing project that I’ve been managing for the last 3-4 years. Hot sleeping has always been one of my curses, so adding perimenopause to the mix has been my own special hell. But Dyson fans, keeping the bedroom window cracked, and lots of all cotton gauze blankets have been imperative for me in the night. Pillows have always been pillowing, they just get warm and flipping them all night long is just finding the least hot version. I even keep 2 pillow choices on the bed while I sleep, and 2 more an arm’s length away on the chest at the bottom of the bed. Silk pillowcases are great for my hair and skin but they don’t keep cool. THESE PILLOWS, complete with the Beckham cooling pillowcases are chef's kiss. They feel like they’ve been in the fridge. Literally. Now do they stay that way, of course not. But they’re cool enough for me to fall asleep. And if I wake, I use the other side. And if I keep another on standby, I am literally finding the cool side of the pillow all night long. I’m not exaggerating either. These pillows are cool WITH the cooling pillowcases. You can’t use a pillow protector though, even if it’s cotton. It will ruin the effect. And you must use the cooling pillowcases. Do both, and you won’t be disappointed.

Terrible update to a good pillow
Fill Material: Down Alternative, Size: Queen/Standard Size
Purchased this as I was looking to replace tbe previous Beckham hotel pillows I had purchased before. When I saw "newer model available" I ordered it. Wish I had just ordered the same ones as before. First off this was only 1 pillow, not the 2 pack. Since I was only replacing 1 pillow I decided to use it. Huge mistake, my neck has been sore almost everyday. The support of this pillow is terrible, even with trying to added and remove some fill to adjust it. Nothing seems to make a difference. Avoid it and order a different model. Wish I had sent it back for a refund when I got it.

Best Pillow e
Fill Material: Down Alternative, Size: Queen/Standard Size
I’ve been using this pillow for 3 months now. It is, hands down, the BEST pillow I’ve ever had. It’s soft and supportive at the same time. As I noted, I’ve been using it for 3 months and it has maintained its loft unlike some of the other types of pillow I’ve tried. Well worth the price and I highly recommend it.

Good pillows
Size: Queen (Adjustable Foam)
These are nice pillows. I like that you can adjust the firmness by removing some of the stuffing. The stuffing is a combo of shredded memory foam and fill. It holds its shape and support all night yet it is easy to kind of mush it into the shape you like. I sleep on my side and it’s good for that. I got it on a deal and that was a good price - $55 or so for 2 - but I think full price is a little high. There was no odor, and they fluffed up easy with a 20 minute dryer run.

These pillows are amazing. You can add or remove the foam filling..: making it super versatile where you can go from fluffy or flat if you prefer. It’s a great price for 2 pillows. Most comfortable pillow I have bought in forever!!
