My 1987 Centurion Sport DLX - In glorious teal

This is a semi-cross-post from the Road Racing forum, but I was told I should probably post it here instead. I've edited it down to just include the important bits, but if you want to read the short story - http://www.bikeforums.net/showthread...t-REAL-cycling

My 1987 Centurion Sport DLX.

This was a 'shed find'. It was my brother's bike. He owned it new. It was bought from Brown's Bicycles in Beverly MA, just like every bike I've ever owned.
It was absolutely filthy. Probably a half inch thick layer of grime from being in the shed for easily 20 years. The tires were dry rotted... but that seemed to be about it besides the filth.


Here's the bike after a 5 minute wash with some water and a crappy sponge.



Once I cleaned it up enough, I threw a leg over it... it actually seems to be the right size for me. It must have been MUCH too big for my brother. He's a bit shorter then me, but I think he MIGHT have longer legs. Hard to tell what size he was in 1987 (he would have been 14 and probably 5'9" or 5'10")




The whole time I'm yanking this thing out I'm snapping photos and throwing them to my friends who are Cyclocross people and they were telling me some things I needed to know. I tested the brakes, the cables seemed in good shape. I tested the shifter. They all worked smoothly. I was really surprised how it worked. So, I had the guys give me a parts list of things to buy:

Brake pads - http://www.amazon.com/dp/B001CJZ2S8/..._26725410_item
Tubes - http://www.amazon.com/dp/B000AOA14G/..._26725410_item
CX Tires - http://www.amazon.com/dp/B000A0KZ1O/..._26725410_item
Rim Tape - http://www.amazon.com/dp/B001AYCJ6S/..._26725410_item
Tire Levers - http://www.amazon.com/dp/B000IZGFCE/..._26725410_item

Parts should arrive by this weekend. My brother-in-law is a pretty serious cyclist and he's going to help me go over it to make sure it's safe to ride.

I hope the tires fit. That's the only unknown right now. The stock tires on this are 32-630. I've read these Kenda K161s are about a 29-630 (though are advertised as a 35-630, they're universally reviews as SIGNIFICANTLY narrower)
If it all goes together and the brake and gear lines aren't rotten, I should be riding by Sunday. I'm excited.

Now, this is my FIRST road bike. Besides a helmet, what gear should I get to ride this thing comfortably?

What else can I do to clean it up as much as possible? There's a lot of grime still in the corners.

I think I should clear those tires.

Free or not, thats a great bike! Even better that its free.


I would grab a new chain and freewheel. If your brother in law has a few tools I would also rebuild the bottom bracket with some new grease as well as the hubs. If the brakes are working well you can just put some oil into the housing but I would do new cables and housing.


I would also change the bar tape but thats just asthetics. But youve got zero dollars into it so pick up a few parts and youll have a great bike for a long time!


Congrats!

I see that the Freewheels are like $10, I might do that and grab a new chain.
Anyone know if this rear derailleur will work with a MegaRange gearset?
I'm also thinking of upgrading to a dual pivot brake caliper setup

I would change the cables and housing also. Those cables look pretty rusty and most likely will not operate smoothly. This can affect braking and shifting performance. To be honest, that bike could use a complete disassembly, cleaning, polish, and regreasing of all the bearings also. It would be the perfect bike to learn bike repair on, as it looks to be in ok condition, and would be decent once that work was done. I would get a basic bike repair manual. I liked having a book because everything was in one place, no hunting down info piecemeal.

I'd love to strip it down and do a whole cleaning eventually, but I'd like to at least get riding first. It does all operate smoothly, which kinda surprised me. there's a bit of rust on the exposed ends. I'll see if I can get some new cables on my next paycheck.

so, I guess Facebook changed the way they allow me to link photos... and subsequently killed all my photos... again.
hmm. I'll have to find a way around that.



So, today I rebuild the front and rear wheel bearings (the front was seized), tubes, tires, cleaned the frame a little more, lubed the chain, wrapped the handlebars with new tape.
The brake and shift cables were totally fine. I'm rather surprised. I may still do them later for piece of mind, but for now they're great.
I didn't even need to do the brake pads. these actually aren't all dry rotted at all.

Some minor issues I'd like to address eventually.
I'd like to upgrade to 700c wheels. I would like to run a cassette freehub wheel, but I don't have the funds to change the shifting system to a 7speed. I may even just consider gettng a 700c freewheel.
I'd like to get new pedals and maybe get this system: http://holdfastordie.com/store/foot-retention-system


It rides pretty good. I may put the suicide bars back on until I get used to riding with my hands on the hoods.

My first successful commute!




There were some questions on fitting the tires through the brakes on this. no problems:




Yay, new grip tape:

My brother in law did this for me. He's a bit out of practice, but it looks fine to me. Better than rotten foam.

I'm thinking of getting fenders for the bike... any suggestions?
Also, looking to get new brake and shifter cables. I don't need anything fancy. Any suggestions for something affordable? Also, anyone have any suggestions on colours?

Black fenders would look hideous.

http://www.amazon.com/SKS-Commuter-B...fenders+silver

Cables and housing?

Go to REI or your local LBS and have them sell you what you need. White or silver/grey housing. Spend the extra few bucks on stainless. Grease the cables before insertion into the housing.

I'd have used white bar wrap too. A PITA to keep clean, but much nicer look.

Level out your saddle, nose is too high.

Get some Mother's aluminum polish, $7, to shine up the brakes. Get a brass brush to knock the rust off the chrome parts.

Up above, you mentioned going to 7 speeds, but Salem's pretty flat? Needed? I lived in Marblehead for a summer to work at the Eastern YC.

ENJOY!

Yeah, I think I might stick 6 speed until I determine a need for more.
yeah, I need to shine the brakes and chainring up. I've got a crhome BMX bike and it's such a pain to keep clean.

would those fenders fit over 27s?

I wish I was home this weekend to go to the vintage bike show in Boston.
Anyone ever tried this cleaning kit?

Not necessary, go with oddjob's suggestions. Don't bother with the rust on the brake pad bolts, new pads come with new bolts. Mother's mag and aluminum polish will make the aluminum shine. If you want less shine, you could always get some automotive paint rubbing compound, works on the paint and aluminum. Rub it in with a moist cotton rag, rub off with a clean cotton cloth. Clean the dirt off the parts first with something like Formula 409 or give it a soapy wash, whatever you prefer.

White vinegar also works well. Throw it in a plastic container, put your rusty bits in, let it sit for 30 minutes and then scrub with a brass brush. Repeat until clean.

Then chrome polish + brass brush. That should do it.

Yes they're a different diameter. If you're really on a budget walmart carries a $7 complete Bell kit.

I bought this for my derailleur cables:
http://cgi.ebay.com/ws/eBayISAPI.dll...E:L:OC:US:3160

I got Jagwire OEM cable for my brakes
Both in white.

Eventually when I can spare some more money (or if attempting to re-use my brand new black bar tape fails...) I'll rewrap with Pink Roubaix tape

Things left to do:
Install the RetroShift CX1s with the NOS Shimano 105 shifters and cables I just bought (and hope I can mount the FD shifter to the stem for now)
Install new brake lines when they arrive this week

upgrade to dual pivot brake calipers
buy and install a modern 6 speed Shimano freewheel. Mine has the old style freewheel where the gears are just totally square, so shifting gears is a bit jolting.
Maybe try to find some nice 700c freewheel wheels to thread my 6 speed freewheel on
maybe upgrade the rear derailleur to a 105 6 speed and the front to a 105 double. I'm not sure yet. The current stuff seems to work fine for now.
