eeesickle - 500w Cyclone (Warning: Pic Overload)

[Miles]

I think it just confuses things.

Not sure how providing more knowledge, specific to why a component is more superior, would be more confusing?

Always open to better explanations. More than happy to hear another take on the difference between ratchet and sprag bearings.

Great. So why is a sprag clutch superior through having more sprags than a ratchet freewheel has pawls, then? As I understand, it's just a necessity stemming from the lack of positive engagement. I certainly agree that the sprag clutch has advantages...

Now Miles, that would hardly be fair, as you are the one to state pawl count had no relevance to Torque. So I would like to kick back tonight enjoy a beer and be further educated.

Yeah, but it would be better not have to replace with after market item to start with

Again ill ask...how many Eno freewheels have you heard about failing?

One more than Sprags

As you were the one making the initial claim, it's up to you to justify it. The two systems work in different ways, that's why the pawl/sprag counts are different.

Actually Miles, I just made a comment relating to an early post here.

Elation use a different type of freewheel crank setup.

Then a comment was made by others about Torque. Then YOU drew an inference between the two comments.

If you have an answer, then please share it. You are the one who stated that pawl count had no relevance to Torque, not me. So OK, please explain so we can all understand your line of thought.

Cheers

PS. English is my second language so will be much better coming from you.

Would it be possible to move the last 12 posts to a new "ratchet pawl vs sprag-clutch" thread?

Alan, you have been open about being a vendor for Elation products (a competitor of Cyclone), but I feel it is inappropriate for you to post in this thread (just my opinion). Unless, of course, Elation has started selling the bottom-bracket sprag-clutches by them selves, and you are offering eeesickle advice on a replacement bottom-bracket freewheel when the stock Cyclone wears out (rather than the replacement upgrade ENO).

You might not realise your postings in this thread can be misunderstood by some as being rude, to paraphrase..."Your build isn't bad, but Elation is better". If I am wrong, and you are selling the sprag-clutch by itself to Cyclone owners, what is the price?

Ratchet system has positive engagement, so the load can be taken as close to tangentially as is practical. The sprag system relies on friction and there are more radial forces, which is why the specs for the sprag clutches state that the rating is dependant on housing, pre-load etc. If a sprag clutch had 3-4 sprags it wouldn't be very effective, unless it was massive I think this is why "spreading the load" is more important for a sprag clutch than a ratchet clutch.

Hi Miles

Now that wasn't so hard was it

Hey Spinning, might bow out. Too often I have tried to offer general info and gotten 'beaten down for it" or bagged. It is not worth the hassle each time I try to offer info.

Boostjuice made an observation about the elation crank, I responded. No commercials, just pointed out a fact.

I have made a number of purely theory posts in the past to try and help others understand systems, but in EVERY instance I get challenged with very little substance coming back. But perish the thought when I raise a challenge.

Will go back to answering emails as I get them. Info may not be widely disseminated, but at least it gets appreciated.

Chow All

PS. Am sure though I will continue to get emails from people wanting to upgrade their failed Cyclone parts though.

 

[Miles]

Your turn, to explain why a sprag clutch is more robust?

I respect your commitment to produce a higher quality product than the Cyclone - that's not at issue...

Hey Randal


how's the bike going? I finally finished mine, second run today.

How is your battery life? I've used my bike mainly uphill and battery alarm seems to come on pretty quickly.

I'm getting a bit of drag with the freewheel on my Cyclone 3 wheel kit. When you pedal backwards you can feel quite a bit of resistance.

It's very free for the first couple of pedal backwards cycles but about the 3rd cycle I can feel resistance...enough to affect the amount of power to the wheel maybe?

Maybe I have over tightened my crank?

Nice pics on Op's thread though.
