The mystery of the damaged down tubes

[HomerSimpson]

[quote name=Johan Bornman

 

I think that will go right through a thin-walled alu bike as well. On my alu waterbottle cages the bottle has already abraded half-way through the cage itself' date=' and that is 6mm thick!

 

It is quite weird, but a soft water bottle with grit, will abrade a harder surface with no damage to the water bottle. I see this in Rox poplocks uite often, where an aluminium shaft moves in a nylong bush. The nylon remains perfect and the aluminium suffers.

The fact that the water bottle (polyethylene) is quite flexible and that the material is actually quite soft means the grit digs into the water bottle which then acts as an abrasive.  I found this whole thread quite illuminating (I have seen similar damage on Alu frames, both road and MTB), but JB's comment on the apparent lack of damage to the water bottle really caught my attention.  I just checked the water bottle (old) on my MTB parked in my office and you can quite clearly see pits and short, deep scratches on the surface of the bottle (bottom third of the bottle)  HomerSimpson2010-02-12 05:05:15

JB why don't you save your gratuitous comments for your coffee club? Bad design and testing? Recall products? Rubbish? Puhleeez!

Were the right bottles used to match the cages? Probably not .... But hey, this won't stop you spewing your opinion.

 

In cases like this it is typically an arbitrary bottle without the correct profile for the cage that gets bounced out and slides down to cause the damage.

Oooooh..... I reckon a large instruction manual is then needed and little pictures on the cage of what profile bottle needs to be used.

I had a Cannondale in here yesterday for a wheel issue. I immediately noted his Specialized bottle cages as well as the same carbon damage. The owner didn't even know.

 

I think Specialized screwed up here and should recall the product.

 

The local distributor should take the initiative and take all the unsold cages off the shelves and send it all back to the US.

 

I had the same rub with no name carbon cages.

 

The specialized cages have some degree of adjustability, were they elevated as far as they could go? or just plonked in?

 

I am aware of this problem and have seen it occur from a few different cages. I now test my bottles and make sure I have the cages mounted as high up as they can go.

I didn't pay attention to where they were locked into their slots but that won't make a difference.

 

I think you have the wrong mental picture of what happens. In this case, the bottle on the seat tube, slipped past the little lip at the bottom of the cage and the bottle's one bottom edge rubbed against the downtube.  Adjusting this cage (or its mate on the other tube) won't make a difference other than a 5mm higher or lower rubbing spot.

 

If I understant you correctly, you say the higher they're mounted, the less the chance of the bottle reaching the opposite tube. The problem will then be exaggerated with a smaller frame.

 

I think the cages are rubbish. Period. Jules, Epoh, how do you feel about the cages costing you money and angst? Would you buy them again?

wait wait wait, let me guess, the brand in question produces a special bottle with Bruin technology that prevents the bottle from flexing open the cage and dropping past the lips right, am I right, am i right

 

I've seen these cages and many shop owners try to porn them to me but any bottle cage thats that flexible or is has tension provided an elastic band belongs on a kiddies bike...

 

Oh I get it, the cages can only accomodate kiddies bottles.

why didn't you say sooooo

Yeah, you must be correct, most of us ride with arbitrary bottles that are totally unsuitable for our cages. I personally use an old 500ml coke bottle I found at a plastic recycling dump. Had it for years. At first it did give me a lot of problems, bouncing out continually and slipping down onto my frame likes Jules' did. Finally after years of turning around to pick this bloody thing up from the road all the time I got gatvol and modified my stock standard bottle cage with some old coat hanger wire. Now I have no problems with my bottle falling out at all. Jules, I can help you any any other person who has the same issue and show you my modification because I know how fond you are of those banana sterie dumpy bottles that you like to use for races!

Why don't you go and look at the lip on the bottom of a Spec cage? Or is that beyond your need to try and be facetious? Then tell me the lip is too small. For all the little JB acolytes I'll repeat - with a Spec bottle this problem is absent.

But then, this is THE HUB so me the fool for expecting different.

Dear Cyclequip. Welcome to the Hub. I'm sure we're going to learn a lot from you. My acolytes and I look forward to further lessons.

 

Lefty, Jules, Epoh and the chap with the red Cannondale with the hole in the down tube....you're a bunch of poepols. I told you to stop using those stupid bottles of yours but no, you insisted and now your'e wining about holes in your bikes.

 

 

 

These bottles of yours are just no good. Military olive is so butch and so yesterday. Besides, any self-respecting acolyte can see that it will not fit well in this cage.

 

 

You need this bottle. It is no ordinary bottle sommer just  picked up as a freebie at the race entry table. No, it has a meshing interlocking bottom curve and thus cannot escape through the bottom of the said cage.

 

 

 

 

 Get with the program boys. No more pink drinks from incompatible botles. I'm watching you.

What an arrogant reply from an even bigger arrogant arse representing an enormously arrogant bicycle company...

Replies like that that will not endear your company or it?s inferior products to the buying public.

Hey Arse, I took a look at the lip, and let me tell you? THE LIP IS TOO SMALL

Maybe if you look at it, it might look big enough, but then again, it?s a common mental enlargement phenomenon with people whose egos are much larger than their? ehmm... brains?

What a D1ck!!!

[Beebster]

HAHAHAHAHAHAAAAAAAA LMFAO!!!!! Nice one JB 

[Minion]

 

 

 

Hmmmm. It looks a lot like this one:

I guess those subtle changes in slope at the bottom make all the difference.

 

 

 

 

[GoLefty!!]

Yes it creates a perfectly interlocking system called InterH2OLock, Specialized has patented this technology.

So now you can only use a specialised cage with a specialised bottle.

Facetious

1. not meant to be taken seriously or literally

2. amusing humorous

3.lacking serious intent; concerned with something nonessential, amusing or frivolous

 

Thank you for improving my English vocabulary. 

 I had a look at the lip again and it still appears to be too small. I do need JB to see this.
