[MASH] AC-4 / Long-awaited release!!

Hello!
Long time no see, it’s Nobu!
Guess what, that time of year is here again!!

Many of you who follow MASH on Instagram have probably already noticed.
Thanks to the kindness of Blue Lug, we are happy to be selling these at Circles again this time.

This release is the MASH AC-4!

The AC series has seen incremental improvements, and this is now Ver. 4.

Release Schedule

Sales will begin in-store on Friday, 10/4.

Online sales will start on the WEB SHOP on Sunday, the 6th at 7:00 PM!

Please note that, as always, the timing for in-store sales and WEB SHOP sales is different!

In-store sales will start on Friday, October 4th.
We would like to prioritize serving those who are able to visit Circles in person.

After that, sales will begin on the WEB SHOP from 7:00 PM on Sunday the 6th.
Please be aware that due to limited stock, there is a possibility that items will not be available for the web store.

Available in 5 Colors

This time we have a 5-color lineup!
Let’s take a look at all of them!

What do you think!
The design is once again by Al Nelson.

The bikes he designs are always novel and stunning. It’s like a bicycle, but it feels like art...

Whether in the city or in nature, a MASH frame looks like a work of art on its own. I’m sure many of you understand this feeling that is hard to put into words...

Neon Algae

Blacklight Purple

Chacoal Silver

Raw Matte

Raw Smoke

Some of you might think the Raw Matte and Raw Smoke colors have been released before, but they are actually slightly different.

Let’s compare them right away.

The one on the left is the current Raw Matte, and the one on the right is the Matte Raw released with the AC-2.
As you can see from the photos, the AC-4 has a slightly darker shade.

Again, the left is the current Raw Smoke, and the right is the Phosphate released with the AC-3. As you can see from the photos, the AC-4 has a slightly darker tone.

Updates this Time

The geometry hasn’t changed since the previous AC-3, but the fork has been improved, and it seems the tire clearance is designed to be wider.

We tried out various tires ourselves, and it looks like a 32C can be installed if you’re using brakes! (Be careful, as tires from manufacturers like Continental that measure wider than their stated size might be tight...)

The bike shown on MASH’s Instagram doesn't have brakes installed, but it is fitted with VITTORIA 34C slick tires.

The ability to fit wider tires means a higher BB height and more ground clearance, making it less likely for your pedals to strike the ground when leaning the bike!

Thanks to that, it’s a setup that can handle everything from darting through the city to off-road fun like tracklocross, and even serious sports riding!

It moves with agility, lets you experience the direct ride of an aluminum frame, and looks great when built up. Great to ride, great to look at.

Only the AC series offers a frame like this.

I’ve already got a complete AC-4 build I assembled on display in the shop. I hope you can use it as a reference for your own build!

Finally, I’ve posted one of my favorite MASH videos, so please give it a watch!

The bike ridden in this video is the CINELLI x MASH Parallax frame, which is the predecessor to the AC series. Doesn't it get you excited to think that this frame is even more upgraded than that one!?

If you feel something after watching this video, please come visit the shop!
Let’s talk fixed gear! Haha
I’ll be waiting for you in the shop.
