[RBW] Re: Challenge Tire Woes and 700x30 options

Ditch the latex tubes and keep the tires.  I really like the SBs and as 
soon as I chucked the lot of latex tubes that I bought, I began to enjoy 
the tires even more.

try them with lower pressure - down to 60 psi rear.

The real kicker is a have an extra Open Pro wheelset laying around and, until 
this mornings frustration, I wanted to set it up as second wheelset for my 
Custom with Strada Biancas for fast pavement use.  12-28 with Strada Biancas; 
11-30 with Almanzos.  Or maybe vis a versa? Every boy's dream.  I'm a 
sucker---I'll still probably do it.  Argh.

answering out of turn, I'm 6'3', 210 lbs, and was running 30mm Strada 
Biancas at 65 psi rear, and 50 psi front, but could drop them lower for 
gravel.

I'm running Open Pro rims with the Challenges at 60-75 psi.  Does anyone have 
experience with Michelin Jets, on and off pavement?

 As far as a tire 28mm Panaracer Gravel Kings come to mind.  From what I 
have read it seems they are about 28mm actual on narrow rims and 30-31 on 
wide ones, likely meaning 23-24mm rims. They also have a 32mm version but 
that may be to much for your bike.

Hi Jay, my experience with Challenge is the bead stretches out before the 
tread wears out.  I gave a set of Stradas from my daughter's bike to my 
buddy a couple of weeks ago - he and his daughter were rebuilding a 
frankenbike Shogun and these were the largest tires that would clear the 
rear brake.  When we met for a ride Sunday morning, sure enough, the bead 
one of her tires at 75 psi had let go in transit.  We got it back on the 
ground with a new (butyl) tube and 70 psi, and she rode 25 fast miles.  

In thousands of miles on Challenge, I've never experienced glue failures, 
and I know others have - though I did have a P-R tubie with a glue holiday 
that was replaced under warranty.  


Also had a casing defect on a Chicane tubie that failed 2 miles out on a 
maiden ride.  



both were handled as the warranty by the vendors.  


My experience is any sizes of the "open tubular" clinchers is they work 
best on skinny rims and running well under rated pressure - which they do 
quite well, both comfort and speed.  I've run 30mm Strada Biancas on two 
bikes for many thousand miles, Open Pro and Synergy rims.  I never had a 
bead relaxation problem on the Open Pros, but finally changed those to 
Barlows just because they would fit.  FWIW, the Strada Biancas ran 
wonderfully at the same (low) pressures as the Barlows.  On the Synergy 
rims is where I really noticed the bead relaxation became habitual as the 
tire aged.  I finally gave up on those and went to Stampede Pass EL (with 
latex tubes) and find them nearly as fast and notably more cozy because of 
the taller sidewall.  


Currently I'm not running Challenge on anything.  My go-fast has 27mm 
Vittoria Open Paves, which are wonderful in every respect except the soft 
tread wears out.  

My daughter had a maiden ride on Veloflex Corsa (only available in 25mm) 
last weekend, which are actually the same tires as the Open Paves, but 
hand-made in Italy and about 20% cheaper.  She was delighted.  I also run 
the Vittoria/Veloflex open tubulars well below rated pressure.  


One tire you may want to try is the Vittoria Cross XN, which has a killer 
price at Wiggle right now.  If they're like all other Vittorias, they're 
narrower and taller than width rating would indicate.  I was strongly 
tempted by these at higher price before I went to the Barlows.  

http://www.wiggle.com/vittoria-cross-xn-pro-folding-cyclocross-tire/ 
currently OOS, I would put an e-mail stock notification - that's how I 
managed to catch veloflex for my daughter - they sell out quickly when they 
show up in stock.
