Ruined bike parts needed

[Johan Bornman]

I need sample bike parts for my bike mechanic school and I'll appreciate it if you have some scrap lying around.

 

I strip these parts down for an exploded view, cut them in half or just practice on them.

 

We need:

 

   All types of MTB forks.

 

   Brake calipers (hydraulic and mechanical)

 

   Jockeys

 

   All types of gear shifters/brifters

 

   Hubs

  

   A frame from which I can extract the head tube and BB shell.

 

 

    BBs. In particular I'd like a DA Octalink, of the doomed Shimano design with roller bearing fame.  I already have ISIS, square tape and cotter.

 

It doesn't matter if these parts are grossly damaged. They're purely for demonstration purposes.

 

If you can help, I'd appreciate it.

I have a stuffed 105 Octalink for you and with some digging I can find alot more intresting broken components.

Johan PM me I have a lot of old spares lying at home old MTB fork, BB's , brake Calipers.

[Johan Bornman]

Thanks Samjoor and Wagon. I'll PM you for addresses and stuff.

 

Still looking for an hydraulic brake caliper, badly indexed headset or two and broken hollowtech cranks.

The headset on my "new" Kona is in a bad state but I will have to see if it is indexed. I also have a set of FSA Mega Exo bearings although most of the damage is cosmetic from ham fisted mechanics.

do they have to be ruined? Will just plain old old and disused do?

Of course not, new Campag 2008 gruppos and Zipp 404s also welcome.

 

Just joking, it is a good question. I want ruined headsets so I can show the unique pattern they wear down to. But I also like to show the various types, so those don't have to be ruined - a disused or unwanted orphan is fine in that case.

 

Same for some of the other parts, it is always useful to show how they fail and then draw the conclusions as to why they failed. 

 

I've been taking my MTB's suspension fork apart for each class but it is getting a bit tired of my antics. I'd ideally like an old fork that I can dedicate to open heart surgery.
