you say you've got the b screw tweaked "almost" all the way in, why not "all" the way in? also, see if you can flip it around backwards.

With the screw tweaked almost to maximum, the upper pulley does not touch the 1st gear, but I still can hear a grinding/roaring. And this is while the bike is on the pedro. So I can imagine it will be worst when going uphill.
The vibration stops in second gear (28T)
I'm asking myself, should I keep the 11-32 and buy a mountain derailleur or should I simply buy a road cassette 11-28?
To those who feed this forum, thanks for your insight/support/testing

Ok, I have reversed the screw as advised by Motobecane. It sits better now.
Still no contact in first gear but when i spin the cranks the chain jumps every 2 rotations.
When in 20th gear, it stutters 5times per rotation.

At first I thought the link pin on the new chain was not inserted enough, but it's flush.
I could post a video, but it would be made with $hitty phone lens
FWIW. Sight unseen ([COLOR= #808080]which is to say that I may not be correctly picturing what you are describing[/COLOR]), let me note that the individual teeth on cogs can get bent ... separate cogs which are not attached to a spider can be "warped"/bent, too ...Originally Posted by digifant .
When on smallest (10th) gear, the chain always rubs this one tooth (shaped to facilitate downshifting) on the 9th gear.
I describe the tooth as wide towards the back of the bike and thinner towards the front.
It's almost flat towards the chainstay but notched/sloped towards the hub.
Hi digifant, perhaps the dÃ©railleur hanger is bent inwards a little? The RD and cassette are brand new, aren't they? Is your crankset square taper? Actually, I think we need a photo ... and it is nice to have a good bike mechanic to helpdigifant said:No, i'm using the small gear (rear) with the big ring in front.
cranks are regular sram with q-rings (40 & 46teeth)
It's wearing out my patience, and probably yours too, so i'm about to take it to the shop.
I don't see it but derailleur might be bent?
