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.

Works Great but the price is rising!
Anua Azelaic Acid is a very good serum. Both my daughter and I use it regularly. My daughter has severe rosacea, and this has helped calm her skin significantly her redness is almost gone. For me, it has also made a noticeable difference by reducing redness and giving my skin a healthy glow. We both use it at night, and it’s definitely very soothing and calming. The formula is gentle, lightweight, and works really well for sensitive skin without causing irritation. However, the only downside is the price, it seems to have increased quite a bit recently, which is concerning. I bought a couple during Amazon Prime Day, which worked out really well. For a relatively simple azelaic acid serum, the price increase feels a bit steep. If the price continues to rise, I may need to look for a more budget-friendly alternative. Otherwise, it’s a really great serum that delivers great results.

DERM APPROVED!
I am obsessed with this product!! This feels very luxurious on my skin and does not pill like other products I have had in the past. I have noticed a significant improvement in the background redness in my skin. As someone who works in derm and values good ingredients and products that actually work... I can confidently say that this is the best OTC azelaic acid product I have tried out. It sits very nicely under my moisturizer and does not dehydrate my skin like other azelaic acid products have done in the past. HIGHLY RECOMMEND

A Game Changer for Sensitive Skin
I use this serum every single day, and it has become one of the most important products in my skincare routine. I have very sensitive skin and cannot tolerate stronger active ingredients such as retinol or high-strength acids, so finding something effective but gentle has been incredibly important. This serum has helped calm redness, reduce inflammation, and noticeably improve my skin’s overall appearance and comfort. After dealing with a prolonged inflammatory skin condition, this product made a significant difference and helped restore my skin barrier. The formula feels soothing, hydrating, and non-irritating. If you have sensitive or reactive skin and are looking for a gentle product to help with redness and uneven texture, I highly recommend giving this serum a try. Photos attached: The green bottle is the product and the second photo includes my favorite additions.

Perfect for Acne-Prone Skin!
This serum has honestly been a great addition to my routine for redness and post-acne marks. The texture is lightweight, hydrating, and doesn’t feel sticky or heavy on my oily/acne-prone skin. I have sensitive skin with a focus on barrier protection, and this didn’t irritate my skin at all. It layers beautifully with the rest of my skincare and leaves my skin looking calmer and smoother over time. AND, it doesn’t have a smell!! Definitely one of my favorite azelaic acid serums I’ve tried.

Great product with unexpected results and skincare benefits
Size: 25 Count (Pack of 1)
I have been reading about Micellar water products for a couple of years, and finally purchased these wipes to try. I am currently working very long hours and the selling point for these wipes was that they weren't soap-based, and didn't require a toner after using. I keep them on my night stand and take my makeup off with them prior to going to bed. (I do not use them for removing mascara - I use another product for that.) The biggest point I want to share is that I have been using these wipes exclusively for makeup removal for a little more than two weeks. I have had a stubborn blackhead on my nose for a good 20 years that wouldn't budge, no matter how often I used exfoliating products, and I've invested a lot of money in high end exfoliators in an attempt to make that spot go away. It has grown larger over the years, and was a skincare peeve of mine. I noticed a couple of days ago that that blackhead is beginning to break down and get smaller. I thought at first that I was imagining it, but that blackhead is honestly a good two-thirds gone. This is just from using these wipes! I would never have predicted that something this simple and quite soft and insubstantial as a disposable face wipe would have such effective results for blackhead breakdown, but they're doing the trick. I have noticed smaller blackheads on my chin area are also melting away. I predict that in another few weeks of use, my skin is going to be as close to blackhead-free as it is humanly possible to achieve. (For the record, I don't have a lot of blackheads - just a handful that have taken up residence over the years and refused to budge, getting larger with age.) These are safe for my sensitive skin, and have exfoliating benefits that I wouldn't ever have expected or predicted. Full disclosure: I do spend a good 3-5 minutes using a single wipe on my face, neck, and décolletage, scrubbing with the nubby side (there is a nubby, exfoliating side, and smooth side to each wipe) and using the whole cloth in sections until I have used it all. Finally, I also use it on the tops of my hands. I definitely get my money's worth out of each wipe! I wholeheartedly encourage people to try this product. I now have it on Auto-Ship status, as I don't want to ever be without these wipes in my skincare arsenal.
