boy"O"boy's 1989 Ridgeback 604 SIS

[boy"O"boy]

Hi all.
Slight progress on the Ridgeback today.
I had all intentions of finishing up the build, but like all well laid plans it didn't work out that way.
Hopefully more to come tomorrow.....but I can't promise I'll finish by then.

Here's where I'm at -






Work since last update
- Stem repainted in RAL 9010 pure white
- Original bars added. Had a 2nd pair painted in RAL 5018 turquoise but they wouldn't fit through the stem and started to scratch..... reverted back to originals instead.
- Blackburn MTN bottle cage repainted in RAL 1018 Zinc yellow and added
- Biopace chainrings sourced and added to polished M730 XT cranks
- Early Avocet R20 saddle added.
- Ritchey Megabite 1.9" added. Massive thanks to @ratcapa for these hard to find tyres.
- M732 XT 2-finger levers/ Thumb shifters/ Grab-On MT2 grips all added.
- M730 XT Q/R wheel and seat levers sourced and added


Still to do.
- Chain and gear / brake cables and set-up / Index
- tighten hub cones
- Add pedals. I've got M735XT going on but long term would like to source some good condition M731 XT pedals to complete the catalogue spec.

More to come.
Cheers

Looking good

So.... after a 2 week break for the family holiday, I was able to find time today to finish up the build.
I'd say it's finished but to me... finished has to be rideable.
The rear hub spacing is causing the 7spd cassette to touch ever so slightly on the inner chainstay and is causing drag that's effecting the chain running smoothly. When the chain is in the lowest cassette position it jams.
To remedy this, I've got to adjust the axle spacers and re-dish the rear wheel slightly.
But....I couldn't wait to see it complete so even though it's not running properly yet, this is the complete build. The only changes planned are a nice pair of Shimano M731XT pedals. Just waiting on a nice pair to appear....the M735XT were destined for the 'Iceman' and since it's finally home, certain components 'borrowed' from the parts stash will have to be returned from a couple of builds.

Anyway. Here it is.

More detail pics






Build spec to follow but essentially it's the '89 Freewheel catalogue spec as page 1.

The search continues for a fillet brazed 605 SIS in the same 20" size to complete the set. Patience is a virtue. These things turn up eventually! ....and the faith is strong after the return of the Iceman!

Cheers all.

Looks fantastic!

What a great looking machine from that amazing Freewheel catalogue that must have kept many of us occupied for hours on end! Well thumbed is a phrase that comes to mind!

Cheers! That's the 604 SIS now finished....I'm hoping that if I bide my time, the catalogue matching 605 SIS in 20" will eventually turn up.
The 2 examples I've seen here are both in massive 22" frames....so Ridgeback did sell some!

Don't think I could make those catalogue wishes a reality!! - bit like Kelly Lebrock in Weird Science!






Rear axle spacing now sorted so the cassette locking/7th speed doesn't foul the frame and drag the chain. Rear wheel had to be slightly re-dished to centre the wheel alignment again. Gears re-indexed - now working nicely.
Just a pair of M731XT pedals to score now...but my work here is done.
Onto the Iceman prototype and finishing the Pro-flexes.
