MASH Steel Frames 7-21

Enclosed are notes for our 2021 steel frame delivery. This post includes details of the new finishes and the size chart. Each year we make a batch of frames, and since covid, the frames have been selling out in seconds for some sizes, and a day for others. To level the playing field, we are going to host an email raffle in the next two weeks, where you can sign up for a spot to buy a frameset. Check Instagram, Facebook, and here next week for the release date. Shops will receive 3 finishes: Black Rainbow, Matte Phosphate Raw, and Bullitt Green, with a 4th Neon Fade Finish available only at Blue Lug and our raffle at MASH.
We phosphate dip our raw steel frames and finish them with a matte clear. This process slows rust, and is a window into the process of manipulating ancient minerals that make up one of these machines.
We brought back our Bullitt Green finish, this time with a painted rear triangle.
We ED coat all of our painted frames, so steel dropouts won’t rust. It’s small details like this that add up to a thoughtful finished build.
This neon red-purple fade will be available through Blue Lug and MASH exclusively. This Klein inspired long fade has reflective artwork under a gloss clear finish.
The black rainbow finish is quiet in low light, and louder in direct sun.
We cast our own fork crown to offer a classic straight blade lugged fork with a steep rake.
Our steel frames are available in 6 sizes. We label them based on the top tube length measurement center to center. Our frame feels like a classic track bike with nearly matching top and seat tube measurements. Smaller frames will have toe overlap, creating a more aggressive feeling.
This build is shown with 35c dirt tires. The frames are designed to clear most 40c 700c tires, and we’ve seen some fun 650b builds.
Each Steel frame is compatible with front and rear canti or mini v brakes. Each frame includes removable brake studs, seat collar, and top cap assembly, water bottle and brake hole plugs, along with the frame and fork.
