sprockets
« on: November 18, 2007, 06:33:28 PM »
HI i've got the ecoflat pro crankset ind im wondering which sprocket to get the 20T or the 18T.i like the 18T becouse the gearing would be lighter with my 9t driver.is 20T stronger than 18T ?not sure if the 18T could brake easily.....becouse some of my friends had 20T ninja and they've broke em all

The 20t will be stronger than the 18t but you should be more concerned about how it will feel... 18/9 is really light but if you like it than ok!

Not good, i ride 24/12 and thats still a litte slow.
I think 26/12 will be perfect.

Yes it does, thats why i'm riding a 24t sprocket... its the standerd sprocket that comes with the Ecoflat pro.

The current ecoflat crankset is euro bb. It will not fit U.S. bb. The 2008 ecoflats come in all bb configerations. 20/12 will not feel right. If you want 20 up front, the ecoflats have that size but you really need a 9 tooth freecoaster.

Ha ha!
Guys, guys, guys.
I'm really disappointed!
The smaller the stronger.
No, a 20T sprocket isn't stronger than an 18T sprocket!


I disagree with you Yeti,
If we are talking about the same sprocket in 2 sizes (same design and material)
I think that the bigger (more material) the stronger it will be.

In this case we are talking about only 2 teeth, that doesnt make a big diference.
The design looks strong and the weight diference is only 6gr.

NEW 18T = 0,84 o.z. - 24 grammes
20T = 1,05 o.z. - 30 grammes
5 mm thick
7075-T6 alloy

You can't run small gear technology with U.S. BB!!
20T, 18T, 16T, 14T works only with Euro BB or Spanish BB.
I guess 16T or 14T/8T works only with Euro.

Also you need a frame that's made for small gears.

thats funny, because i have  my dividual witch is a american b.b. and it has a 20t st martin  sproket on it.
i dont think though i could go any lower.
so under 20t would not work for a american b.b.!!



--------------------------------------------------------------------------------------------

but now i m curious of the mid?
is that not the same size as the american b.b.?- just press fit?

It's not about "thinking", it's about "knowing"!


How do you know that?
Have you tested the same sprocket in 2 sizes to say that the smaller one is stronger?

Alot of people broke KHE ninja 20T and 25T sprockets but I never heard of anyone that broke a bigger size ninja.
