Doesn't look like I'll be able to swing for a new bike this year but I can probably upgrade a few things. I'm currently running Ksyrium SLR's with TRP R970 SL brakes. Using the exalith brake-pads. Braking is so, so and kind of loud. The TRP brakes aren't so much brakes as they are acceleration inhibitors. My question is whether I should ditch the Ksyriums for Dura-Ace C24 TL wheels since they have a regular brake track or if I should keep the Ksyriums and install Dura-Ace calipers. Basically, I just need better braking and I'd like to try tubeless. The best combo would be to get both the wheels and brakes but that's pretty pricey. Thoughts?

What kind of brake track do the Ksyriums have compared to the Dura-Ace?

The dura-ace brakes are probably the first component to switch to IMO.

If braking is your reason to change and you are changing to DA callipers then that is about it for what is out there. DA brakes are about as good as road callipers get never mind that I have Record Brakes which can be awesome too. One of my bikes has Gravitas brakes which are strong but don't modulate as well as the Record brakes. The rear is a dual pivot and more stopping power than the rear single pivot Campy. I prefer the single pivot Campy over the dual pivot as I think the rear brake is already powerful enough to lock up my rear wheel but that said some guys want more.
Aluminum brake track and maybe try a few different pads. I like Kool Stop Black pads as they don't pick up much aluminum off the brake tracks. The Campy pads are better for stopping power and modulation but you really have to pick aluminum flakes out of the pads regularly. The Kool stops don't modulate as well but have about equal ultimate power. For Carbon rims? I have no idea.
I also can't think of an aluminum rim that is better than any other for braking. Mostly just keep the brake track clean. I don't know how the Mavic surface treatment affect their brake performance but almost any other wheel would be about the same.
For an all round wheel at pro level I love Campy Shamal wheels. Aero is pretty good, stiff as you need them, about as light as any aluminum wheel from anyone, and available in tubeless too. Get the cult bearings and the lowest bearing drag available. In a clincher this wheel beats a lot of deep section carbon rims for all round use including aero as these wheels have very low spoke counts with bladed spokes and have a decent aero performance. Not TT or off the front fast but in a pack these wheels are better than deep section aero wheels in many ways. I have certainly won roll down contests over other riders with deep section wheels and not all was attributable to my mass

I should explain that the aluminum braking surface on the Mavic's is really unique. It's jet black and has these swirl marks etched into them. They call it Exalith. While I think the all-black look of the wheels is awesome, I'm definitely leaning towards the Dura-Ace wheels and brakes.

I think the combination of the Mavic rims and TRP brakes isn't too awful great.

I have heard nothing but great things about the new DA calipers.....but haven't ridden them.

My favorite brakes are still the Mavic SSC brakes with the leaf spring. Just simply awesome. I have been riding my now for 13 years (!!!).

But what is with all this "pay" stuff? You're in the industry now, son!! Work the system for some schwag!!

No experience with that coating but I must presume it is there to preserve the brake track and still provide good braking. Does Mavic have a brake pad recommendation for this rim material? I had Mavic's ceramic coating on my MTB rims. I don't think the braking was as good as a clean dry rim but after a few km in wet conditions and V brakes that they were about the same as alum rims. Pads wore out a little faster but rims lasted more than 1 or 2 years

Actually, the SLR's don't use a coating like their ceramic rims. Rather, the braking surface is etched in a swirl pattern. You'd have to look at them really close.

The exalith braking surface didn't really catch on in the market because it is so much more expensive to produce.

Oh yeah, CK, I do seem to find some good industry deals but I still have to pay for a portion of it. Even at cost, the equipment is just too expensive.
