Also. I didn't point this out in the last post-but I ran baby shoe and rat
traps (neither were the extra lites) Even though they eat glass, I have only
really had one cut large enough to patch. When I DID get a flat I saw all the
glass and shards embedded and plucked it all out with a needle.
I’ve used the Antelope Hill, Steliacoom, and the Stampede Pass tires in the
past and never had flatting issues. I wouldn’t use them as a durable commuting
tire though...that’s not really their purpose.

My bad. Got suckered into a &%%$@! zombie thread. I find these almost as
annoying as slashing a sidewall on a new tire. C'mon people, if a thread
was started 4 years ago and last zombied two years ago, it's okay to start
a new thread, even on a similar or identical topic. This has become a

I've switched to running a 2.1 racing Ralph on the front and a RTP on the rear.

Thanks Phil!
Yeah, my rim is 20mm on the inside and 27mm on the outside and the tire
measures 50mm. One SV14 blew at around 48 psi, one survived ;) A Michelin
"tank" tube replaced the other.
Unfortunately one tire is a complete banana, very poorly crafted, maybe by an

The tires are made by Panaracer, and these tires are made by hand - which
may explain why there is a slight difference in weight, yet crafted very
carefully.
The RTPs are some of my favorite tires, if only they made more bikes that
fit them. I would get the SC 14s, as the tires on 23mm outside
Hi,
I feel a bit crazy as I just received a pair of these... well, it's my

some who'd know a bit more?

Since the blurb you are commenting on is about Compass tires in
general as opposed to just RTP, let me just say that, I think they
handle just as well as anything else out there in the rain! I've done
quite a few rainy rides on them, on warm days and cold ones.
I also get many less flats than on
Thanks for sharing the link, Jan. Very informative and often entertaining
discussion. Candid, too, but respectfully so. Nice that you're getting
recognition for all the tire testing contributions you and crew have made
over the years.
Quite interesting was discussion of the effect that wider
The EL casing is so much more supple than most tires that my realization of
too low of a pressure in my Stampede Pass Els was a low speed washout on
the switchbacks of multi user ramp on a repurposed bridge, decked with
concrete, on a sunny dry day, just as Clayton's. No "mold release" or bloom
That is interesting stuff, but I think the idea that wider tires are a
disadvantage on smooth roads is a bit outdated. I wonder when this video
was recorded.

The Rat Trap Pass use the same casings, same tread pattern, and same tread
thickness as the other tires in the Compass line. We did a lot of testing
with prototypes to make sure that you could actually use such a supple
casing on such a wide tire – nobody had ever done that before.
As to tread
It's not clear to me why a tire would have to grip worse in the rain to be
faster. Both grip and speed are improved with softer rubber – ask any
skateboarder about this! So a tire that grips better in the rain also will
be faster.
When you compare tread patterns, the Pasela is basically a
Right. Key word is "look". They look slow, too, to some who haven't ridden them.
Love the last paragraph of the Riv quote.

The tread pattern on my RTP is the same as the one on my 700C Stampedes. A
fatter 26" tire with this minimal herringbone road tread will definitely
look pretty smooth.
Since this is RBW, here are their tips on tires:

They're certainly not cheap, but they're also not bald. Low profile file tread.
Pretty grippy, in my experience. Not Paselas, different feel, but also not
Kojaks... and not water skis...

These tires are expensive but fast. Corners like you might expect from a bald
tire though I don't push it. I think it might be a diff story if there were
actually wide 26 rim brake rims for these tires. Most of them are in the 17-20
internal width range. Grip is pretty decent, but Thunder Burts
I would agree with Gravel & Grind that most designers would be reluctant to
advertise shortcomings. But I was surprised at just how contradictory this
review was to the item description (ie, sales copy) on the Compass website.
Your review in a nutshell: Low mileage, repeated flatting, poor wet
No one is gunna claim their tires don't grip in the rain, especially if
they live in Seattle. I don't think these tires have bad grip, for what
they are, but Paselas have way more grip, in my experience. Paselas are
also slower feeling, and as the saying goes, there's no free lunch. Gotta
When tires are manufactured, the inside of the molds are sprayed with a
substance to make the rubber release after cooking them. Until that thin
coating wears off, the tires can be quite slippery. I learned this in the
motorcycle world, where it is VERY important to know your tires and what
Thats odd because Heine states that tge tread rubber is super grippy even in
rain,iirc.

Mark - take James word over mine, I'm not a fan of riding in the rain in
general and don't have many tires to compare it for wet riding conditions.

You also want to remove it from the tread of a brand new tire, for the
same reason.

Thanks both of you.

James, are you running the Extralights or Standards? Have you experienced
both? Worried about

I’ve had ‘em on my Hunqapillar for about half a year. I commute, do fire
