[RBW] Re: Tested 6 pairs of 700c (29in) tires - results and impressions

2015-09-08 Thread Lungimsam
Matt,
BQ studies tire construction to determine which designs give the rider the 
fastest and most comfortable ride quality.
It is alleged that the speed percentages measured in the BQ studies (like the 
slowest tire tested was ~20% slower than the fastest tire tested., iirc) adds 
up over long distances. So a 10 hour ride with the slowest tires, in theory, 
would take only 8 hours on the fastest tires.

I have not noticed significant speed increases with GB or Compass tires over 
others I have ridden. But they are very comfortable, seem to keep their 
momentum up very well when starting up a hill, and their cornering is 
fantastic. I didn't get the last two benefits from my Schwalbe Marathons, 
though they were also excellent tires.

I think they're using the power meters and controlled conditions to ensure 
measurements are as objective and repeatable as possible.  Not that the 
differences are undetectable without such equipment.

When I put on my Compass tires for the first time I sure as heck noticed 
the difference.  Vittorias always seemed harsh and uninvolved. Compass 
smooth engaging.  Not sure how those impressions could be measured under 
controlled conditions with power impressions.

 Takahashi,

 That is an interesting comparison. Like you, I am surprised that our 
 Barlow Pass tires weren't super-fast. At first, I thought about why this 
 could be... until I realized that you did only one run with each tire. You 
 mention that yours isn't a detailed study, and you are right. It would be 
 erroneous to draw conclusions based on a single run, especially on a road 
 course where so many variables can change.

 It's very important to control all the variables when testing tires. 
 For example, at Bicycle Quarterly, we test on a track, and only when there 
 is no wind (measured with a windspeed meter, < 0.5 m/s; but looking at 
 trees and checking that the leaves don't move is equally precise). We also 
 measure temperature and correct for that based on a curve we've 
 established 
 by measuring the same tires at different temperatures. We do at least 
 three 
 repeats with each setup.

 On an open-road course, you'll have many more variables that change. 
 The way to deal with this is to do repeat runs until the variations 
 average 
 out. A statistical analysis helps you figure out whether you've reached 
 that point. (Bicycle Quarterly's tests always include a statistical 
 analysis to make sure we report actual differences between tires, rather 
 than just "noise" in the data.)

 So I encourage you to do more test runs with at least some of the 
 tires, and then do a statistical analysis. If you need help with that, we 
 can help. (BQ contributor Mark Vande Kamp has a Ph.D. with a minor in 
 statistics.)

 In the mean time, rather than looking at numbers, it may be more useful 
 to report your impressions of riding each tire. How did they feel 
 different 
 on each section of your course? Which one was more fun to ride? In the 
 end, 
 that is what counts for most of us when we ride.

 Again, thank you for doing the testing. Please continue the experiment 
 until you get meaningful numbers. It's of great interest to all of us how 
 these tires perform.

Jan,

You have discovered a way to make all tires seem supple and fast rolling: ride 
15 miles on rumble strips then go out on a "regular" ride. 
For those that don't want to spring for new tires!

Takashi,

First of all, I apologize for butchering your name...

Please do report on further testing you do, but I totally understand that 
testing is a tedious job. I can tell you when we did the rumble strip test, 
and I had to ride 15 miles on rumble strips over the course of a morning, I 
was glad to just go for a spin the following day on comparatively smooth 
roads.

We'll consider the Furious Fred and Thunder Burts when we next test tires 
on the track with a power meter under carefully controlled conditions. 
Thank you for the suggestion.

Thank you Jan.
I have enjoyed reading your articles in blog and BQ, and they inspired me 
to do the test.
As an amateur cyclist, my time to ride bike is limited, so I cannot say for 
sure how many times I will ride the same route.
I like to visit places I have never seen, rather than riding same route 
over and over.
(I'm pretty sure that most people in this group understand this inclination)
Still, I am interested in performances of tires myself, so when I do 
further test, I will post about it.

I have read in your blog (comment section maybe) that you consider Furious 
Fred and Thunder Burt as too much off-road-oriented, but I think they were

So I am expecting to read reviews of those tires in future issues of BQ.

Thanks for taking the trouble to test, record & post your findings.  The 
impressions are especially helpful. Oftentimes I find the subjective feel 
of how a tire rides & handles to be an important factor in my perception of 
the performance of the tire.  Good stuff.

[RBW] Re: Tested 6 pairs of 700c (29in) tires - results and impressions

2015-09-04 Thread Surlyprof
Nice experiment.  I'm surprised that the Mondial and Barlow Pass numbers 
were so close.  Like you, I always thought of my Mondials as a pretty slow, 
heavy tire.  The Barlow Pass Extralights felt light as the air inside them 
in comparison.  I would recommend the extralights.  I've ridden them for 
all my road riding this summer flat-free.  Unfortunately, my comparison is 
not nearly as accurate as yours as I use the Mondials on my heavier 
wheelset (32h Synergy with XT hub vs. 36h A719 with Phil Wood).  Now, if 
they would just make a Thunder Burt that fits a Hillborne, I could ditch 
the Mondials AND Smart Sams and ride one tire year 'round.  If anyone has a 
comparable tire in mind, I'm all ears.

Thanks for the write up.

FWIW, I've got about 1500 miles on my Furious Freds and the rear knoblets
are about halfway worn down; the fronts are almost as new. Probably 50%
pavement, 50% sandy dirt.

There are 3 types of Thunder Burts (LiteSkin, SnakeSkin, RaceGuard), 
whereas there is only one type of Furious Fred.

Just below photos there is a chart showing grip, durability, etc.
According to the website, TBs are a bit more durable than FFs.

Amazing, Takashi!

As most here know, my go to tires are: Thunder Burt for my Hunqapillar; 
Barlow Pass for my Quickbeam. I think you are on to something when you 
mention that heat could have been a factor with your Barlow Pass ride. I 
don't track speed, time, distance, etc., but hot rides are sure a LOT 
longer feeling than the same ride on a cool day. Throw in subtle 
differences in wind and/or precipitation, and even how you are feeling that 
ride -- It would take a lot of riders and/or very controled testing in real 
world circumstances to attempt to quiet down the "noise" in the data. To 
me, your ride impression notes are the most meaningful data you collected. 
Of the tires I've ridden, I concur with your assessment. Thank you for 
sharing this fantastic pile of personal experience with the tires!

With abandon,
Patrick
