Whenever I need a guide when working on my bike, this is the channel I first go to. Thanks!

If one Channel is really worth it on KZbin...it this one for sure👍.

Thanks for posting, my mech was rubbing on the biggest cog and realised I was in between the X2 mounting lugs and not on the bottom one

thanks for sharing. what about that hex screw right on the left side of the derailleur hanger screw? it has to be loose or tight? my derailleur is touching the frame and when i push down and tighten that screw, it works...but im not sure if this is the correct way...thanks

Does anybody know SHIMANO mechanical road 11s pull ratio is compatible with Shimano mechanical road 12s？If so GRX 12s Mechanical shifter can mixed UT8000/DA9000 RD and still use 12s road cassette.

[@FreeToCycle]

Yes works fine! I will have a video coming out to show you👍

[@alistairmacfadyen9365]

Brilliant, thank you so much, very informative

[@drscre]

What should be the length of the housing part between derailleur and frame port?

[@nalinjain7343]

Does the cable adjustment change the distance between the gaps of the shifts? Or is this constant because of how much the shifter pulls it?

Hello Author, My current is using R9200 cassette and new 12-speed 105 rear derailleur. No matter on the big or small chainring, the 15 Teeth cassette is still to make noise, when I fine-tuned the screw, just tighten it (15 Teeth) smoothly. But, the 21T and 23T will make strange noises May I know do you experience this issues on your side? Thank you very much!

Got a Canyon earlier this year with this groupset. It's been ticking on the largest sprockets. Just checked the B screw using the template that came with the derailleur and your guidance. It was way off - too high for even the 34, and I've got the 11-36.

Try the R7100 RD on a 11speed system EDIT: Not Working
