Each bike curmudgeon on the web will grumble “metal is actual” when you trot out an outdated body. Metal frames final endlessly, you’re informed, and are simply repaired if something breaks. Effectively, my old steel bike broke on its first mountain bike path, so I took it to customized framebuilder to get brazed again collectively. The method is fascinating.

I’ll say that I had an actual choice in entrance of me when my 1987 Schwinn Cimarron snapped its frame on a trail up in Vermont.

Let’s see these snapped seatstays. These maintain the again of the bike up, and the sharp elements have been certainly pointing quite menacingly at my extra delicate areas. You possibly can see the rusty finger of metal nonetheless caught to the body on the lug, with the seatstays flopping to the aspect. (Seatstays are what join the rearmost level of the bike to its topmost level—two tubes working from the rear dropouts the place the again wheel goes to the joint of the highest tube and seat tube, the place your seatpost suits in.)

Anyway, my choices. I may:

Quit on this explicit body and purchase one other Schwinn Cimarron to swap elements onto.

This was a viable possibility. One other Cimarron of the identical dimension was kicking round in New Jersey, however driving down appeared like a ache, and I may solely assume that no matter issues sprouted up on my Cimarron can be current on one other one, too.

Quit on this bike altogether and get one thing fashionable and never a bit of rubbish. This was the wise possibility. Some corporations nonetheless promote new metal mountain bikes with no suspension, such because the Surly Bridge Club. They’re good-looking and price a couple of grand. I may purchase one and transfer on with my life.

However is the purpose of life to do the straightforward factor? Why not take the tough street, and be taught one thing alongside the way in which? Furthermore, what’s the purpose of getting a metal bike when you’re not going to reap the benefits of it being fixable? After just a few texts and telephone calls, I used to be capable of observe down somebody keen to restore the bike by brazing it again collectively. It’d be enjoyable to see and doc the method, anyway.

That is the choice I took, despite the fact that it meant blurring the road between work and goofing off with an outdated bike.

I additionally wished to do it as a result of it’d be an opportunity to be taught extra concerning the course of that, properly, was the entire purpose why I purchased the bike within the first place.

That’s brazing. Now, there are mainly three ways in which bike frames are put collectively.

1. Lugs: This was once the usual method that bikes are put collectively. Tubes are joined on the joint by becoming into little elaborate sleeves. That is fairly, and stylish. Some folks stay and die by lugged bikes, which may get somewhat fiddly when you get too into it.

2. Welds: That is the present commonplace method that bikes are put collectively. It’s quick, it’s robust, however it’s additionally somewhat abrupt. The tubes simply butt up to one another, and you may see the welds becoming a member of the tubes.

3. Brazing: That is the odd one out. The entrance of my bike is joined like this in a course of known as fillet brazing, the place the tubes are joined with a distinct metallic melted onto them. You possibly can see how my Schwinn Cimarron’s headtube has no ridges of lugs, like you’ll be able to see on the fork, or beads of welds, such as you’d see on a brand new bike:

That fillet brazing is just about why I wished to scoop up this bike. It seems to be attention-grabbing, and it’s how a number of the early customized mountain bikes of the Eighties have been inbuilt little retailers in Northern California. I’m from Northern California! I grew up not removed from these retailers. My crusty outdated Schwinn feels prefer it’s near that historical past.

Additionally, fillet brazing is genuinely beautiful, and virtually a disgrace when it’s lined in paint. Listed here are two fillet brazed stems that Johnny had within the store. The one on the left is polished up, the one on the fitting not but. You possibly can see the fillet brazing clearly: it’s every thing that’s bronze.

It’s expert work, and it leaves these tremendous easy joints, just like the tubes of the bike are all melded collectively in a single, clear kind.

Not less than that’s how I at all times considered it. Brazing, as Johnny Coast defined to me in his store on the opposite aspect of Brooklyn, is rather more widespread in bike building than I believed. Lugged bikes are technically brazed collectively, as are most of the little joints you see on every kind of bikes. Because it seems, the definition of brazing is quite broad.

Brazing is like welding, in that you simply’re becoming a member of two items of metallic collectively. Welding means melting each these items of metallic into one another. You’re heating up, within the base of a metal bike, two items of metal tube so scorching that they soften, and after they cool they quiet down into one stable piece. Brazing is to affix them collectively with out melting them however to soften a second type of metallic round them. Within the case of my bike, which means jointing two items of metal with bronze. You don’t should warmth the metal as much as the purpose the place it melts, simply to the purpose the place the bronze melts round it. When it cools, every thing is glued collectively. Joe at Cobra Frames has clarification of it, and relates it to soldering:

The trick about brazing a motorcycle, as Johnny Coast put it, is that you simply’re not precisely gluing two items of metal along with bronze. The method works on a molecular degree to bond every thing up. Right here’s Johnny helpfully illustrating how the metals be a part of, as represented by wiggling fingers:

Because of this the brazed joints on a motorcycle nonetheless maintain as much as a long time of use despite the fact that there’s really little or no floor space becoming a member of issues up.

The opposite factor about it’s that it is extremely enjoyable to look at.

It took messaging just a few framebuilders till I obtained a constructive reply from Coast. I dropped the bike off and returned per week later to see a few of the precise brazing in motion, the precise forming of the brand new seatstays to interchange what snapped off my body. It will be good to see the.little time-consuming particulars come collectively.

To start out the brazing course of, Johnny first brushed the metallic with one thing known as flux. It is a chemical concoction that “stop[s] contamination of the mum or dad and filler supplies” as famous by Framebuilder Supply. Mainly the flux melts and retains out every thing however the metal and the bronze. It’s what Johnny watches to assist gauge when the metal is at simply the fitting temperature to start out brazing. The blue foamy flux begins to bubble, then turns glassy because it turns into prepared. From there you simply deliver the bronze to the glowing, glassy mess of metal and flux, and the bronze melts into place. It really works by capillary motion; the bronze travels in the direction of the warmth, guiding itself to the joint. “I’m simply asking it,” Johnny says.

The best way he places it, the entire brazing course of is making the surroundings proper for the bronze to soften and set proper. It’s about creating the fitting situations, and the metallic does the remaining.

I consider welding as type of meditative—that you simply want your regular hand, your persistence and precision to set bead. Brazing feels virtually comically constructive. You’re simply making a pleasant, constructive surroundings on your bronze to do its work. Each time Johnny raises his hand away from the glowing tube, a little bit of the bonze rod has merely disappeared, prefer it left for faculty or one thing.

It’d be an identical course of for becoming a member of the seatstays themselves to the body. Brush them with flux, gentle ‘em up with a torch till the metal glows and the flux turns glassy, then let some bronze soften them collectively.

I’ll additionally say that at every level of the method, Johnny was blissful to level out every place the place Schwinn cheaped out through the building of my bike. Every little thing in bike manufacturing, as Johnny defined, is nearly time. Making a motorcycle as shortly and as simply as doable is the way you make cash as a significant bike producer. My Cimarron, as he famous, was filled with little reduce corners.

On my bike, the seatstay’s authentic ends weren’t brazed on however simply smushed into place. Johnny was going to braze on new finish plates for them, which is prettier, smoother, and stronger.

On my bike, the seatstays have been brazed proper onto the body. Johnny filed somewhat groove into both sides of the lugs on my bike’s body to get them to sit down higher. Small particulars, however significant ones that differentiate a high-end bike from a low-end one, a manufacturing bike from a customized one. Coast level out little punched holes and different indicators of cheaper building I may have by no means acknowledged alone.

We additionally obtained to see {that a} failure just like the one I had was positively coming in some unspecified time in the future. At one level Johnny pulled out my outdated seatstays to speak concerning the metallic bridge that spans them. As he wiggled them in his fingers, the bridge snapped clear off, exhibiting that it had gone rusty inside. I might be mendacity if I didn’t worry that, properly, in all probability this complete Cimarron is a rusty pile of rubbish that can fail at each joint doable. However by the point that occurs I’ll be a bit wiser, until it breaks on a path once more and sends me flying right into a tree.

We walked into the yard of his store, previous the Bridgeport and different equipment, previous the customized frames hanging from the rafters, previous the ‘70 Ford Ranchero he simply redid the entrance suspension of, and previous the wood-fired heater on this outdated Bushwick constructing, not removed from the elevated subway. Within the again have been every kind of bikes. He helped start Bike Kill and a tall bike caught out from below a canopy, wanting like what it was: a handful of bikes welded into.a tower, every wheel turning the one beneath it like a set of gears. He pulled up body after body, stating the place every one had been brazed, from the grimiest outdated Raleigh to the swankiest fillet-brazed Landshark, a cult-classic bike additionally in for restore.

I obtained this Cimarron as a result of I believed it could be like touching somewhat little bit of the low-volume, customized magic that bikes like that Landshark had. I suppose I used to be chopping corners to get it, and I’m not stunned to seek out that Schwinn reduce corners of its personal placing it collectively.

However I’m glad I’m getting an opportunity to make one thing attention-grabbing out of it. I’m glad, additionally, that I’ve a greater concept of what “metal is actual” really means.
