Just checked with the original owner: 'tis a 1969 (if not a 1968). That's fourty years old!!

I mentioned to a friend of mine that I was interested in a frame, so as to have a permanent bike on the turbo-trainer...

...he offered me this Bob Jackson frame, however when I learned about the history of the frame, I HAD to build it up properly.

He ordered it from Bob Jackson WAY back when he was 18. He had to wait months and months for it... and he's had it ever since.

It has been resprayed/modified a number of times. I'm told that back in the day, it was a race frame.

Some of you may disagree with old-meets-new style of bike build. I have my reasons... and they are:

1) Money - I have many of the parts already
2) Personal preference - I quite like the idea of it!

Enjoy the pics:


There's something about that logo that I love.
Image


My build so far (before the final respray). Cinelli bars and stem not fitted yet.
Image


Yes, that's right. 40 year old 531 tubing.
Image


Old canti-bosses & bridge were SO outdated that I had to remove them. I couldn't get anything to fit. They were awfully close together... so goodness knows what was fitted on them originally.
Image
Image
Image


Rear derailleur is an Ultegra SL SS.
Image


Front derailleur is a 105 (double probably).
Image


Cranks will be FSA Gossamer Mega Exo Double (in black). I stuck my triples on there just to check the chain line... and it's a no go.
Image


Cranks and BB cups fitted (not the final items).
Image


My choice of wheels (heavy but decent quality IMO).
Image


Front complete with brake. I had to drill a bit in order for the frame to take an 'allen' fitting caliper.
Image


Rear complete wirh 8 speed cassette. 10 speed wouldn't fit in the frame... PLUS I couldn't get downtube shifters in 10 spd, so 8 will do. Rear brige is blatently much higher than the front - therefore will require a very long drop caliper (ordered a dia-compe caliper - on its way).
Image


Good clearance in case I fancy a touring tyre.
Image


My choice of pedal (50% off means it becomes my obvious first choice!!).
Image

I happened to have this lying around...
Image


Teflon cables.
Image


I'm not sure about these brake levers... they look uncomfortable. I may change them to something else.
Image


Opinions/comments welcome... just please be tactful.

Yes they are... but Argos removed the old bosses. I did the drilling for the brakes.

My friend only gave me the frame unfortunately. This is the best I can do for now...

...PS I might be able to get hold of ancient dura-ace shifters if it makes you feel better!

:)

Good project mate, going to be nigh on impossible to source period correct components for that setup so I see no probs with sticking new parts on it.

1969 the summer of love, even I wasn't born then. Makes me feel young again and reminds me of old racer projects that my dad built up way back in the 70's :)

Would the canti bosses not have been for cyclo-cross type brakes? Did you try these?

I couldn't get anything to fit...

...the bosses were too close together, so nothing would work.




The frame was passed down to me by it's original owner.

It was originally a race frame, with various bits added to it over its lifetime (to turn it into a tourer). It has therefore already been 'butchered' a number of times over the years!

The current rusty paintjob is not even original.

Steel frame = Frame for life... Strip, mod & repaint as many times as you like IMO.


Latest Photos:

I went for the Shimano R400 brake levers in the end. Much comfier, and the quality if much better.
Image


Cinelli stem. This will be pilished back to the original aluminium finish,
Image


Cinelli bars. These will be polished down so that all scratches are removed out of 'sight'. Areas under the bar tape aren't a concern to me. Logos may disappear.
Image


Dia compe rear extra long reach caliper arrived. I had to modify it in order to fit the new 'allen' fitting. I wish I had left the rear bridge alone now!!!
Image


The Dura-Ace shifters I sourced were a bit rusty and looked a bit sorry for themselves. Furthermore, I suspected that they were 9 speed (as opposed to 10). Not happy with the finish, I returned them in order to get some brand new R400 shifters. Much better IMO - I love the heavier metal finish.
Image


That's it- I'm pooped. Nite nite.

The narrow bosses were for Mafac cantis.

Hiya,

I have checked with the original owner, and the bosses were added to the frame 15 years after it was purchased... so they were designed for something available at around 1984.


If anything... I've returned the frame to its original condition (although I haven't removed the rack mounts, or dynamo mount - which were also added in 1984).



UPDATE:

Here's the promised compact double. I've gone for a 34/48.
Image


Bottom bracket spacers. My knees prefer it, plus it'll help the chain line.
Image


Checking that cables etc all fit and are good to go:
Image
Image


Compact fitted with pedals:
Image


So far, so good:

Mafac or Weinmann would have done the close clearance cantilevers
