Compass tires: from skeptic to believer

[cmg]

What is the weight difference between the Chinook and the gbs you wanted to purchase? Is it the rotating weight difference that got your 2 mph increase?

No. Compass (now Rene Herse) tires are manufactured by Panaracer to RH specifications:

For the Compass Extralight models, Panaracer uses a casing usually reserved for their top-end racing tubulars. Panaracer doesn’t use this casing on their own clinchers.

I think I am probably in the minority as most everyone else seems to love them but I bought some G+ when they first came out. I now only use them on the indoor trainer. I really have zero love for them having had the rear wheel repeatedly slip out and slide on wet concrete in turns. And I don't think the ride is anything special. If you want tubeless compatible I'd look at the IRC formula tires - lovely tire. I like Compass alot but haven't tried anything smaller than a 32 from them - yet.

Hey Greg -

Thanks for the excellent feedback. Both the G+ and the Compass aren't tubeless compatible, (best I can tell) so that rules them out for me. I was thinking of going the Schwalbe Pro One route, but it looks like the reviews for the IRC are pretty sterling. I'll give those a spin instead...

Pro One tubeless in 700x28mm is the best all-around tubeless road tire I have ever used.
S-Works is also good but not as durable.

John, does the pro one fit true to size? I’m thinking of ordering some to try tubeless on a Hed Belgium+ rim but I’m worried about chainstay clearance. The vittoria Corsa G+ 28mm are more like 30mm at 50 psi. I wonder if the pro one would get wider too. Thanks!

No. I ran 25mm pro one tubeless on a belgium plus rim and they measured almost 29mm. But they were great!

Update on my Snoqualmie Pass tires: a bubble is forming in the tread of one tire. I removed the tires and the beads stretched so I had a hard time getting them to snap back out to the rim, even with a compressor. I found a high flow air duster in my tools that finally worked. I wrote Rene Herse about replacing the bubbled tire under warranty almost a week ago and haven't heard back. Leakage of sealant through the sidewalls continues (using Orange Seal Endurance). In summary, tubeless performance of these tires is lacking.

I just got a set of the Snoqualmies as well. I need to build up wheels this week for them, but hoping for the best with these. The reviews kind of seem to be all over the place. Fingers crossed.

I had the same issue with the same model last year. Sounds like a bad batch of tires. Contact compass and send that photo...they sent me a replacement no questions asked. The sidewall weeping problem seems to be fixed with their more recent batches as well.

Don’t write off compass due to one bad experience. If you contact them, they will take care of you. I’m guessing there is a very small margin of error in manufacturing tires of this caliber, so there are bound to be a few duds. My current snoqualmies have about 3k on them and have been ridden in countless gravel events that have tested their durability and my confidence in them...I am never short of amazed at what they can handle. And, I’m 240 lbs

Anybody have a recommendation? I got the Snoqualmies all mounted up onto Belgium Plus hoops. They mounted up beautifully with no compressor needed. They started inflating right away so that was awesome!

My concern is that I never heard the tubless “snap snap” through the inflation process. The molding line is very even and visible along the tire/rim, but i’m hesitant to ride them since I never heard the snap. I brought them up to max recommended pressure of 70 psi as well. I worked with them with no sealant, sealant as well as a little warm soapy water.

I do have an email out to Rene Herse, but thought I would check with the hive in the meantime. Thanks!

If the molding line is even and correctly located, I think youre good. Lubricating the rim with soapy water may have precluded the audible "snap" of the bead seating.

Correct. Like I mentioned, I did reach out to Rene Herse and they pretty much said the same thing. As long as the molded line is even and visible around both tires I'm good. That was kind of what I figured, but figured I would inquire anyway. I've gotten about 50 miles on them thus far. They are a sublime ride and we'll worth the money in my opinion. They are currently measuring just a hair under 44mm on a Belgium Plus wheel. There is no weeping of the sidewalls (I did get the extralight in black) and they are holding pressure really well.
