no issues....

[Mattias_Hellöre]

Thank you Eliflap, it feels good to me to know it works for another one than me.

[eliflap]

I just made one chainring with 2.2mm 6Al 6V 2.5Sn titanium at 2.2mm thickness.
From the beginning I drawn on 2mm as base so I was forced to lighten it a little more and make it look more like it was ME who did the chainring.

2mm is not silly thin when you think about the Sugino CSS chainrings is made of stamped 2mm aluminium.

Real world field testing soon, I think it should not be a problem.
3 times stronger than my stainless steel chainring who works perfectly good.

it is this one on my bike

[eliflap]

i received many negative comments ... except 2/3 guys

at first sight everyone tells TOO SKINNY , FALLS AFTER 1 KM

... however , i do not many km today but under rain and lot of mud and wet sand ...

[olzone]

I thought that was the model.. have been looking a bit at the edge 305 myself. Perhaps I should get it :-)

[Mattias_Hellöre]

All new design 44T, I haven´t received my sheet of titanium yet.
So it became in 2.0mm stainless steel instead.

86 grams in 2.0mm SS, should be sub 50 grams in 1.8mm 6al4v.

[rockyuphill]

good grief you're almost making stainless steel lace doilies...

[ryball]

holy baby jebsus that thing is like a g-string for your cranks.

Should I take it positively?

[ryball]

Should I take it positively?

Yes, but only if your cranks are girls.

[Mattias_Hellöre]

What about these?

[NoValidTitle]

That 44t is insane!! I hope it holds. Great job.

[eliflap]

ah ah ... finally see as real work...

good .. but on a bike maybe is a strange design ...

[Mattias_Hellöre]

I will mount it on my Zaskar tonight and take a picture.
So you allcan say if it´s pretty or ugly.

I don´t care so much when it´s light.

I´ve seen uglier rings, like FSA aerodynamic.

I think it looks awesome.

any plans for 4-bolt 32t SS rings?i want one. you know you could get all of boone's business now that they are slackers.

[Mattias_Hellöre]

Actually, I can do anything as long that´s a sheet because I´m a operator for a water jet cutting machine and unlimited access of stainless steel.

Titanium is harder to get because skyhigh prices.

Boone is a upper class product I think, very beautiful rings but they are busy.

so what would you charge for a steel SS ring,4-bolt 32t. just ball park is fine.

[icemonkey]

You do beautiful work! Art, function and flair. You have inspired me. Thank you
