now, why couldn't they have put a barrel adjuster on the eco? seems a trivial thing and could still remain more "eco" than the ti version

daka

I'll let the repressed retired manufacturing engineer in me speak for a second - Note that the stop on the ECO is formed from the same piece of metal that the parallelogram arm is made from. Other than the original expense in fabricating the forming dies, no added cost. The Ti version, on the other hand, has three additional components, a riveting operation and (likely) manual assembly of the spring and barrel adjustor. Definite increase in production cost.

thook

perhaps. otoh, instead of bending the metal over to form the cable stops, leave it flat and drill a hole using the same barrel adjuster as the ti. moreover, use the same basic design/die for the eco as the ti, just make it all steel as they did. one die...two different materials. save even more over having two dies (i'm no engineer, but i'll mildly play the devil's advocate, here )

daka

That component part in steel cost pennies, even with the cost of tooling amortized. The cost of assembling the barrel adjustor, if it had been in the factory where I worked, would have been more than a dollar. Not to mention the cost of the three additional parts.

I don't have enough experience with titanium to know whether the same dies could be used - off hand, I'd guess no, since the design of the die includes compensation for how much a particular metal "springs back" after forming.

thook

my point is really, daka, it would still be more economical than the ti. and, ultimately, i'm just finding something pointless to gripe about...lol. i do have the idea, however, to see if i can add a barrel adjuster to mine as the suntour downtube cable stop doesn't have them. may not be doable, but i'm gonna see...dang it!

daka

Point taken. The real cost difference in manufacturing is likely the more expensive raw material, the finishing and the absence of economies of scale. As to the adjustor, before indexing many derailleurs didn't have them. It only became important when fine-tuning the lateral position of the derailleur to correspond to an indexed position at the shifter was required. BITD, you'd only use the barrel adjustor, if you had one, to take up slack in the cable.

thook

exactly. titanium is just expensive. i also realize, with either version, the nature of it's multi pivot design is costly

none of my cyclone derailleurs have one, but ironically the "lesser" BL does. i like having one back there for more convenient installation and adjusting as cables stretch...ie. not having to fuss so much with the pinch bolt

I Think there was probably no incentive to add an adjustable barrel to bikes being used with friction derailleurs. It looks to me like a properly sized barrel adjuster screw and nut would fit and give you the adjustment your looking for. It's a little unglamorous so I'd use the adjustable down tube hardware. They will screw into frame lugs or, if none are available, into an old clamp on style derailleur minus the levers. Understand that the screws that come with the hardware may or may not work on the old clamp-on. Sometimes the screws that came with the levers are perfect and add a touch of class to the set up.

thook

what i have is a suntour clamp on downtube cable stop. i don't think barrel adjusters will work on it. i could give it a go if there's enough clearance from the frame to spin the barrels. otherwise, i have a late 70's 600 rear derailleur with an adjuster that looks like it might work on the duopar. i'm juggling honda work, little home repairs, and another bike build. but, i should squeeze in 15 min's tomorrow to look at the logistics for the adjusters

I was referring to adding a new adjustable mech. to an old set of down tube clamp on levers. I'm a fan of barend shifters for touring bikes. Sometimes I forget that not everyone has a box of old shift levers.🤗
It looks like this:

Royce Union has a certain cache so I'm a little sad to see it go. I realize Peugeots have a following too. Sorry to be a wet blanket but the vintage look kinda got lost in the translation. All that notwithstanding it's a nice looking bike and you look very pleased with the results and that's all that really matters.👍

thook

and, that's what i figured even if my reply didn't reflect that. i've done that, also, with an arabesque clamp on. require some dremeling to make the adjusters fit flush, but it worked nicely. i just don't want to run modern looking bits on my gran turismo. keep it vintage looking as i can

not the lightest frame I have but un breakable and reliable!

that is super nice!! is it indexed in the rear??

GeoffroyFromLux

Thx

Yes it is indexed; 7 speed

the barrel adjuster off of an old 600 RD will work on the eco with a little tinkering. however, i found the perfect solution for the suntour clamp/cable stop; jagwire mickey barrel adjusters. they can snug right up to the frame and still spin since the barrel has such a narrow profile. to top it off, they look the classic part....mostly . now i can fine tune both derailleurs

By automotive standards I think my '97 T900 is technically a year away from being 'classic', but close.....

Level top tube, silver components... "classic."

Looks great! Love to see more pix of it!

Ha, well...... originally it did have a black seat post, stem and chainrings. I took the opportunity to rectify the aesthetics while fixing the fit!

I got this 1973 Fuji Special Road racer at a online auction cheap last week.

ZudeJammer love it!! and, where'd you get that frame bag?? can't quite make out the brand tag on there
