Started work on this 1985 Pinarello Montello last year. Finally took it to the Bike Exchange for sale this week.

I’ve been working on a vintage (supposedly Italian) track frame, finally found a good compatible BB, the first cheap one had a wrong cup diameter by 0,5mm on the left side.
Finally gonna complete this build and ride it!

It looks like a completely different bike. I really like ridges on the lugs on the bottom bracket shell. What did you use to clean it down to chrome so nicely?

Looks like I might be able to just put this freewheel away as a backup. Got a MF- 6208 today. Unfortunately 13-21, not 13-24 I wanted, but might be just alright and start using the front derailleur and 42T chainring more. It always feels good to bring something back to life though, even something as ugly as these newer Shimano freewheels.

Yeah, that design is really weird. What's wrong with all sprockets being one colour? I don't know what Shimano thought at the drawing board stage. Got two casettes with the same kind of thing, completely unnecessary. All works well enough, but design is a bit ghastly.

And you are both being kind, these are fugly to the nth degree IMO.
They scream cheap, budget which they are but seem to work and last just fine despite that, crappy freewheels will advertise themselves by azzploding.

Over the past few days, I've been rebuilding bikes that have been cluttering my back porch. Need the shade back before hell summer hits.
This one is a 1991ish Trek 750 hybrid. Looked like heck when I got it, but it cleaned up nicely. Full Suntour XCE, except it came to me with a set of thoroughly trashed Grip-Shifts. The cleanup & rebuild went fine until selecting replacement shifters - the Accushift cassette would not play well with the Rapidfire or GripShifts I tried on it, and I had to break into my Emergency Strategic Component Reserve and commit a set of XC Pro thumbies to it in order to get decent shifting.
After all that, I've decided to keep it as a spare bike, with the prior Spare Bike donated to Recycle Your Bicycle to make a foster kid happy.

Next up is a pair of his 'n hers 1994ish Nishiki Manitobas (Manitobae?). These were nearly pristine cosmetically but had seriously gummed-up shifters. After many passes in the ol' ultrasonic, the shifters click freely again (and should stay that way), and the bikes will eventually end up donated to either RYB or RS.

If you look carefully those ridges are the Pinarello logo. As for stripping paint I used paint stripper bought at Home depot. One trick I use to make it work better is to paint on the stripper then cover the tubes tightly with Aluminum foil. This keeps the stripper from drying out and makes it work much better at softening the paint. I then use a disposable retractable razor blade knife they sell for about a dollar to scrape off the paint.

Thanks for the tips on paint stripping from chrome. The frame I'm working on right now has chrome underneath the chipped paint on the chainstays. The paint is most likely original, but I was thinking about giving it chrome socks instead of touching these sections up. I guess we'll see if I manage to get some paint for touchups mixed up.
I used crafts knife blades for the last paint stripping I did and it did work very well indeed. I guess if I'm carefull with the chrome, it should be fine. And, still have some paint stripper left, so thanks for the advice about wrapping it up. Might go for cling film when I get to that stage.

They did go to town with the design of the bottom bracket shell then. Nice touch

While waiting for the rest of the parts for a wheelbuild for the 1965 Gazelle A I overhauled the Sturmey Archer GH6 dynohub.
While it wasn't feeling all that bad, it has definitely improved in both looks and feel now. The bearings were not pitted and looked like new once cleaned so I just lubricated everything and put it back together.
Though I did manage to snap one of the tiny screws in half while tightening them.
No clue on whether it even delivers power anymore, if a previous owner disassembled the magnet it will have lost its magnetism and be useless. Still feels notchy so I think we're fine.
I should have 1-2 pairs of the brass hooks used to connect the wires but I will have to dig a bit in my parts boxes in the shed.
The rest of the GH6 hubs I have: 28, 32 and 36H
I'll probably cannibalize the screw from the 28H one.

Someone in marketing must have thought that all that billboard space on the sprocket should be used to advertise the added low-gear capability. Without the "Shimano" shout-out, you'd have had to look closely to notice the then-unique big sprocket. With it, there's no mistaking it for a conventional, comparatively close-ratio range.
Mixed feelings about the look myself. Still---kudos to Shimano for having come up with the mega-range idea.

My guess at the time of release was that an engineer figured that their derailleurs and shifters would work well with a big jump to the largest sprocket, enabling a double-chainwheel bike to approach the low range of a bike with a triple. It was an unorthodox idea for a stock cluster at the time and was arguably an ancestor of the now-fashionable 1X setups.

Visually, I would definitely prefer just one colour, silver or black. But I'm not overly bothered At the moment I'm using a pretty standard Tourney 7sp casette, which also has black biggest 28t sprocket. So not exactly a Megarange one. Also, I've just got MF-6208 for the wheel I'm going to use at the back when I switch the wheel to one that takes freewheels. No esthetic problems with that one
Speaking of freewheels. I was soaking one in penetrating oil recently (well, soaking the thread on the Superbe hub it was sitting on) for quite a while and today decided to try removing it again. It came off beautifully, like it was never stuck, so I'm very pleased with that. I'm a bit less pleased to see that half of the spokes underneath it are deformed (and one is gone, but I knew about it before). So obviously, these will have to be replaced with the immediate plan to take the wheel apart, measure the spokes and see if I have the correct lenght ones to replace them. Luckily I didn't order spokes for another wheel I'm going to be building, so worst case scenario I can just add some more to the order. The new tyres are on the way already and I went with Panaracer Race C Evo 4, since it's a Japanese made bike (inner tubes are going to be Michelin AirComp though for now, Panaracer's R'Air seem to have dissapeared from the UK shops).
The hub is beautiful. In mechanical terms, at least. It looks like it definitely needs no overhaul, spins just as smooth as the front one I've built up a wheel whith recently. I still can't quite believe how good these hubs are.
The freewheel is in a pretty decent condition. It might not look like that in the photos, but the sprockets don't have much wear. It's a Suntour New Winner with 13-14-15-17-19-21 gearing. Of course now, because it's been getting blasted with penetrating oil, it will require full overhaul. Which will be interesting. I have Suntour tool for that, but I think I will have to do more research into how one actually is supposed to use it. As well as figure out how to remove individual cogs from these freewheels, because I never succeeded with that so far. Thankfully I have other Suntour freewheels, so there's no rush with this one.
Now let's hope the penetrating oil will work just as well on the stuck stem and BB fixed cup.

Just finished my latest project, stripping my custom paint Gazelle AB 1986 and changing all components from Shimano 600EX to Campagnolo Chorus C-Record. Unfortunately it is pooring with rain over here so pictures of the finished bike will have to wait till after the weekend. But to remember what is was like I have a before-picture.

Had to replace this bushing after experiencing wobble that was causing shifting issues. Good product.

1973 SekineSHR
I think this is a 1973 SekineSHR. It has chrome-moly double butted tubing (it wouldn't surprise me if this were just the main triangle though) and a nice parts mix (suntour derailleurs, dia compe centerpull brakes, SR crank (I think it's that weird SR crank with an odd taper though)). This bike has a nice paint job but that's true of most of the Sekines I've seen. I like the chrome socks and 1/2 fork. The drop outs look decent but I don't recognize them. I think they're some sort of forged drop out.
I plan on entering this into the $100 challenge as I bought the bike for $20 and it has nice tires which is usually the most expensive thing to fix on a used bike. It does have steel alloy rims though as I'll need to swap those out as well as the fugly saddle. My goal is to keep my total costs (exclusive of time) to $30-$40 to get it into A1 riding condition. This is how the bike came to me in the wild:

Trash Panda Special Projects
Well with spring just a few more months away, it’s 36 right now, the crew here at Trash Panda are lazily working on some of the smaller task to get ready for the sporting season.
The colorful Cornelo in the stand for a little dusting and I was hoping new tape
I love the classic look of this bespoke artisan hand stitched suede but I just need a bit of padding and fatter bar. I do admire you guys who ride roads that rival the famous cobbles of the Hell of the North and gravel grind on suede and cotton tape but It's just not for me.
I hadn’t realized I actually did the the correct way when I installed it way back around 2009.
A tool I didn’t think I’d ever use working on a bike. Yep still donning a mask occasionally, mainly when it's cold and windy early in the morning waling to the truck and I had a terrible cold this week so in deference to my fellow Americans I was using one in stores.
Sadly today’s project is “AWoP” {awaiting on parts} as we used to say in the Marines. sadly I tore the new covering and now need to find a new one.
Does anyone know of a source of these in red?
