Rehab Redux- Moots Routt project

[Ron]

BTW- here's what a wide internal (25mm) and external (31mm) rim does for a 32mm tire (which is sitting at 35mm now). Awesome profile that makes this tire almost aero

LOL, I'm not a big Shimano fan but it would be nice to run a 48/32 with 11-32. which I can with Absolute black CR's

If there's only one thing that Shimano makes better than anyone else, it's cranks.

seriously X2. Even as someone partial to SRAM stuff their cranks are great. I hate the idea of carbon cranks on a MTB due to rock strikes and SLX cranks are silly light and fairly cheap.

 

[Philpug]

I am much more of a Shimano fan when it comes to MTB shifters.

hey looking for some collective wisdom here. I was going to move over my etap red from the roadie but the cost of AXS is just too much. close to 3K. So, the one thing that really bothers me is the amount of throw required to shift on the Ultegra. It also doesn't really shift as precise as I would like. I would also like to shed a few grams along the way. So, I was thinking:

1- put a new sram 1190 11-32 cassette. says about 70 + grams and I like that cassette
2- Dura Ace shifters, reduced throw and a pretty good savings in weight
3- dura ace front derailleur - def' an improvement over the 6800 Ultegra
4- I have 6800 cranks, so not sure if I should keep this and run Absolute Black oval 48-32 rings. the other option is to go to DA cranks and Absolute Black CR's. Not sure the extra money here is worthwhile.

Altogether, that's under 1K, should save me about 300 grams and improve shifting

THOUGHTS, SUGGESTIONS?

 

[Erik Timmerman]

Have you ridden the newest DA? I haven't, so I don't have a valid opinion on that. That book looks pretty dialed. Maybe I'd change the chainrings to the ovals, but personally I wonder if they could ever shift as well as Shimano rings do. I love ovals, but I'm running them on a MTB with no front shifting.

I'd check with @Living Proof because he will probably be buying it soon.

What about the new GRX in Di2?

 

[Ron]

What about the new GRX in Di2?

Honestly, I'm not sure of where Shimano is going with that. Its ridiculously heavy. You can do the same with Ultegra di2 and use Absolute Back or Wolf tooth CR's. I am not a di2 fan due to the battery and overly complicated junction boxes and such. I love Etap because its so simply and streamlined. No shifter cables, no junction boxes or hidden batteries. Other than 2 different ways to shift (yes, I do have to remember every time I switch bikes) I would be fine with mechanical.

No, I haven't but the shop boys agree its dialed this time. short throws and very crisp shifting. I don't need a whole new groupo (it already has Ultegra discs) so replacing the key components would be easy. I think it would be a solid choice.

@Philpug LOL, no, Living proof is not getting the moots. Its a frame that is near perfect for me, other than the external routing, (which has advantages) I have zero complaints about the bike. I put together a spreadsheet of a few different gravel bikes and the moots is so similar in the key geometry to my Emonda. other than a taller stack (which just means fewer spacers) and a more sack head; which you want on a gravel bike the other dims are almost exact. And, if you haven't ridden a Ti frame with bigger tires, you need to. It's damn close to riding on a cloud.

 

[Erik Timmerman]

Ron the only problem I have ever had with Dura-Ace is that it will never wear out and you will have no excuse to upgrade.

 

[Ron]

I like that.

 

[Ron]

so, it looks like I should buy:

I think replacing these are worthwhile from a weight standpoint and certainly much improved shifting. Not sure if there's a real difference in braking but it appears I cant buy the shifters alone.

9120 shifters with new brake calipers. I am doing some research but it appears the shifters have to be paired with the new calipers?? I can't find info on the 9100 shifters which are sold as stand alones. Not sure if they work with Discs. my calipers are fine, I dont see any need to change those. The 9120's are only sold as Flat mounts. I need a post mount and from what I can tell, there aren't any adaptors for a post to flat (and 140 to 160 rotors)

If anyone can confirm that 9100 shifters will work with my Shimano calipers please let me know


9100 Front Derailleur -


not sure:
CRANK: Cranks are expensive, $400, I wonder if the better option is to just run the Ultegra crank and replace the CR"s with Black ovals. Going DA will save decent amount of weight but not sure if it's worth it if I go 46/32t on either

Rear derailleur; this doesn't seem like a worthwhile upgrade from the 6800. I understand you can run a 32 on it but I dont think there's any real gains.

Thoughts on the crank? Is there a better crank to take a look at? I'll change out the cables as well.


Thanks for the help

 

[Erik Timmerman]

You know what that bike needs? Orange Hope calipers and rotors.

 

[Ron]

I think there's enough orange on the bike

 

[Ron]

so after doing a few hours of research it appears that I can't run Shimano due to my frame having post mount discs... I'm back to axs.

 

[Erik Timmerman]

What do you mean, can't run Shimano? Aren't you running it now?

 

[Erik Timmerman]

Hmm... looks like current DA brakes are flat mount only, so get loose 9210 shifters and either run your Ultra calipers, or get these:

I'll check into that. thanks. I didnt see the shifters sold without the calipers but I'm sure they do. I did see 9100 shifters but there wasn't any indication if they worked with Disc or only rim.

can't run Ultegra with the 9100 series; incompatible.

 

[Erik Timmerman]

I haven't seen anything about compatibility between DA and Ultegra. If the slave cylinders are the same diameter and they both use mineral oil, I don't see how they'd be incompatible. Here's a little bit from Zinn on the subject.

It appears that there are differences in cable pull on some of the cable brakes, so maybe that's where some of the confusion comes from?
