Snapped spindle

[silva]

Before or after you filed the teeth down?

That was on my current avatar bicycle (a ring mounted since 2019, with a quarter of its teeth broken off), not my previous bicycle.
But you don't Really Follow Things eh Mister classic33?
That's why you contradict yourself - it's outside your scope.

I give you a Copy Cat of the Answer:

About your new Nth point of criticism here: you equal my description "alot of play" as neglection, but for my case, singlespeed, chainring 52T on the previous bike, the clearance the chainring had with the frame tube, was barely a mm away.
That is, at the edge, the top of the teeth of the chainring.
So, any play is already "alot", since the chainring would start to fret in the alu of the frames tube.
I noticed paint damage, that's how I discovered it.

Silly question then.

Why the hell did you fit a chainring that was that close to the frame to start with. That is plain stupid. You either need a longer BB axel, or a smaller chain ring. It's just going to cause issues. It's like people who fit too wide tyres then realise when the chainstay has worn or there is no paint left on the fork crown as dirt has worn it away as there isn't sufficient clearance, and also tyres/wheels flex.

Proof if ever it were needed - the hammer and chisel are wonder tools.

Your post reads alike you drove a lawnmower over it before clicking "Post reply".
Can you retry, please?

Here in lies your extensive issues. Piss poor maintenance.

 

[fossyant]

I replace chainrings if they are showing signs of wear. Drop a chain when sprinting or climbing and you are likely in need of a trip to A&E. OK, that bike you have isn't going to be going fast, but I take absolutely no chances with my FIVE bikes. All are maintained and looked after. Dropping a chain or snapping one in traffic can be deadly.

Your maintenance regime and trying to eek life out of components way beyond their service life is a big mistake. It has bitten you a few times with, what I would call, silly mistakes and failures.

No silly but good question, I didn't fit it, the dealer of that previous bike did it.
On the other (square taper), the first of two bicycles I bought from him, I much later on discovered he had inserted small roundels between the chainring bolts and spider, in order to achieve "some" clearance. But those bearings never failed, so it wasn't discovered before.

The dealer of my current avatar bicycle also started with botched jobs, the first discovered was similar and just weeks after purchase: alot play, chainring teeth cut in frame.
In the communication he diagnosed it as failed bearings.
In his shop it turned out they didn't, he said it "just" had "come loose", and said he'd put loctite on it to avoid it reoccuring.
Read: a botched job from start.

Much later on, with my current / avatar bike, I discovered a similar botched job, also already mentioned here, 7 years after purchase I discovered the dealer had chosen a spindle that was 5 mm longer than was needed, explaining the increased pedal strike risk, and also proving that he could have had the 5 mm wrong chainline correct by just chosing a 5 mm shorter axle. I didn't know at the time, so I messed around with 5 mm Velosolo spacers during all the years.

What made me discover it was the broken frame replacement, at which I decided to move back from the flawed Octalink 1 test (to eliminate the chain tension variation) to square taper.
The dealer of my previous 2 bikes, that mounted the Octalink crankset, was on its package box labeled as 5 mm shorter, which I noticed. Confirmation came with the chainline, with the spacers, was again wrong.

So, I intervened at the dealer of my current avatar bike, when he wanted to again mount an axle of the length as before.
An employee of him (not there back then at bicycle purchase time) started to measure, and said I was right.

So maybe you can start to understand my current attitude towards dealers, why I went fixedgear, with bolt on cog, as it allows me to do all regular wear replacements myself.
DIY = do it good, or face consequenses yourself.

That's piss poor totally wrong - the contrary: my chainring now lasts 7 years, with 3 of those with a quarter of its teeth broken off.
Same for the rear cog, the one mounted NOW, is the same one that was mounted in 2017 at bicycles purchase time.
I had replaced it due to teeth worn short, risking breaking.
At a later mounted cog, I decided to allow a break to happen, to see what it gives. It didn't cause a problem. Then 2. Didn't cause a problem. Yet, at 2 I decided to not risk further, and replaced.
When that ones time was worn up by the chain then, I decided to walk further on that perceived path of risk.
I allowed 3, and in the end, even ALL 16 teeth to break.
I'm now riding almost a year with it.
The drivetrain does the job as before.
The only problem was clearance: the chain links void the circumference of the bolt heads of the 16T cog. Since half a year I keep an eye on it, and Good News: the voiding ceases to increase.
Since the 6 bolt heads now have a little flat section on their circumference, upon unmount>remount, I lay them on a marked paper as to make sure that the same bolt goes in the same threaded hole, so that the flattened section stays oriented towards the "teeth".

 

[fossyant]

Well, your 'dealer'/ bike shop owner is an idiot(s). I would suggest you do these jobs yourself. I never take my bikes to a bike shop as I do a better job and take care. You also need to pay attention to the bike a bit more.

Says it right there. Poor maintenance. Very poor maintenance. 7 years, of which 3 of those years it's missing teeth. Says you should have changed at the point one tooth snaps off, and if you were maintaining the bike, you'd have spotted the wear a year earlier. You are kidding yourself. There is no-way I'm riding a bike so badly maintained with the wear you are describing.

 

[fossyant]

There is no badge of honour making a chainring last 7 years you know. How much do they cost ? My commuter bike, I go through a chainring every 12 months, and a chain and a cassette. Total cost is about £70, once a year. I can tell when the chain ring is wearing, the shifting isn't as good, and the chain is quite slack when you pull it at the 'two o'clock' position. It also doesn't run as silky smooth. I could leave it on for longer, but I'm not risking an accident.

That £70 is recovered in just 7 days of riding. It costs me £10 a day to drive to work and park.

You mean, my piss poor funding of bicycle industry and dealers?
My drivetrain continued and continues to do the job, despite the broken off teeth. In case ring, the remaining teeth suffice, in case rear cog, the remaining valleys suffice. And bonus: the thickness of the metal is there the max = the thickness of the plate where the teeth were machined out of it to high and narrower.

Have you ever fitted Hollowtech 2 yourself?

J.P. Morgan disagree with you on the weight.
Their confirmed weight 28.35 grams is heavier.

You have the required $10,000,000 in your account with them, to be even considered for one?

Still suggest you read all of what was posted in #230. Then answer the question you were asked in that same post.
