@wgscott , thank you for the excellent description of your various parameters. It reinforces some impressions I have: you get what you pay for, though price/performance ratio flattens out at the top of the price range. That doesn't mean paying top dollar is stupid, though, for some.

I've been curious about the GP4000S-II (is that how you spell it?) for a few years now, and I finally saw them at a good price in France at xxcycle.com. I put them on my Lemond (fast handling lightweight racing bike) but the clearance between tire and seat tube was 1mm, and it made me nervous. Too bad. They fit fine on my McLean, steel racing bike with moderate manners. I took one 50-mile hilly ride on it and can't comment yet.

Another impression I have is that the big tire companies who do cutting edge R&D really do produce the best tires. So I don't use WTB, Nashbar, Performance, Maxxis, CST, Kenda tires, and I'm even skeptical of Specialized. The top brands in my mind are Vittoria, Continental, Schwalbe, Panaracer, and Michelin, in no particular order. Each of these companies has one or more specialties and one or more areas they stay out of, but when they try to make the best tire of a particular sub-class, they produce a winner.

Boy am I a tire nut. I could go on all day. Once I was driving a long way with a friend, and I got on the subjects of bike tires and car tires, and my friend in the passenger seat literally fell asleep.

I'd love to try those Compass tires, but it will take some time. First I'll be trying the Voyager Hyper tires on my gravel bike. They've proven great on paved streets. They have a lot of tread wear left.

FWIW, Amazon has a 2-pack of GP4000S-II for $80.

Not bad. I paid 58.32 € for my pair! But of course, I paid shipping.

I just took off my perfectly good GP4000S-II and replaced them with a third set of 38mm Compi.

I shall try them at Crater Lake. What could possibly go wrong?

I just got a pair of barely used Chinook Pass EL tires in 28mm. I will see if they live up to the hype.

so, $$ aside, are these commuter friendly for pavement/cobble stone/riding through NYC's generally ****ty and varied streets? Would love to put them on but I cannot be worrying about flats - especially because I use pitlocks so changing flats is a royal pain in the ass. Thanks brothers & sisters & sister wives.

The tread is 3mm thick and no puncture resistance belt or lining. That said, no flats for me yet.

I generally ride tires with no puncture resistance. I don't get many flats, and when I get one, it's no big deal. It's not pleasant to change a tube on the road, but I get by. I'm thinking of getting pitlocks. I suppose it would help if I had a wrench I could use on the pitlock key for extra leverage.

I'm in NYC, also, specifically Manhattan. Glass isn't all that common on the streets, and I steer around it when I see it. Potholes and cobblestones are a problem only if your tires are under-inflated.

I currently ride Big Applies by Shwalbe (26 x 2.35 on my surly troll) and almost never get flats, until the tire degrades to nothing at which the flats start. Pitlocks are amazing and bring a total peace of mind but yes, you have to carry more equipment with you to change the tire, and on the way to work in heat or snow - and especially with godforsaken horizontal dropouts - they make changing flats a whole hell more annoying.

I guess I'm really wanting to pull the trigger on these but want to be sure. Noglider are you using these in the city?

@bikiola , not yet. I just got a pair of slightly used Compass tires, and I think I'll try them soon. I'm really not worried about flats. I do worry about sidewall wear, though. People extolled the virtues of Veloflex tires, and I was very disappointed with how short they lasted, but I guess the target market is different for those. They're very narrow.

I recently started riding Continental GP4000S-II tires on the racing bike I keep in the country. I got them in 28mm, and they are pretty fantastic. My impression is that Continental tires are quite durable. I believe this model has no puncture protection, which is a plus for me.

On my fixed gear I ride 28mm Panaracer Paselas T-Serv messengers in NYC. They are a good compromise for ride/puncture resistance. However I'm very Compass curious. Between Compass or Clement Strada LGG or Challange Strada Biancas (if I can squeeze them on my Soma Rush, claimed 30mm).

On my road bike I put some 25mm Veloflex Corsas and so far so good. They are a nice light responsive tire. No sure how durable yet.

I have the Clement Strada LGG on my commuter bike, in 32mm, 60tpi (the coarser choice). They are OK and not great.

Wondering if the 28mm 120 TPI versions are better.

I rode some 25mm, in I think 120 TPI and really liked them on a rental bike.

What's interesting to me about these is that the skinwall version is only available in the 60tpi casing which seems counter intuitive.

They're ok tires but there are much better options for pretty much every metric.

Good article. I got these tires cheap, so I'm satisfied, but I don't recommend them. Since mine are 32mm, I can run them at low pressures and be comfortable. You just gave me a nudge to try the Compass tires.

They have a layer of Vectran-based fabric under the tread rubber. Most performance-oriented road tires have something similar. They're usually pretty marginal; the marketing guys like to say that the tires have a puncture-protection strip that adds no weight or rolling resistance, but those super-thin strips usually don't do much to protect against punctures either.

So mine survived the Crater Lake test without incident. (The roads are beat up, but shouldn't have much crap on them compared to city streets.)

The bad news: I put my 28mm Clement Strada 120 TPI on my son's bike. It wasn't enough to slow him down to the point where I could keep up.

Therefore: Being young and fit is more important than tires. But mine look better, and the ride felt a lot easier than it did three years ago (which was probably also because I ate Cliff bars back then). The bike seems to float over road imperfections.

I am really worried that re-branding "Compass" to "Rene Herse Cycles" is going to add needless weight to these tires and reduce their compliance and increase their rolling resistance.
