Compass Elk Pass vs. Panaracer Pasela, Part II

Posted on by

I promised to update my experience with these Compass Elk Pass tires after riding them for at least a few hundred miles.  Well, I’ve only put about 60 miles on these tires and I’ve already had my first flat.  That experience led to some other important realizations about these tires and the Schwalbe tubes I purchased with them from Compass Bicycles, a few months back.

Schwalbe tubes vs. Qtubes – 26″

To say that I am in a good mood this evening, after walking my bike home (rather than repairing the flat on the road – to be explained later), and then spending nearly two hours attempting to repair my flat rear tire at home would be incorrect.  First, though, I’ll talk about how these tires handled out on the road – before the flat.

These tires are lightweight – significantly so in comparison to the Pasela’s I had been using.  That reduction in weight, and the nature of the tire’s properties led to an enormous increase in my enjoyment of cycling on my Terry, which features 559’s front and rear.  The Elk Pass tires are fast and responsive under acceleration.  Accordingly, I found myself riding more aggressively than normal (but maybe that’s not such a good thing).  They are comfortable tires, and while narrower than their advertised width (32mm vs. actual 28 mm on my rims), the plush ride they provide feels like 38 mm tires or more.

The flat I had today occurred on pavement, and without any observed road detritus such as broken glass or thorns.  Within seconds of hearing a strange noise while climbing, my rear tire was flat.  This fortunately happened while I was cycling at  low speed.  The tire went TOTALLY flat – something that really can’t happen with regular clinchers that have more robust sidewalls.  The sidewalls on the Elk Pass tires are so supple that once the tube lost air, the tire had nothing to support it.  These tires are very much like a tubular in that respect.  Since I was only about a half mile from my house, I tried inflating the tube to see if I could simply coast home before the air made its way out.  No luck there.  The tube would not hold air at all.  So I removed my bags and walked the bike home with the rear wheel elevated, so as not to further damage the delicate sidewalls.

Once home, I examined the tire.  I couldn’t see any obvious cuts or sidewall cracks.  But, that’s not unusual when assessing a bicycle’s flat tire.  When dealing with flats, I normally unseat one side of the tire’s bead, take out the tube and then inflate the tube to determine where the puncture occurred.  That way, I can see where the tire is compromised, and if a projectile needs to be removed.  This tube went flat so quickly as I tried to inflate it that I ended up removing the tube from the wheel and closely examining it for the source of the puncture.

I hadn’t used the tubes that Compass had recommended for these tires – Schwalbe SV12 tubes which are wide and heavy in comparison to the Conti 650c tubes which have worked well for the 559 Paselas I had been using on this bike.  Since my existing tubes were good, I re-used them when installing the new Compass Elk Pass tires.  Upon close examination, I determined the source of the leak and then searched the tire for that location.

And, voila, here is the tiny little cut in the tread area.  Although very small, the cut bulged out once I had a new tube installed, so I booted this area with a folded dollar bill.  This experience made me want to mount the heavier and wider Shwalbe SV12 26″ tubes which are recommended (and I think this is due to the delicate nature of this tire’s construction), but after hours of trying to make these too large tubes fit into my tire and rim, I gave up (and remember that I recently mounted at 700c tube into this rim, with success).  The Compass recommended Schwalbe tubes are simply too large in diameter and too wide to enable them to work with this tire and on my Mavic X221 rims.  I tried dousing my hands, tires and tubes with some carcinogenic talcum powder to see if I could get these tubes to flatten out and not bunch up inside the tires.  NO SUCH LUCK.  And now, I am probably radioactive…

Tires I have loved, and a few I have hated.

Cypres 650b

The amazing array of wheel diameters, tire widths, tread patterns, sidewall construction, and the debate over fat vs. skinny widths, and high vs. low tire pressure inspired me to share my own experience with bicycle tires.

I am also a motorcyclist, so my knowledge of tire performance and traction is informed by my understanding of how tires function on motorcycles. A lot of the same science carries over to bicycles.

In my own personal collection of bikes I can count 9 different rim diameters:  700B, 27″, 700c, 650c, 650b, 26″ metric, 26″ English, 26″ MTB, and 24″.  From there, rim widths vary, spoke counts and lacing vary, and tire widths vary.  Wheel construction also has a very important impact on ride quality. In my opinion, more spokes on the rim are better than fewer, and wider rims are better than narrower ones, at least for all non-racing applications (that is to say, most of the entire cycling population).

The research on tire width and construction relative to speed and comfort is very limited.  So I give kudos to Jan Heine and his team for sounding the alarm about narrow high pressure tires and their negative effect on performance.  Not to mention their negative effect on comfort, and the limiting effect they have on a cyclist’s ability to safely explore her or his surroundings.  Since most cyclists don’t have hundreds to spend on tires, not to mention thousands to spend on custom built bicycles, it is important to consider real world, long-lived, and reasonably priced tire and rim options.  Cyclists who use their bikes regularly for transportation figured this out long ago.

For anyone struggling to understand the bizarre nomenclature surrounding tire sizing:  you are not alone.  There is no consistency in size labeling (although that is improving), and even among tires that are purportedly the same size, there can be perplexing variation which can make it hard to mount the right sized tire to your rim.  Sheldon Brown’s site has a sizing chart and discussion which help to explain the strangeness surrounding tire sizing nomenclature.  If you are confused, join the crowds!  When in doubt, always measure your effective rim diameter in order to determine the correct tire size for your bike.  If you are removing a tire, it’s quite easy just to look at the size indicated on the sidewall to make sure you replace the old tire with the correctly sized new tire.  If your rim doesn’t have a tire, it probably has a rim diameter stated somewhere on it, if it is a newer rim.  Many vintage rims have no diameter indicated.

700A tires from the Land of Oz

Original 1929 Dunlop Le Pneu tires

700B tires

When I was restoring a 1929 Griffon, I needed to replace the corroded Dunlop Le Pneu tires.  No diameter was indicated on the old tires, so I measured the rim diameter and ordered 700A (642 mm) tires, which had to be shipped from Australia, as they were not available anywhere else in the world that I could determine.  When they arrived and I tried mounting them, I realized that I should have ordered 700B (635 mm) tires.  I incorrectly measured the ERD on the 1929 Westwood rims.  In retrospect, since I had the original tires, I should have measured their diameter instead.  700A and 700B sizes are not listed on Sheldon Brown’s chart because they are considered obsolete.  However, I found the 700B tires on Amazon, but you may be able to find these sizes in Canada and France, in addition to Australia.

So, what are my favorite tires?  And what tires will I never willingly ride again?  Here is my list:

My top three preferred tires for comfort, speed, and reliability are:

Compass Loup Loup Pass 650b tires

Panasonic Compass Loup Loup Pass 650b 38 mm – I use these on my 1980 Meral.  They are comfortable, oh so comfortable. I haven’t had a flat yet after a few thousand miles of mostly urban riding.  I keep the pressures low at 46 psi rear and 42 psi front, which seems to provide the optimal compromise between comfort and handling.

Panaracer Pasela Tourguard – 559mm/ 32 mm

Panasonic Panaracer Pasela – in all its models and sizes – used on my Terry and on many other bikes I have ridden.  I have found these tires to be very long lasting, although I have gotten a few flats on the folding version I use with my Terry.  Whether or not they are easy to mount really depends on your rim and whether you are using the folding vs. clincher model.  I prefer the folders because they are easy to carry with me when I am touring. The 27 inch size has a different tread pattern.  These tires are affordable, reasonably comfortable, and fast enough.  They are a good choice for all-round riding which is why I generally use them for my restoration projects.

Compass McLure Pass 26″ tires – used on my Panasonic MC 7500 errand bike.  These tires replaced the frighteningly compromised Nimbus Armadillo 26 X 1.5 tires I had been riding.  The Armadillos, while never having a flat in over 6 years of use, were heavy and not very comfortable, not to mention the fact that they were splitting apart at the seams.  The McLure Pass tires have made the MC7500 faster, and much more comfortable to ride.  Tires really do make a difference!

My three second tier tires – good value and a decent ride:

Continental 700c Gatorskins

Kenda Raleigh 26″ tires

Panasonic Col de la Vie 650b tires

While I could mention many, many tires in this category, my top three mid-range choices reflect my own interests as well as the particular bikes I ride.  So, don’t take them to heart, too much.  The Continental Gatorskins are great tires for 700c road bikes.  I rode Gatorskins over many, many miles on my 1986 Centurion Ironman Expert.  They were comfortable for a narrow 700c tire, and I never had a flat in all those years.  The low-end Kenda tires on my 1950 Raleigh Sports Tourist were a surprise.  I had expected these tires to be really horrible, and had purchased them as a placeholder until I could find “better” tires for this vintage Raleigh.  In fact, the Kenda’s proved comfortable as well as bullet proof.  I’ve had no flats in the eight years I have been using these tires, which show no signs of wear, and no sidewall cracks.  I have mixed feelings about the Panasonic Col de la Vie tires pictured above.  I tried these tires out on my 1980 Meral, and they were quite noisy, slow and ponderous.  However, these tires have worked well on the older 650b bicycles I have restored, so I list them here as a decent option for a 650b rim.  In this category I should mention a few other tires I have ridden:  Ritchey Tom Slick 26″ tires, Panaracer Ribmo, and Vee Rubber Micro knobbies.  All equally reliable and of good quality relative to price.

Tires I Won’t Buy Again:

In this category I include the Specialized Armadillo tires, noted above, which literally split apart at the seams.  I also include WTB tires – namely any of their 700c touring tires, which are noisy, heavy and very uncomfortable. I also will not ride any Continental Touring tires.  Continental’s offering is not really a touring tire, but instead a heavy and inflexible tire which is not even okay as a commuter tire, as there are many other nicer options out there (see Panaracer, above).  However, Continental does offer other tires which I do like.  I won’t buy any Schwalbe tires, no matter what the model, as I have found them to be unbelievably uncomfortable and heavy.

I do like micro knobbies as an interesting option for multi-modal cycling.  I used these Thailand manufactured Vee Rubber tires on my ALAN with very positive results – they were fast on the road as well as sure-footed on gravel.  While tire choice is not only highly personal, it should also be based on the type of riding you do, as well as the type of bike you are riding. If you are not happy with your current tires, it doesn’t hurt to think about other options.  I have found that ride quality is significantly affected by tire choice.

Back Out on the Road

It’s been exactly three months since I’ve thrown a leg over and navigated a beloved steel framed bicycle.  That’s how long it’s taken for me to recover from my unfortunate mishap involving a ladder and my fibula. But once I got my doctor’s go-ahead to begin cycling again, I was anxious to get back out on the road, although also strangely apprehensive.

At Benham Falls

The last time I was on my bike was in Central Oregon’s fall glory, enjoying the dry climate and the very nice bike paths leading to Benham Falls.  I was riding my Terry, feeling slightly under the weather due to a dodgy restaurant experience earlier in the day.  But, once my riding buddy and I arrived at the Falls, all was well with the world.  The bike paths were strewn with slippery pine needles which kept getting caught in my “over the top” fenders, but this was less worrisome than the gravel portion of the journey over lava rock and loose gravel.  Fortunately, the Terry handled well, with its 32mm Pasela’s and great frame geometry.

Velo Orange 126mm freewheel hub

So, for my first adventure back in the saddle I decided to ride my 1987 Panasonic MC 7500 commuter bike.  It is a very forgiving bicycle, although a bit tall due to its high bottom bracket. Before my leg injury I had installed some new tires on this bike to replace the heavy Specialized Armadillo tires, which had literally split at the seams, with something a little nicer – Compass McClure Pass 26 x 1.5 ” tires.

I had been riding these tires for a few months before my mishap and was looking forward to reporting on their ride quality, which I can now do. These tires have allowed me to ride in one higher gear overall, as compared to the Armadillo tires I previously used.  They feature a bit of a tread pattern which can help on non-paved surfaces, and are very responsive and comfortable.  I’m sold!  I also wanted to provide an update on the Velo Orange freewheel hub which I used to replace the failed Quando sealed bearing rear hub – a hub which failed after only about a thousand miles of use.  My new VO is working perfectly, and shaved some weight off the bike due to its drilled flanges.

Cardiff leather saddle.

Gardening with the Panasonic.

I use the Panasonic a lot for around town errands.  To make this bike a little more comfortable I added a Cardiff leather saddle, replacing the the old vintage Avocet touring saddle I was using.  I like the Cardiff saddle as a Brooks alternative – the saddle rails are a bit longer allowing for greater adjustment nuances, and there is something about its shape and geometry that seems to work well for me.  My first ride today went very well.  I didn’t experience any mysterious lapses in “bike memory”, nor did I have trouble climbing or descending.  Although it is winter, I’m looking forward to some enjoyable riding on the warmer and drier days which can sometimes appear unexpectedly. See you out there!
