1.1
Steel is honest
A chromoly tube tells you what it is doing: under the torch, under the file, under you at 60 km/h on a bad descent. It flexes, warns, and forgives. We have never met a spreadsheet that does that.

DWG MC-26 · REV C · SCALE 1:1
HANDBUILT FRAMES · PROVIDENCE, RI · EST. 2011
Every Mistral begins as a full-scale pencil drawing and ends as mitred, brazed chromoly, checked on the alignment plate to a half millimetre, twice. Two builders. Around forty frames a year. No two alike, all of them true.

72.5° HEAD ANGLE
385 REACH, MM
9/6/9 BUTTED CRMO

1.1
A chromoly tube tells you what it is doing: under the torch, under the file, under you at 60 km/h on a bad descent. It flexes, warns, and forgives. We have never met a spreadsheet that does that.
1.2
A stem swap is a patch; geometry is the cure. We move the tubes, not your spine. Reach, stack, trail and front-centre are drawn around your body and your loads before a single mitre is cut.
1.3
Every joint we braze can be un-brazed. A dented top tube is an afternoon, not a funeral. We build objects meant to outlive their paint, their parts, and quite possibly us.
“A frame should be quiet. The road has enough to say.”
§ 02
Three starting drawings. Each one is redrawn around you.

BUILD 01 / FLAGSHIP
All-road randonneur
Low-trail geometry drawn for a handlebar bag and a long day. Triple-butted 9/6/9 chromoly, thin-wall fork blades raked to 65 mm, and clearance for 42 mm tyres with fenders. It disappears under you at hour nine, which is the whole point.
Framesets from $3,400 · complete builds from $7,900
BUILD 02
Road, quick and not twitchy
A road frame with manners: 72.5° head angle, 415 mm stays, and a fork we braze on Tuesdays because Tuesdays are calm. Stiff where you stand, forgiving where you sit.
Framesets from $3,150
BUILD 03
City porteur
Forty pounds of groceries on the front rack and it steers like nothing changed. Oversized down tube, kickstand plate, double top tube on the largest sizes because we like how it looks.
Framesets from $2,850
§ 03
Millimetres unless noted. Custom drawings deviate freely; these are where the pencil starts.

THE WALL / EVERY FRAME HANGS HERE FOR ONE NIGHT BEFORE PAINT
§ 04
The shop is a former die-cutting room on Anvil Street: north light, a concrete floor with forty years of other people’s work in it, and a ventilation fan we argue with every winter. One bench holds the torch, the other holds the files. Frames move between them slowly.
We braze with silver at the lugs and brass at the fillets, and we let joints cool at their own pace, because hurried steel keeps a grudge. Alignment happens on a cast-iron plate older than both of us, and the last hour of every build is spent with a half-round file and the radio off.
Visitors are welcome on Fridays. You will be handed coffee and, if you linger near the vice, possibly emery cloth.

§ 06

FRAMES · TORCH · GEOMETRY
Twenty-one years at the torch, the last fourteen on her own drawings. Mara apprenticed in a Bremen randonneur shop, kept the metric habit, and will defend low-trail geometry at any dinner you make the mistake of inviting her to.

PAINT · FIT · THE DRAWINGS
Trained as an industrial designer, converted by a borrowed 1974 tourer with a bent fork he fixed in a stairwell. Arjun runs the fit jig, mixes every paint colour in-house, and letters the drawing that you sign.
§ 07
01
A call or a visit. Bring your current bike, your complaints about it, and honesty about how you actually ride. We take notes in pencil.
02
A fit session on the jig, then a full-scale frame drawing. You sign the drawing. We build to the drawing. Nothing changes after the signature without another one.
03
A $900 deposit holds your slot. The queue moves at the speed of two people who refuse to hurry a mitre. We email monthly; you may reply or not.
04
Tubes mitred to the half millimetre, pinned, brazed, and left to normalize overnight before alignment. Your frame is checked on the plate twice: hot and cold.
05
Wet paint in the booth next door, decals under clear, threads chased, faces faced. Crated, insured, and tracked, or collected with coffee.
§ 08
Because it can be repaired, repainted, and re-loved for fifty years. Because tubing walls under a torch respond to a builder in a way moulds never will. And because a good steel frame rides like a conversation, not a lecture.
About five months to the torch, three weeks on the bench, four in paint. Call it seven months door to door. We will not compress the queue for money; we have been offered, and it was awkward for everyone.
We can measure it, learn from it, and keep everything you love. We will also quietly fix its front-centre if it has been clipping your toes for a decade. That part is not optional.
Yes: crated framesets to most countries, complete bikes to the EU, UK, Japan and Australia. Duties are yours; the crate is engineered so the courier would have to try very hard.
Send photographs first. Most bent steel can be cold-set, re-mitred or re-tubed; a front triangle replacement costs a fraction of a new frame. Steel forgives. That is the romance and also the engineering.
Six slots. A drawing with your name on it.
