I guess as this is my first post I'd post some nice pictures.

I bought these frames a while ago and am now starting to think about building them up. Not sure which way to go yet but I'm going to have the Spinergy's on one of the frames and would like a Tioga Disc Drive on the other. Any ideas anyone?

I'm guessing most won't know the differences in these 2 frames and the importance of one of them, anyway here's the pictures in case anyone does.

Thinking about it, these frames might even be earlier than this?

I was told the second one is actually one of the original B3 prototypes.
It even has oval tubing on the downtube and completely different bracing.

I went to look at a Green B3 and the guy also had these 2 so I bought them instead.

2 B3 frames
1 F4 fork
1 D1 disc brake

The first one is a later B3, when you had a choice of B3, B4 and B5 models, from around '97 I would guess. The second one with the oval down tube is a '95 B3, the same as mine. It's slightly different in that the head tube gusset on mine is on top of the top tube not under it like yours.

Hope that helps.

Why cry ??

You should see what else I have to unpack somewhere, untouched since around 1999. Grafton, Pulstar, Hershey, Paul and other things I've probably forgotten about.

It took a bit of finding, but here's a bit on the prototype B3's, as you can see this still has the twin down tube front triangle from the B2 but has the B3 rear features, which is the shorter shck set up in an attempt to reduce frame flex.

This is from MBA June '94.

Do you have a frame number for the oval tube'd B3?

The frame is C4061 and the later frame is C7648, wonder how many they actually made then.

It's a very early B3, so could be a pre production model maybe.
