Thanks to your support, we have been receiving a great response to SKLAR's new production model, the PBJ.
For more details, please be sure to check out the release blog and the first report blog on my PBJ below.
As I mentioned in that blog, another test bike I had been preparing for Circles Tokyo is now ready!
You can test ride the PBJ (Size L) at Circles Tokyo
The one I prepared for Circles Tokyo is in Moss Green, size Large.
It has a gray base, but it's a very nice color with a subtle hint of green. While my own PBJ was built with a high-intensity, jam-packed component list, this one was assembled with a "necessary and sufficient" selection of parts, capturing the PBJ's concept while ensuring it's simply a joy to ride.
Also, this bike is equipped with a dropper post.
If you plan to ride everywhere—flat land, climbs, and descents—the benefits of a dropper post are immeasurable.
Naturally, the seat tube is designed with internal routing for a dropper post, allowing for a clean build.
The main groupset is SRAM GX Eagle, paired with SRAM 900 series hubs.
Personally, I assembled this with the image of an ultimate utility player focused on off-road—one that can handle some trail riding even without a suspension fork, and is ready for bike packing in the summer.
I chose mechanical disc brakes for ease of maintenance, but if you want to focus more on trail riding, choosing hydraulic discs is also a valid option.

A Recap on Sizing
Shortly after we released the first blog, we received a lot of feedback, and Adam quickly informed us that an XS size would be added. Please take a look at the chart for each size again. (*Note: The XS size is also designed for 29" wheels, just like the other sizes.)
The addition of the XS size is great news for us Japanese riders.
Each size is designed with various saddle heights (measured from the center of the BB to the top center of the saddle) in mind. The reference values for saddle height by size are distributed as follows.
We have also listed appropriate heights as reference values.
| Saddle Height | Recommended Height | |
| XS | 620mm–660mm | 154cm–163cm |
| S | 650mm–700mm | 163cm–170cm |
| M | 690mm–750mm | 167cm–178cm |
| L | 730mm–790mm | 178cm–185cm |
| XL | 790mm–830mm | 185cm–198cm |
Frequently Asked Questions about the PBJ
I'd also like to answer a few questions we've received regarding the PBJ.
Is the wheel size 29 / 27.5+ convertible?
The answer is No. The PBJ is designed for 29-inch wheels. This is partly because 27.5+ tires are becoming harder to find in the current market, but Adam designed the PBJ with 29-inch wheels as the premise. (While it's true that 27.5+ is an effective wheel size for shorter riders, that is not the intended design basis.)
It has clearance for tires as wide as 29x2.6", and one reason is that even if you downsize to 27.5+ tires, the difference in volume is minimal, and you wouldn't be able to get 100% of the benefits of the PBJ’s design concept, which is built around 29-inch performance.
Regarding tire size
Basically, it is set up around 29x2.6", but depending on the rim and tire combination, 29x2.8" is also possible.
If you are doing more on-road riding and want more speed, you could choose a size around 29x2.2–2.4". However, in terms of the bike's balance, my personal recommendation is 29x2.4–2.6".
Can drop bars be installed?
Can you? Yes. Would I recommend it? Personally, no.
This bike is strictly designed to be used with riser bars, and especially because the top tube is long, it can be difficult to find a comfortable position if you switch to drop bars, even if you adjust the stem length.
What is included with the frameset?
The seat clamp and front/rear thru-axles are included.
