New MASH AC-1 Frameset
MASH recently released their first aluminum+carbon frameset since splitting from Cinelli.
Top tube seems a bit long but otherwise looks solid. What you guys think?

A bike company using frame size designations that actually match TT length! Are we finally turning the corner? Hats off to Mash here. It probably costs more than I'd want to pay, but I don't see anything that looks like an idiot designed it -- kind of a rarity.

I'm not particular on how they designate frame sizes, I look at the geometry and can figure it out from there. Long as they include seat tube C-C and not just the arbitrary C-T measurement the bike industry seems to love.
Looking at the geometry some more I think it's actually a good balance. It reminds me of the Parallax but with a slightly longer top tube.

It can take brakes; I guess they just want to sell it without holes for clean lewk and max street cred.
MASH was the first to offer drill-able fork to support a front brake and we have taken it one step further by now offering a drill-able rear brake bridge, so the bike can support front and rear brakes. Perfect for a road trainer or countries requiring two mechanical brakes.

I think it looks pretty good. I've always like the looked of the Mash/Cinelli frames but thought they were a bit pricey and am frankly scared of the ride of aluminum, these look like a good continuation of the line. I like that there's now one version instead of the Parallax/Histogram/Bolt/Vigorelli.
Not quite sure what this means but for what it's worth:

What does "drill-able" mean in this context? I mean anything can be drilled. I assume they mean if you do it right, it will retain the structural integrity to support a brake.

Yeah give me a bike that is drilled, has a nice steel frame and carbon fork, two bottle cage mounts and maybe some hidden fender eyelets and you have a primo machine for the streetz. That bike there might be a fine bike for crashing in Brooklyn with a bunch of other "sw8 fixay ridaz" but as a good practical fixed gear road bike not so much.

They already have a do it all steel frameset. Aluminum/cf is still a popular combo so it only makes sense to offer one. It can run brakes but slightly disappointing it doesn’t have at least one set of water bottle bosses. Not uncommon for them to be missing on aluminum track frames, but hey thought they were supposed to be thinking outside the box!

I know they do but alas it does use a steel fork whereas I want a carbon fork. Aluminum and carbon is OK but without bosses for bottles and maybe racks and not drilled for brakes it is like why try and market it at urban usage just say it is a bike to crash at RHC and all the kiddos will go gaga over it. My old Langster is aluminum and carbon but at least it has two bottle bosses and is drilled for brakes and even has rack mounts (which I haven't used but have considered it)

Most likely a low flange Phil/Mash. Feel like I've seen them with white logos in the past.

Thanks.
I found the non MASH logo'd versions and did a config using the tools at ProWheelBuilder. Even with 20 front and 24 rear they still come out to >1700 grams and >$2700
I still want them, just way less than an hour ago.

People don't buy Phil Wood hubs because they are light but because they look nice and are quite durable with well made bearings in the United Shashes. You really cannot beat a silver or black hub with a nice little red Phil script in the middle.
