is anyone still making 7075 stems?
« on: March 11, 2016, 05:39:33 PM »
I completly understand 6061 is affordable. When forged properly its plenty strong bla bla blah...

But my problem is that if feels rubbish during 1st installation. ALWAYS. Soft and potato like.
Newschool design with shorter and shorter bolts arereally too short for 6061 (threads will die sooner or later).
Then BAM BAM BAM  threads are really dying too fast. even w/o overtigtening.
6061 stems are for 50kgs kids ONLY. Terrible!

Who is still making solid 7075 topload stems?

Pretty sure the Eclat Burns stem is 7075.

Wasn't the consensus that 7075 was too sniff leaving it prone for snappage instead of bending like 6061. With that being said the Primo Aneyerlator is the only stem I know of that's still 7075.

"...For Sean, we created a fully CNC machined 6061-T6 ..."

few years ago most good stems were 7075.
Some cracked becasue of poor design.

A big bulky stem is probably a good thing if you're fucking stems up. 7000 series isn't going to make something unfuckable.

Stems are a pain.

With the high bars people run now it is asking a hell of a lot for any stem to clamp the bars properly without crushing the clamp area. If you use 7075 then the extra hardness (and its a lot) makes it harder for the knurling to bite in, so you need more pressure to get the same kind of grip... having said that, the extra strength means that a 7075 stem is less likely to slip IF you can get the tension just right so that it doesn't crush the bar and isn't too gentle so the bars slip and chew it out before you get that far. I think that 6061 is a "safer" bet for most riders and will get the necessary grip more easily without the rider going too far and crushing the bars.

Tree may do their collet stem in 7075 (if they still make it?)

Had the last Standard top load Stem and it's pinching.
Now on a Life Free Flyer and it won't be pinching anytime soon.
6061 on both
Had a Superstar Elect too 7075 it sadly pinched.
Turtleneck look awesome but much too long.
