Raleigh SP 1000

I hate to say it, but if 20yrs is classic, 40yrs is vintage and 100yrs is antique, this fits in somewhere. If not, wait around awhile...
This is a good place to document unusual bikes and this one, is that for sure.

The Cobb salad of bikes, this is made of four different metals. The triangle is titanium, the lugs are aluminum, the fork is 531 and the stays are 753. It weighs 5lbs 3oz. As pictured
This came into the shop in seriously funked up condition. It had been sitting outside for years.
Being bonded, the corrosion under the paint on the lugs makes it a no-sale here at the shop, so I've decided to have it blasted and powder coated sometime in the future.
There isn't much info on the interweb concerning these but from what I've read they are pretty rare and were quite expensive when new.
Does anyone have any insight on these?

What a shame they let that deteriorate. Hope you do get it resurrected.

So the powdercoaters said that the spray would be inconsistent because of the bonding and the need to have it all electrically charged. I can see that, so I'll re- do this one myself.
While I'm at it, and since this thread is already here, I'll document it here.
First....
Since there is no hope of getting it back to new stock condition, this will be a custom.
All parts will be sourced used at the shop if possible.

• chemically stripped
• steel painted black wrinkle
• Titanium seatpost and bottle cage bolts
• Shimano 105 Bottom Bracket - octalink

The triangle will be painted also.

Turns out, powder coating, or doing anything to these Dyna or technium frames that heats them up, compromises the glue that holds them together. There is a recent video online of a guy in England restoring one of these Dyna Techs and on his test ride, the head separated from the frame. He got it on camera too.
A little disconcerting....
I guess I'll keep my eye out for a replacement frame to hang all these parts on. Just in case.
I guess it just makes sense, they are put together with glue after-all.

Well, to continue ... Gulp....
It's finished being painted. I've rubbed every centimeter of this frame by now and there is no separation or cracking anywhere so I will continue
More parts from the bins.

• Kenesis carbon fiber fork, 1" x 11.75" steertube
• Threadless 1" ultra lightweight headset. It's not marked for maker anywhere.
• Spacers and stem from the bins
• Used seatpost and seat from the bins
• Dura Ace 7800 brake calipers

I've decided this will be a 10 speed with a click- twist shifter so the downtube shifter bosses have a cable stop on one side and a handmade blank on the other.
