I'm interested in trying these out, but it seems there's some mixed opinions on them. I'm typically a RH tire guy, but am curious about these. Maybe you bought a set but didn't like them? Or purchased a set and never mounted them?

If you have some you want to pass along, please let me know!
Thanks!

Hey Brian, I don't have any to sell, but just sharing my experience: these were the first tires I had on a Crust bombora and they did not hold up well -- but I've had 3 other sets of UDs since then, including one on an AHH, and they have been great -- hold the air and roll pretty fast. I like them better than RH. In any case, good luck!

Thanks for sharing your experience, Ryan! This is helpful. Coincidentally, these would also be for my Crust Bombora, which desperately needs new rubber to replace the RH knobbies that I've had on there for the past couple of years.
I'm curious to hear why you stuck with them after not having an initial positive experience - they're so pricey! I've read various accounts of them being loud on pavement, notoriously leaky, and overall not very robust... but then I've also heard from folks who speak highly of them.

I've tried them a few times because I think they look beautiful and I really want to like them because of that but they did make a lot of noise and they ride slow and heavy. Not really sure how else to describe it. Come from RH they were noticeably sluggish. I tried both the race and JFF casing. They both felt like the same ride to me. I am back with RH and very happy. BUT loads of people still love them and tires are a personal thing.

Hey, Brian -- yeah it's a good question! There was rip in the sidewall of the first set -- they sealed up OK but would still flat more than I could deal with. But I was feeling charitable and chalked it up to bad luck. From there I got the 2.2s and loved them, then when I got a new wheel set for the Bombora, the shop owner recommended combo of the 650b cava/rose so I did it again -- and again had really good luck. My latest addition is a set off 700s for the Hilsen, replacing RH.
I didn't feel much of a speed drop-off from the RHs and I just couldn't deal with how fussy the Renes were - I was filling them up every other day.
Possibly just bad luck. And also it's just me -- I would much rather pay a speed penalty (up to point) than have to air up tires once a week. One of my fav sets of all time are the specialized pathfinders my wife has on her Joe App. Nothing fancy, a touch heavy, but these tires have not needed sealant or even air for 8 months and they roll over everything.

I swore I saw a pair for sale recently somewhere and am trawling around trying to find them - in the meantime if I could pile on my unsolicited advice too.  I feel similarly to the others; I've worn through 2 pairs of the 650x48 Rose race grey, which is to say I clearly find them useful, but couple important points:  I would say they are slower, louder, and less overall grippy than the Rene Herse knobbies, and their casing is equally prone to tubeless trouble (if not more). Sadly you will not get away from luck-of-the-draw tubeless incompatibility, which is true of everything Panaracer makes it would seem.  I only run my Panaracers with tubes, personally. 

Why do I keep running them, then?  I find they are great with fenders - the more slick center section and widely spaced, lower profile side knobs don't pick up stones and sticks like RH knobbies do. They also obviously look great.   If you want a fast rolling, easy tubeless, grippy tire in 650x47/48 I suggest the Terra Trail from Continental. But if you want the grey good looks, I don't blame you, and they're still a good tire. I would only run them with tubes though.

my only difference here is that other than the first set, I've had no trouble at all running the ultras tubeless -- the JFFs hold just fine (the knobbies esp are def loud, tho). RH has been a nightmare on that score.

This is really great to see everyone’s experiences with these tires here, because I don’t recall seeing much discussion about them at all in this group.

Also surprised to hear so many people having trouble with RH tires. I’ve had no troubles with the knobbies (I’ve run them both with tubes, and tubeless). I find them adequately quiet on pavement too, IMO. My only issue was difficulty getting a set of knobbies to hook up with my air compressor on a tubeless setup once, and I had to get my shop to do it. All my RH slicks are run with tubes in my stable.

I should also mention, if you’re wanting to go tubeless with RH gum walls, and tend to ride rougher terrain, I’ve had the best luck with the endurance casing options that RH offers on certain tires. Those sidewalls seem plenty robust, and I’ve had no leeching of sealant or like some other lighter weight varieties.

I’m also interested in Ultradynamico tires, and wanted to ask this question without creating a whole new post. I hope that’s okay!

I have a 54 cm Homer from 2011 and was wondering if the Cava Race 42 would clear. I have Tektro R556 brakes which I was thinking might be an issue but not exactly sure.

hi, Anthony -- my homer fits these exact tires easy, but it's newer. here's an old conversation on the topic and/or you might want to just check in with Will,

Hey Ryan, thanks for letting me know! 

Do you know if the brakes might cause any issues? The reason I ask is because the Tektro R556's tire clearance info is a little hazy.

Also what brakes are you using on your homer?
