Shimano Aero AX gruppos
Postby koen » Sat Mar 01, 2014 12:53 pm
I'll dig out the catalogue I have and scan some of it in too.
I am just putting the best gear back on my old Madison. Its not worth anything, heavy as, but I like it anyway.
These are two adamas rear mechs. One made june 81, the other April 82. There is a minor change in that the first has steel parallelogram.
The chainrings on Adamas is a very light assembly on a splined bb with splined cranks. Only the 'pickup' teeth are steel

The pedal bearings are a bit crunchy and stiff - any info or tips on opening them up and servicing them? I also got a set of reducing adaptors so I can attach normal pedals but they're steel and weigh a tonne so if I actually get the cranks cleaned up and want to use them I might get some alloy adaptors made.

Opening up some details about the gruppo family I didn't realise.
Did the Adamas group have the funky big pedal attachment size?

I'm restoring it as we speak.
See thread here: http://www.bicycles.net.au/forums/viewt ... 23&t=72674" onclick="window.open(this.href);return false;
KGB, the pedals are quite easy to service, mine were all stiff and crunchy as well as the grease had dried up. On the back of the pedal there is a big Allen
bolt. Just undo that and the bearing assembly will come apart. There are two separate bearings (all loose so be careful), just slowly pull them apart and then clean
and re-grease. Its easy. Mine feel like new now. I had to do the same with the bearings for the wheels and BB/Headset.
I'm not sure how well the AX will work but it's beautiful made and has "quirky" value. It polishes up nice as well:
Cheers....

When I bought my McBain it came with an AX stem and AX 'aero' seat post to fit* the Tange Aero tubing. I originally wanted a full AX groupset, but soon discovered it only came as a road group, so just kept the stem and seatpost. I kinda like how optimistic the early 80's aero thing was; as if a slightly modified shape was going to really counter the big chunk of flesh and bones sitting atop the saddle!
I polished out the silkscreened D-A AX logos which were pretty banged up anyway. The stem was missing the cap when I bought it, so I had a buy a whole new stem just for a cap!
If money (or time) was no object I'd love to find some AX bars to put on it as there's not many bars that match the AX stem's 26.0 clamp. The grub screw seatpost, er, binder is arguably the worst thing to come out of that aero period.
* It doesn't fit very well.

The 600 brakes had a cartridge system that is close enough to modern cartridge brake pads, however the Adamas brakes fit directly into a rectangular space and are held in by an M4 bolt with a captive nut.
I'm thinking that perhaps a pair of the bolt on skinny V brake pads might be able to be shaped to fit, however the bolts are typically M6. If I can make the back of the pads fit into the recess then I can drill the hole out to suit. Whilst I am loathe to drill holes OR otherwise permanently modify the calliper, I would rather have brakes that function than maintain their originality.
Does anyone have a better idea?
Cheers,
Cameron

Now all I need to do is find someone who can get them in...
Do you happen to know any purveyors of rocking horse poo? Oddly enough no-one seems to stock pads that were only made for one model which was last manufactured over 30 years ago.
I have made a couple of calls, but the item number doesn't appear on the stock lists.
The right part would be much better than mutilating stuff.

Cameron

Abbotsford Cycles, who have a good reputation for finding rare stuff have come through. A set of salmon pads now on order. Not cheap, might take a while, but in the meantime I now have an reason to give the brakes a clean and polish.

I need to get some pads for the GB Courer and Weinmann shoes. I will also give Abbotsford a try before ordering from overseas.

Good summary, but show me a SP-7300 A-type seatpost which is round all the way.find_bruce wrote:We seem to be drifting away from frame weights.
As you say Velobase is good, its not god. Looking at the catalogue photo of the 3 posts, I see standard round with fluting, round insertion with aero top and oval insertion with round top. I haven't seen a 7300 standard round seat tube with or without fluting. The way I read it is
- 7300 A-type - standard round seat post - ie round all the way
- 7310 B-type - round insertion, semi oval aero top
- 7320 C-type - tear drop insertion, round top
- 7322 E-type - oval insertion, round top

It is consistent with 7400 with A type being fluted & b type having the aero top. Only place I have seen one is page 16 of the 1982 shimano cattledog you linked toP!N20 wrote:Continuing on from this thread.

But there are plenty of dura ace fluted 7200 & 7400

The Shimano Positron AX (AX10) manages to bear two of the most infamous monikers in Shimano History - ‘Positron’ and ‘AX’. All it needs is ‘Biopace’ shaped pulley wheels and the set would be complete. In marketing terms, it is the kind of laughing stock that gets laughed at by other laughing stocks.
