Anyone tried cc pro and tannus in the same bike/same tires as a direct comparison?
I've tried both now with the same bike, same tires, same tire pressure, same trails (Eagle), very similar conditions (but slightly different wheels and two weeks apart so it isn't a perfect comparison).
CC Pro setup: Continental Der Baron Projekt 29x2.4 tires, 19psi front, 20 psi rear with CC Pro on both ends on WAO Union rims on my hardtail.
Tannus setup: Same tires, same psi, same bike, Tannus Tubeless on both ends on WAO Agent rims (which WAO says are a bit stiffer radially than the Union rim).
I've been running CC Pro for about 1.5 years so I'm very used to it. I have only one ride on the Tannus setup so these are just my initial thoughts.
Impacts - I didn't feel any real difference between CC Pro and Tannus at these tire pressures. I didn't case anything or smash anything too nasty. There is about a 200m section of trail filled with baby heads and jagged rocks that would definitely have resulted in rim strikes without inserts. I didn't feel any rim strikes with CC Pro or Tannus. Can't comment on really hard impacts though. Both seemed to work about the same (well).
Sidewall support - They felt pretty much the same to me at these pressures. No squirm. Both are excellent.
Ride feel (not cornering) - There's a noticeable difference between Tannus and CC Pro here. It felt to me like CC Pro has a more significant damping effect on trail chatter. Tannus felt a bit more direct / energetic. On a hardtail at least, I think CC Pro is a bit more compliant feeling than Tannus. I don't suggest that's a good or bad thing necessarily. Just different.
Weight - The ~100g per wheel weight difference between the two is noticeable climbing, particularly in techy sections and/or where I start to feel gassed. I don't think it's noticeable descending and it wasn't really noticeable on flat terrain (not that there's much of that around here).
I'm going to throw the Tannus on the Union rims to see how that feels and will mess with tire pressures more.
My initial takeaway is that assuming you don't care about the ability to ride out on a flat, I'm thinking go Tannus if you want quicker feeling wheels and go CC Pro if you want to maximize the magic carpet ride feeling. Again, assuming not caring about being able to ride out on a flat, I'd probably lean towards Tannus for a full suspension bike but would have more difficulty deciding for a hardtail.
Final thought: I've also used Cushcore XC on another bike for about a year. Now that I've tried Tannus Tubeless, I don't see any reason at all to buy Cushcore XC. I think you get better sidewall support from Tannus (on a 2.4 width tire at least) with better (or at least equal) damping of trail chatter for about the same weight and lower price.
