Hello all,

I was wondering if anyone had success using one of these with a 5 speed 14-28 freewheel ? 14-17-20-24-28t cogs Using Simplex Criterium RD Research suggests the RD should reach to a 28 without assistance but It won't work for some reason. I have one delivering tomorrow but any suggestions would be grateful.

Thanks,
Doug

I currently use one with a shimano short cage dr and a 14/34 5 speed freewheel. It works fine and I've also used it on a six speed 14/34 as well.

Ok, thanks. You give me hope.

Should work. They like steel.

They're great, but remember that while they let you use a bigger small cog, they don't increase your derailleur total capacity at all.

I assume you meant a bigger big cog? I bought one to use with a 11-40T (1x9) cassette, but I plan to use a long cage RD.

jonwvara 

Yes, a bigger big cog. I have a surprisingly hard time distinguishing between big and small sometimes. I think I have cog dyslexia.

I consider every Roadlink I use to be a dice roll. RD wrap is the random variable.

RDs are generally engineered without a Roadlink in mind.

Totally kidding, of course.

I have been holding back for years! It's an engineering thing about proper descriptions. Cogs are in iGH hubs.

I retain and assign engineers.
I read the report conclusions.

Otherwise I tend to avoid conversations that need anything more than a "yes" or "no."

Not long ago, I hired one to interpret another's 302 page report. I asked for a yes or no, and still got his findings plus an unsolicited unqualified opinion that then rendered his "yes" moot.

They do generally understand what "just answer the ----ing question" means.

They know HOW things work. I just want things TO work. They make the world go around. I just ride it.

Yes, a freewheel cog is not a cog. It is clearly a sprocket.

As a former editor, that usage has always bothered me a little. But I try not to be that guy in the opera audience who yells "Brava!" when the soprano finishes the aria, meanwhile looking scornfully around at all the yahoos who are yelling "Bravo!"

But like most former editors, I all too often find myself being that guy whether I want to be or not. The life of the pedant is more about frustration than satisfaction

As long as we are being pedantic, I object to that definition of sprocket. That is the description of a sprocket tooth, not a sprocket. Elsewhere (wikipedia, for example) points out that a tooth on a sprocket is also called a cog so that description meets the meaning of cog. And, besides that, as long as we're being pedantic, it should be "each [...] engages with the links of a chain[...]"

But, people call sprockets cogs and sometimes it sounds/feels better to write sentences in which the subject and verb do not agree in number. Just the other day I learned that in today's world, the proper singular of dice is dice. I'll get over it.

Many years ago I was informed of "Skit's law" which states that it is nearly impossible to identify and point out a minor mistake in writing or usage without making at least a minor mistake while doing it. Usually I obey Skit's law, no matter how I try to avoid it.

jonwvara 

Skit's Law! I like that!

There are some English words that have no plural. Sash, in the context of a window sash, is one, I believe. You can have one sash, or ten thousand sash. But you can't have two sashes.

I'm reasonably sure that I have just violated Skit's Law.

More pedantry, a cog is a tooth on a cogwheel (sometimes shortened to cog), which is a gearwheel consisting of cogs (teeth) that are historically separate pieces inserted into the wheel. The word sprocket does in fact historically refer to the teeth, but is also an abbreviated term from sprocketwheel. One could make an argument than some of the earliest implementations (far predating the bicycle) of sprockets in fact used cogs as they were understood at the time.

In terms of the actual subject in question, I have to wonder how much it will degrade shifting in smaller cogs (as understood in the bicycle world to mean sprocketwheels driving the rear wheel).

I wonder if George Jetson knew the difference?

He rode a Y-Foil, but I’m sure he wanted an Ironman.

If a C&Ver ever has a chance to visit New Hampshire, make an effort to visit this attraction; The Mount Washington Sprocket Railway. It is fascinating to see in action.

BTW, based on this thread, I ordered a Wolf Tooth with the hope it will work on a Dura Ace AX (spec'd at 12-26 teeth range) and allow me to run a 30T sprocketwheel (or is it a cogwheel ) as my new low gear.

Up until my comment , post 12, I have referred to the "cluster" as a "block" to avoid using "cog set" or "sprocket set"! Several years ago, someone on BF pointed out the difference. I looked it up and was converted. Like many who are converted, in other ways, criticism and difference of opinion is inevitable.
For me, it makes a difference as the mental model pops into my head based on the context and words used. I am not perfect by any means. It just works for me. I really don't care what others call an item, it is the message that counts. Yeah, I do believe in freedom, and the right to be right and wrong.

Until the engines largely switched from soft coal to diesel a few years ago, you could see a plume of black smoke on the side of the mountain from the hill above my house when the weather was clear.

Technically, though, I think it should be called a "cog railway," since the central drive gear engages a stationary linear gear between the rails to push the train up the mountain--it shows nicely in the picture above. As a byproduct, it also create some coal smoke, since I think the company still runs one coal-fired train a day.
