Dragging you back to your component list, Cinelli bars shallow drop Model 64, 40cm wide or 38 to save a few grams. What rims? # of spokes?

There you go again, rantin' and...

Whatever ballpark you think the weight should be, just keep going up

Okay well I picked up some shifters for the bike.

Not sure why everyone thinks these are so special!


Just kidding, they're kinda cool, and pass the ‘50ft test’ with ease, but! I've got an issue that I need the collective's wisdom on.




I surely would have thought my 'carbon fiber' () shifters would have been it’s equal in weight - but who knew carbon fiber was so heavy! Geez it's like lead!!!



Okay, onto the issue. I circled it in the picture below. See all those tiny little cracks in the chrome? It's obvious that this is a weakened area of the metal, no doubt from removing it from down tubes who knows how many times over the last 40+ years. Okay. So, when I go to put this on the bike...no 'test fitting', when its on, its on, and I will try to place most of the stress of bending open the clamp on other areas of the ring.


Question is - how serious is this? There was one other auction for a pair of these that I was watching, and the lister was very forthright and mentioned the damage to the clamp, and it was pretty obviously bad. I didn't see any bad areas on the auction for this one (and honestly maybe the seller didn't see anything either). I'm not interested in going back to the seller for anything, but what I'd like to ask y'all is how serious is this? It seems to me like it may be a common issue, given that the only other one I saw (that was SR, at least) has this same stress area.

If nobody's worried about it, I won't be either. If you are, well then I guess I still won't be cause there's nothing I can do and no way I'm going to drop even more $$$ like $30 or more for just a new ring. I'm glad to have the whole kit 'n kaboodle with the shifters now, and since the ethos of the build is turning into 'Super Ultralight Weight Weenie Huffy Boat Anchor' build energy, these shifters are not going to stay stock.

Just picture if you are trying to weigh a skyscraper, and you want to know how much weight you'll save by taking a tiny chisel and knocking some chips the size of a few granules of sand from the corner of a piece of stone on it, and you'll get how I'm spending all my valuable time these days.

Who was it, I think it was iab who mentioned in another thread of mine that the life I was living caused him no longer ever feel bad about his?

No, iab! Feel the joy!!! Take my thread here as an example. Everyone should want to take an old worthless barge of a bicycle and waste huge amounts of money on it for absolutely zero reason. Feel the glow!!

I just want everyone living their best life, is all.

I would look at it as an early warning that fatigue has started, but it should be safe to use. I have broken a downtube cable stop from excessive swapping between bikes. Since then, I leave clamps opened up after removing from a bike, and put them together only when remounting to a bike. I figure that cuts the number of fatigue cycles in half.

They are inevitable with the shifter bands it seems. Gran Sport, NR, same. If it breaks I think there is a way of attaching it on a campy shifter mount perhaps?

stoneageyosh

It may be the chrome plating not liking being stretched repeatedly. Is there any cracking of the steel visible under magnification?

RB1-luvr

ooo, I would do this to those shifters:

jdawginsc 

I think you should have the stem, Fork crown and crankset pantographed with Huffy...

A bit too much alloy removed for reliability's sake. Ask me how I know:



Alternatively, these were much stronger in use:

Mill out a big hole in the shape of a clover in the underside of the bottom bracket.

AdventureManCO 

Dude that is such a rip off of Colnago, Masi, etc.


In other words, I love it and will absolutely do it.



However! We can't just do a clover - we have to be better, in every way shape and form. I was discussing this idea with another BF member, and the discussion centered around an 'H' cutout.

Look for it soon.

smd4

Put this in your milling machine: Four leaf clover.

You’re welcome.

jdawginsc 

Some ideas for stickers or bottom bracket cutout!

sbarner 

It has been my experience that this is purely cosmetic cracking of the chrome plating when someone removes the shifters or cable guide without taking special precautions to avoid it, which is to say just about everyone who removes them. When these came from the factory, they were in the "open" position, so they only needed to be flexed around the tube to be mounted. If you are not extremely careful when either removing or even attaching them, the band will want to bend where it is easiest to do so, and that is at the narrowest point. When removing these, my 'trick' is to insert the largest pin punches that will fit into the bolt holes on both sides and then to carefully pull down while pivoting them out, doing as much as I can to distribute the bend over as much of the band as possible. If the bending is distributed around the band, instead of being concentrated in one place, I can usually avoid any cracking of the chrome. Of course, the eBay flipper who is parting out the '74 International that he just bought as a yard sale isn't going to do that, and then he's going to bend it back for the photo, so pretty much any used clamp that you find on eBay has these cracks.

Not to worry if they are there, as the steel in the band was selected for its malleability and can be flexed many times before it breaks. In fact, I don't recall ever seeing one snap. The failures I have seen, other than rust, are with the attachment of the lever stud to the band. Brush a little chrome paint into the cracks after mounting and no one will notice. They're going to be looking at the spacer you use to get the clamp to grip that 1" tube and are not going to notice a defect in the chrome. Sort of like seeing Phyllis Diller in pearls. The shock to the senses will distract from trivial defects.

AdventureManCO 

I really appreciate that information about the clamp. I don't appreciate anything else though!

RB1-luvr

Is it wrong that the first thing I do when I get to my work desk is check this thread?

AdventureManCO 

Yes

AdventureManCO 

Okay! So I'll try to work on the bottom bracket cutout this weekend, while I wait for a few other items to arrive that will push the build into overdrive. I looked the other day and I actually do have some aluminum plate, which is great because I can start fabricating some stuff. I have some ideas that I'm going to use that I've never seen on a bike (surprisingly), and it is pretty legit. I'm surprised I've never seen it before, so what better place to display it than on a garbage bike.

So for the bottom bracket, these are the top two contenders right now for design.

The Masi ripoff:




The Colnago ripoff:



Thoughts either way? Anything I'm missing that I should know about? I'm not favoring one over the other, and both should be equally time-wasting for me. Time to vote or offer up an alternate!

AdventureManCO 

I guess this would be a more accurate ripoff. If we are going to parody let's at least be true-to-form:

smd4

Four-leaf clover will be easier to fabricate--drill four holes and file between them.

BFisher

The shape of an anvil or some other weighty symbol could make a nice cutout. Be warned though; with the way those shells are constructed, a large enough cutout may render it too weak to handle high torque loads.

smd4

How 'bout a nice anchor? Could also symbolize hope--something else this bike may need.

So, frame and fork (including crown race, but excluding rest of headset) come to ( 2,877g + 969g ) = 3,846g - or just under 8 1/2 lbs.

Not exactly a "ballerina" - but not exactly a "sumo", either. If I recall correctly, I've seen good steel MTB frames (e.g, an older Bianchi? MTB frame, I think) listed for sale with measured weights in that ballpark.
