Here we go...bicyclerollingresistance.com finally tests the Compass Bon Jon Pass

This means that soon everybody will be riding those in TT's at the pro circuit?

Wow. Only 1.5 watts slower than Schwalbe......Marathons.

For those interested in the CliffsNotes version... fast rolling but terrible (their words) puncture protection.
FWIW, I ride a set of Barlow Pass tires and the tendency to flat has certainly not been my experience.

Its width leads to nontrivial aero penalty, and its rolling resistance isnt great compared to the truly fast tires |

"As my experience has been that the casing thickness doesn't make a huge difference in the rolling resistance tests" <- shots fired
I hope they test the Pasela next, as well as Compass' current closest non-Panaracer competitor, which is probably the Schwalbe G-One Speed Microskin? |

Also, I wonder why this is far off from TOUR's tests, which shows the Bon Jon as faster than the venerable GP 4000S II (on a smooth surface no less)?

I've never run Compass tires, but my understanding is that their suppleness, combined with low pressure, lets them deform more around a potentially puncturing object, thus preventing said object from penetrating. I think Jan's philosophy is also that preventing punctures has as much to do with technique as it does the tyre.

Odd especially since the Bon Jon was about 10 watts slower than the Vittoria and the Continentals usually are just 2-3 watts slower than the Vittoria tires on pavement. |

compass tires are awesome, I don't care what any article says. Puncture resistance is not #1 for them and neither is for me. If you do ride in a place full of glass or other crap, maybe not the best choice but I rode mine in NYC, commuted on them and not many flats. They key is to set them up tubeless, but even before that I never had many flats. I have had more flats on veloflex for example. |

The article reads as though someone made a peepee in the author's breakfast cereal.
"So expensive" "For such an expensive tire" etc.

Mine either. Very good puncture resistance actually.

Nice! I'm in LA, which has truly horrendus road quality, so it's good to hear that they can survive in an urban environment. What kind of lifespan did you get out of yours?

No surprise here. A thin, supple tire has low rolling resistance and terrible puncture resistance.
These tires have a cult-like following for what reason I have no idea, especially for gravel?? |
