9070 vs 9150 di2 comparison
Moderator: robbosmans
So having recently upgraded a bike from 6800 di2 to 9070 di2 with no appreciable difference. I can't honestly imagine that the new dura ace is twice as good as the 9070. Given that you can get the whole groupset for what about a grand?

I tried the 8050 groupset a few months ago, i liked the way the shifters clicked over the previous generation. It can sound like a small difference but it made the group feel more genuine. I suppose they also changed that on the 9150?
Not sure about a lot better. There are definitely slight improvements that people may or may not care about or prioritize: lever slightly narrower, less pronounced bend on the hoods, buttons more tactile, ~8g lighter. Not sure that's worth over double the amount you can get the 9070 shifters forBdaGhisallo wrote: ↑Mon Sep 03, 2018 3:20 pmI wouldn't worry too much about which RD and FD you go with - both work very well and will do fine with 28T max cassettes. What I would do is to be sure you get the 9150 STI. The ergomomics of the new 9100 gen shifters are a lot better than the 9070 iteration, imo.

For me they are. Didn't like the dip in the top of the 9070 lever bodies. I was using 6770 STI with my 9070 setup until the 9150 levers became available.bilwit wrote: ↑Mon Sep 03, 2018 6:37 pmNot sure about a lot better.

Additionally, the improved tactile feedback of the 9150-8050 shift buttons is also a very worthwhile improvement.
Thanks for the replies so far. After doing a bit of research and reading online it semis 9150 is a bit noisy even when perfectly setup, whereas the previous gen is basically silent.
I also prefer the silver of previous gen, plus as mentioned it's about 800$ cheaper (around 1400$ at Merlin. I might go with that.

I don't agree with one being noisier than the other. To me there is no change, both are quite. I changed from 9070 to 9150 as I actually didn't like the silver accents, but that's personal preference. Agree if budget is limited then there are good deals on the 9070.

I've seen some postings somewhere about 9150 being a bit louder but it doesn't really make sense to me as to why so I'm inclined to think it's probably set up issues. It's normally the cassette that would generate extra noise and that hasn't changed design. You won't go wrong with either, both great group sets. I do like the way the shadow derauiler sits inline on 9150 though, but whether that's worth $800 is definitely debatable...caballero wrote: ↑Tue Sep 04, 2018 4:35 amThanks for the replies so far.

For the noise, there is no difference in my opinion. I can't tell the difference at all. I use the squirt lube in summer and purple lube in winter, no noise on both

My LBS mechanic swears that the 9150 RD performance is not as snappy as the 9070 RD and that it is a consistent customer comment. The assumption is that the longer cage on the 9150 RD does what longer cage derailleurs tend to do, i.e. shift a little slower. Even if this is the case, and I have no reason not to believe that it is, I wonder if a 9150 RD with the CeramicSpeed OSPW would shift about the same (or perhaps better) than a 9070 RD with OSPW. i.e. by using the same (OK almost the same) rear cage.
All of this does make me wonder why CeramicSpeed had to go with 13/19 pulley wheels on the 9150 OSPW rather than the 17/17 pulleys on the 9070 OSPW. Was it just so that the 9150 OSPW would work with a 30T cog or was it to improve the 9150 RD shifting performance?

Cage length has zero effect on shifting speed. Distance between the sprocket & the top jockey wheel is the main factor.refthimos wrote:My LBS mechanic swears that the 9150 RD performance is not as snappy as the 9070 RD and that it is a consistent customer comment.

Probably more to do with how the mech sits in relation to the cassette. To clear the cassette the mech would have to be rolled down using the B-tension screw. Even snake oil salesmen have to sometimes follow logic.All of this does make me wonder why CeramicSpeed had to go with 13/19 pulley wheels on the 9150 OSPW rather than the 17/17 pulleys on the 9070 OSPW.
