Some pix of recent Trek sandblast, powdercoat, rebuild

Thought I'd post some pix of my old Trek beater and daily ride.

First one shows original red and yellow paint...it looked a lot worse around the rear triangle and forks. I had the entire frame sandblasted and powdercoated. The powdercoating did go on a bit thicker than I had hoped, some of the lug definition and cast-in "TREK" logos are not as sharp as before. The powdercoating seems to be really tough, I hope it stands up as well as the Imron.

The bike, an '86 Trek 560 Pro Series I bought new for a bit over $500, has been ridden hard for over twenty years, in all kinds of conditions. It was my rain bike whenever I didn't want to take out the Colnago, Pinarello or De Rosa steel bikes and, in recent years, it had become my beater bike and daily ride around town. The poor old thing was looking a bit tired, the paint was all chipped and scratched. It had no rust, dents/dings or structural damage...just twenty+ years worh of wear. Incredibly, I've never crashed on this bike, even after thousands of miles on the road...it was my lucky bike.

Over the years I'd pretty much replaced every original part on this bike; the only original parts remaining were the Shimano 600 brakes, 600 derailleurs and 6-sp 600 shifters. Everything else had been replaced over time as it wore out. After powdercoating I replaced the old 600 rear derailleur (it was pretty worn out) with a new Ultegra unit, and the worn out 600 shifters (they still worked, but they were pretty loose and didn't index so well) with a set of new 6-sp 105's I'd had for a long time (I got these years ago in the event the original 600 6-sp shifters quit on me). I also had a couple of extra 6-sp Shimano freewheels set aside.

I long ago got rid of all the original cheap SR stuff (stem/bars/seatpost). The stock Matrix rims lasted a good long time, but the original hubs and rims have been replaced over the years with a variety of Mavic rims and other hubs. I'm currently using Campy Super Record 36H hubs with Open Sport rims. Other components I've also upgraded: Dura Ace cranks (177.5mm; replaced the original 170mm Biopace crank/rings), DA aero seatpost, Cinelli (1A stem, bars), Shimano 600 headset, and so on.

This bike had long since ceased being original, or collectable; it just evolved into a good, solid training bike over time. So, I wasn't too concerned about keeping the original paint, decals and such. I'm planning on having the head tube painted a contrasting color, probably white, and adding some decals (when I can find them). That will have to wait...I was in a hurry to put it all back together and take it for a ride.

Nice job- the old bike looks really sharp with the fresh paint and upgraded components. Enjoy the ride- it's obvious that this is a much loved bike. The late Ken Kieffer has a page on his website where he did the same for his old, beloved Schwinn touring bike. I think the page is titled "a new bike for $100". He didn't change the components, just repainted the old, tired looking frame. His point was that the frame fit him like a glove and was a joy to ride, so why replace it?

Very nice job, sop. The old 560's are great bikes, imho, and are undervalued. Straight Reynolds 531 frames as I recall. I hope you get 20+ more years of enjoyment from it. Best wishes.

Nice Trek!

That blue (or very close) was also a stock Trek color on the 460 in '84 or '85 I believe

I think the 560's, 660's, and 760's are great. They have a look (or "ambiance" thank you, Dick Cavet) that scream street machine.

It looks much better than the tired factory paint, nice job. What kind of media was used in the blasting (looks like silica?) Did you do it yourself? Do you have any details about the paint process?

I know little to nothing about sandblasting or powdercoating, so I'm a little hesitant to discuss the process....but a few second-hand observations:

I was referred to this particular sandblaster by the local powdercoater I used, Powder Coating of Gainesville (Florida). They do a lot of industrial powder coating, coating of automotive hot-rod body and engine parts, custom motorcycle stuff and they also powdercoat bike frames for a couple of local bike frame builders.

The blaster uses a fine silica; he's very good at getting into all the little nooks and crevices on a bike frame. I had sandblasted a frame myself many years ago with a friend's blasting equipment. It's a lot more time and trouble than you'd think, and it's also messy; I left a fine, sandy residue on everything within several yards of the operation. And while I did manage to remove most of the paint with the blasting, it took me hours of finish-sanding and filing to get all the hidden areas clean.

This time I was amazed how clean all the areas were, even inside the cable housing guides on the top tube and around the lugs...zero old paint left anywhere. The powdercoater also told me the blasted finish had to have some "tooth" so the coating would adhere well. They advised me not to do any further sanding or finishing that would lessen the tooth left by the blasting. The blasted frame had a sort of satin texture, which can be seen in a couple of the photos. I thought it would look really smooth after blastiing, like new bare steel.

I was also told by the powdercoater that certain colors (powdered pigments) will go on thicker than others. I was trying for a thinner application, so they suggested this particular shade of blue. I had a deeper, cobalt blue in mind, but they told me that shade would have a thicker look.

The frame was ready to go right after it came out of the oven. Unlike paint, that needs to cure for a time before being hard enough to work with, this stuff is as hard as it's going to get right after leaving the powdercoater. I was able to build the frame up that same evening.

As usual, I managed to drop a wrench once or twice while working on the frame, predictably bouncing them off a chainstay, down tube or the BB shell. Normally, with a painted frame, I'd curse and hold my breath, afraid to see how badly I'd chipped the finish...with paint, this would almost certainly damage the finish. With the powdercoating it didn't leave a mark.

If any of you decide to powdercoat, be sure to carefully mask of the top and bottom faces of the head tube, so your headset will seat correctly, and the outside face(s) of the BB shell, if you use old-style cup and loose bearing bottom brackets. Otherwise you'll probably have to have these frame areas faced again before rebuilding. Even with masking, I had to do some fine grinding of a couple of areas around the seat tube post opening and on the head tube faces....the powdercoating is really tough to get off.

Some more pix...
