105 conundrum
So I have run into a roadblock here. I want to set my vaya up with a 105 groupset, but I want to keep cable actuated discs. 105 disc groupset is hydraulic. Will the 105 rim levers work with my cable discs?

That would depend on which cable disc brake callipers you currently have and which levers you are currently using with them. Current 105 brake levers have less mechanical advantage than ones from a few generations back. We know what bike you have, but not how it is equipped

Question: Why do you want cable discs? Shimano hydraulics are the best of the best - dead simple setup and zero maintenance, and they stop better than anything else I've tried.

Hydraulic won't work with cable discs, and as per Wilfred, why would you want to have mechanical discs if the option for hydraulics is available????

Mechanical disk brakes were designed to replace linear-pull brakes, so they need long-pull levers--levers that pull more cable for less caliper motion. Road brake levers are short-pull. So you might find that 105 levers simply don't pull enough cable to fully actuate those calipers.
One solution might be brake Travel Agents by Problem Solvers (https://problemsolversbike.com/produ...djuster_-_6417). They'll increase the pull on the lever end, but attaching them to the caliper in lieu of a brake noodle where there is no noodle might be a problem.
In earlier days of road disk before fully hydraulic disks became ubiquitous, there were hybrid calipers. These used a fluid reservoir and piston in the caliper that was actuated by a cable. You might ask your local dealer if these are still available. Good luck.

I mean, there are many reasons to keep with cable actuated:
- Cheaper, especially when you already have the calipers
- Easier to maintain
- Ease of repair, especially when bikepacking/touring and having to carry your tools with you
- Possibly more durable
- More resistant to fade
- Better control of the contact point- how far to pull the levers before the pads contact the discs
- etcetera
Three people chiming in with the same unsolicited advice is arguably worse than mansplaining. Next thing you know, someone's going to say, "You should smile more often."
To answer the original question: yes, the 105 rim levers will work fine with the Spyre calipers, which are made for road pull.
In fact I have 105 5800 levers with a Spyre brake and they're doing fine. They don't grab well (especially in the wet), but that's probably because of the aftermarket pads I'm using. The only issue is that the return spring on the Spyre is pretty strong, so I ground it down

Can't you all take suncruiser' word that:

Per their post, the OP has a Vaya. The OP wants a 105 groupset, but does not appear to have bought one. The OP wants "to keep cable actuated discs," insinuating they already have cable discs. The OP makes the statement that "The 105 disc groupset is hydraulic." but again, no mention of having bought it yet. Now, if the OP had said "my 105 disc groupset is hydraulic," then that would be different. But making a statement about something does not imply possession of said object. Me saying "a million one dollar bills is very heavy" does not mean I have one million dollar bills.
And the meat of the post: "Will the 105 rim levers work with my cable discs?" which later revealed in post #3 will be (but are not necessarily currently) TRP Spyres.
The only parts the OP ever claimed to have were Claris components. So, assuming this was an off the shelf Vaya with Claris, the OP has had- and maybe still has- Hayes CX Comp cable calipers.
I do not see anywhere where the OP has claimed to have anything hydraulic.

No, they are not. Hydraulics are easier to maintain by a mile. Cable discs require periodic adjustments. Hydaulics adjust themselves. Furthermore, a hydraulic line is sealed and will last longer before needing replacement than a cable.
Not really an argument. If you have an argument to make, then make it.

Is it too much to ask that you respect the OP's preference for cable discs?

if someone asks a question on this forum (on the internet in general), providing a suggestion that they consider other options is not 'disrespect'. Many of us here have years of experience with the subject and we answer accordingly. You suggesting that we are somehow committing a wrong against the OP for making such suggestions is more disrespectful than us telling the OP in a polite manner that they may not have all the information needed, based on our experience.

Back to OP's question, yes 105 mechanical levers will work with Spyre brakes. I have a bike with this configuration, no issues.

Thanks for all the input guys. Yes, I have thought about just bumping up to hydraulic brakes, but hydraulic brakes have a distinct problem (in my personal experience) that I'm trying to actively avoid. It looks like I'm going to be stationed up at fort Wainwright, and I have found from living in Fairbanks before that hydraulics dislike extreme cold. I didn't stop riding until about -30f before, and I have no intention of changing that when I get up there again. Yes, hydraulics are much more powerful, easier to adjust and have much more modulation. This is why I chose the spyres, the dual pull will to some degree give me some of that modulation and power. It is actually going to be equipped with the spyres by the end of the week, it's at my LBS to have them and the new brake cable installed, and will be running on the claris equipment for the next few months until I piece together my new drivetrain. Thank you to all who have defended my decision to stick to mechanical brakes. I'm trying to put together my ideal machine here, and I'm pretty set on the way I want it to be set up. Really looking forward to the change from Claris to 105, and the new wheelset I will eventually acquire as well.

I'm going to use my standard 2 bikes year round. They will both be equipped with studded tires that will fit under the fenders. My Trek District 8 and my Salsa Vaya Claris that won't be Claris anymore

Got her back today...
Gotta say, I like the new looks! Spyres and the new version 2 piece rotors look good together. Now onto the 105 groupset.
