A basement queen for me?

It would seem as though I have finally procured a basement queen in a size that fits. I believe it to be (judging by the serial number) to be a 1986 Panasonic Sport 500 ten speed with working, all original Shimano components. The paint still has its luster and only as few scratches. The 22 year old tires and tubes still held 70lbs of air. Its made of 1020 steel and cost me all of 15 dollars. I lubed it up, un seized the front derailleur cable and rode it around the block a few times. Man this bike is fast! Now I need to figure out how to tighten the brakes up and get the rear derailleur to stop jumping gears.

So far my plans are to replace the cables and brake pads, then figure out how to keep the gears from jumping.

I did notice it to be a bit odd. The tires are 27in by 1 , Ive never saw rims nor tires of this size. Do they still make new tires, tubes, and rims this size? Lacking that what would the possibility of converting it to a fixed gear 700cm wheel set? I think clearance may be an issue. Either way I figure I got a nice little bike to play with.

Here she is after a quick bath, had to get the last 15 years of dust and spider webs off. I would have spent more time cleaning it but the weather didn't agree.

Nice find! And yes, there are 27 inch road tires still around. You can convert MOST older bikes to 700c, but I'm told it's a.. process.

As far as 27 inch tires, I know that Specialized makes one of their road armadillos in a 27 x 1 1/4. Not sure on others, though.

27 1/4 was a common size in the 70s and 80s. I would just stick with the 27s rather than convert to 700cm rims.

27 inch wheels, tires and tubes are still fairly easy to come by, as obscure, outdated bike parts go.

tubes won't be labeled as such, for the most part, but just ask your lbs for 700cc tubes that will fit, and
remember what size they give you...

700C? Yeah, Convert to 700C is doable, easily. Your brakes have sufficient range to adjust for the wheel radius difference. You have 126MM stay spread, though. It can be spread for 130 MM spacing wheels though with that steel frame Good find!

It's not so tough to do. Build up a pair of 700c rims around the hubs from the 27" wheels (that way you keep the current gear cluster) and swap the current brakes for a pair of long reach calipers.

This sounds like a job for...someone from the LBS. Good to know its doable.

In a pinch (or if you are cheap like me) you can get 27x1-1/4 tires and tubes made by Bell at ACE Hardware or Wallmart (really cheap). They seem to be ok quality to me, I use them on my 1969 Schwinn Varsity.

I have the Bell tires from WalMart on my Raleigh. I have 500 miles on them with no problems. I think they were $15 or so.

A Panasonic Bicycle was the first '10 speed' I had bought in a long time and that was a long time ago. I can tell you this, it was quiet. It shifted smoothly and I never had a problem with it, although I caught a lot of flac from folks because it was a Panasonic.

Does it have a radio? etc. etc. etc.............

Sounds Good To Me

I wouldn't bother converting the wheels on a $15 bike unless you wanted to upgrade the whole thing (new gruppo, bars, etc.). For now, I'd replace the brake blocks, tires and tubes, cables and housings and check the chain for stretch. Also check the wheels for true. Replacing the cables should help w/ the skipping derailer since you have to adjust the whole thing when you replace them. Enjoy!

Awesome!

I love them 27" wheels!

I'd stick with em, you'll love em too.

Very nice, I'm sure you are going to have a blast.

Go to expertvillage.com or youtube and search for "how to do bike repairs" there are videos that deal with adjusting the brakes and changers, and a little bit about the driveline issues.

If the bike has sat for any length of time, the chain could be binding. put it on it's smallest chainring and sprocket and look to see if any of the links are binding and not fitting the small radius.

I used to find that a lot, and a good soak in oil usually frees it up. Otherwise I've used a chain breaker a time or two to loosen up a binding chain.

Enjoy your bike,

RD

I, too, found a similar bike at a garage sale for $3 (yes, that's a three). It's steel, lugged, and the only identification is "Specialized" stamped on the chrome chain stay guard, looks to be late '70's vintage (pic attached). I have about $75 into it as shown, it rides like a dream (after a thorough cleaning, re-lube, etc.). I plan on buying a new set of 27" aluminum wheels from sheldon brown (www.harriscyclery.com). He has some great 27" 36-spoke wheel sets for about $100-up. You can't beat the price for this level of quality even if you build them yourself. That would be my suggestion!

In my sig there's a whole section dealing with my problems with 27" wheels. They don't make good rims in that size anymore (though you might find a used one that's strong) - I don't know how heavy you are but I'd say if you're north of 260 you may want to start looking into replacing them with 700c (borrow a 700c wheel from your lbs and see if the brakes will reach (extra travel in the arm)).
