(Clearly Un)Notable Wheel Differences

[lazyfatgit]

I'm afraid you are bullshitting yourself and I would imagine quite a few gullible others too.

Stiffness. The amount of deflection in a wheel is in the order of 0.05mm. That's approximately the thickness of a piece of printer paper. Let's say the one wheel is twice as stiff as the other wheel. It means you can feel, through the frame, deflection of 0.1mm. Dream on. I don't know how you managed to compare umps from wheel to wheel.

Responsive: What does that even mean? Can you define it in any way?

Steered quicker. Steering on a bicycle is initiated by lean and thereafter by torque through the steerer. On the same bike, this will be, well, the same. unlike cars which have a slip angle in the tyre, bicycles and motorcycles don't, so I don't know where the extra steering speed comes from. As for cornering on rails, that's just magazine speak. Unless you can define it, it is nonsense.

Go for a ride, take photos and drink a beer.

By stiffness if you mean how much a rim deflects in towards the hub you may be correct. However I've had wheels where the spokes must have been made from spaghetti with the amount of sideways deflection and brake rub.

Only my view, but i notice a greater difference with tyres than different wheels on a bike. If i go out on a club cycle with touring tyres fitted then every one else seems to be just that bit faster and harder to keep up with, go out on a bike with reasonable road tyres and suddenly same cycle with same friends and same bike everyone seems to be cycling slow?

As for differences with different wheels perhaps just me but i dont really notice much difference apart from with deep section wheels when cycling when windy and tbh not a good difference.

I actually take an interest in some of the discussions as it can be interesting the nuances implied by the grammar and punctuation used.
I find writing takes some thought to try and put a point across in the way that I'd convey face to face with intonation and expression.
Never really ever set out to offend anyone.

None of the wheels in question fall within that category. You are describing faulty wheels. The OP didn't describe any of the symptoms you mention.

OK.

As a matter of interest what would be the acceptable limit for deflection (in any direction) in a well built wheel be?

Since the deflection in the materials used on wheels is elastic and not damped, most energy used for the deflection is returned.I.e. energy is not lost.
Acceptable deflection would thus be anything that doesn't affect the wheel's function. It should not cause brake or frame rub and not affect stability.
There is so little demand for lateral stiffness in wheels that the structure can be built with spoke bracing angles of as low as 4 degrees (right rear) and which then only occasionally rub with dual pivot brakes which have a clearance of approximately 1mm only.

It isn't an issue.

But if you do, so be it.

Indeed.

I made a flippant and ill conceived remark and I'll need to live with it.

I had a break from this forum, due to a few plonkers, who know better. A year or so later, same plonkers.

Apologies for wasting your time and mine.

Surely the correct way to respond to something you might take issue with is to question it, put forward an alternative view and then debate it? Another alternative is to call 'plonker' and walk away. For the record, I don't see anyone being a 'plonker' on this thread...

I tried that last year and don't want to argue about trivial things, that people think about my experiences, again this year. It takes away the enjoyment, so am walking away completely.

I take back the plonker comment, as not trying to troll. (Wasn't aimed at you anyway, if that matters.)

EDIT: Actually, I don't take back the Plonker remark, after being labelled as a Bullshitter prior to that and since.

Surely as this is a cycling forum you should be riding away completely.

LOl, either that or cycle fast for a bit and wait at the coffee stop for everyone to catch up again.

I have just bought a set of £249 advertised at 1480g the set came in a smidge over 1500. I cannot tell the difference between these and the £700 Fulcrum Ceramic Zero's.

In fact the £250 are better because at least they have standard spokes and a sealed bearing. Cheapest wheel I have ever bought. Of course I will reserve judgement until they have done a few thousand miles.

What really cheeses me off with Fulcrum is that hey sell wheelsets. I am really heavy on my rear rims so I have a selection of fronts!

Dear BP, just before you flounce, some observations. If, as a long-standing member of a forum you don't pay attention to long intense discussions where some members go to great length to explain things and back it up with scientific proof, and you then come and make flippant "observations" without proof, you will be rebuked. This will happen on any forum. Even if you don't participate in such discussions, you would have noticed them. Further, you could have done a small search on here to see if your observations and their conclusions haven't been made here before, by someone with reasonable knowledge in that area. That would have saved face.
Alternatively, just ask a question without making any pre-, no-one I've seen on here will zap you when you ask.
Have another look at your opening post and notice how it ticks off every "do not" box on any forum's To notDo list.
Come back soon. There is much wisdom here among the occasional barb.
