1989 Diamondback Ascent EX

Cheers. Sounds like a good find Mahoney.

Giving the frame a little clean up today and spotted the numbers on the BB shell under the cable guide.
Anyone know anything about DB serial numbers?

Numbers look like 3A014
and
F9050514.

Re:

I'll check mine if you remind me, but from memory it also starts F90. It's the 1989 Axis in the picture above.

That'd be cool if you could. Nice bike btw.

Thanks. There is a thread on here about it somewhere.
Serial is: 88M2069
I think the F90 one I was thinking of was an Explosif I used to own.

Cheers Rampage. So no obvious sequence in frame numbers then!

The few new parts needed for the build have arrived.
Just grips and cables were needed, but I thought I'd treat the old girl to some new tyres. Nothing looks quite so good as nice fresh amberwalls and as this will be a rider I didn't want to be sliding around on some perished old rubber.
So a pair of Smokes were ordered from our German friends.

and fitted.

Re:

Mine claims to be made in Japan. Yours is more like the Taiwan style serial numbers, so that could be why they are so different.

 

[firedfromthecircus]

Ah, yes. Mine is Taiwan made.

Not a huge update but progress on a couple of things. Rear hub is now spaced to 135mm. To save cannibalising a good hub I bought a 5mm spacer from SJS. The axle was just long enough to get away with it. Also got a better set of rings fitted to the crankset.

And thanks to Maksters Overburys build I now have instructions for the stem pulley.

So here is how it's looking now.

What does the pulley do?

Re: Re:

I'm guessing it's a cam system that varies the power depending on the positioning.
