ZIP 404 tubulars - carbon peeled off on tire

I raced a sprint tri yesterday on my new ZIP 404’s. Used only once before at IM Kona '04.

Got a flat on the 2nd loop of the bike leg, immediately stopped and changed the tire. Lost near 5:30 on the tire change (did a good glue job on this one!) but managed to get back for a 2nd place in AG…but…

…got home and checked out the punctured tire and there is 6+ inches of carbon stuck it to. The carbon fsbric on the rim valley and edge/lip has failed, appears to be insufficient resin, or partially saturated carbon fibres. There are small cracks on the lip/edge of the rim too.

Any one expereinced this type of failure before? What is the warranty like. These are less than 2 months old, used twice!

Thanks,

Mark

Hope you didn’t use 3M Fast Tack glue. I know its not good for tyres. Maybe bad for the Rim as well.

Cheers!

Nope, saw the repeated warnings on ZIPPs gluing instructions re 3M auto glue. I used Pana Cement by Panaracer.

wow that’s a new one, I’ll pulled base tape off my tires but never Carbon off my 404s. What kind of super glue did you use:) I’m guessing Zip will cover this no problem but that’s just a guess. I’ve never seen any of the 404s at Gary’s and that’s a lot of 404s, peel like that before. Nice race though, thank god I’ve never had to make that change in a race yet. But just think, if you’d been up there off the bike you would have gotten lost with us on the run too:)

Tai,

Used Pana Cement. Took a lot of effort to remove the tubular. My fingers were cold and twicthy coming off the swim. For my very first tubular glue job, maybe I did it too well!

Took it back to IT&B and Chad and Jason had never seen anything like it either. They think ZIPP will cover it and maybe comp me a new tubular for the inconvenience.

I loved that run yesterday - but trashed (ie dirty) the Saucony Swerve’s. I will drop by and get a pair of Fasttwitch Endurance for the Honolulu Marathon soon. I noticed you were wearing Fasttwitch - Speed I guess, since you had the fastest run split of the day. Well done.

Also, why was your overtime about 1 minute faster than Jay Paul’s when you two crossed the line about the same time?

aloha, Mark

Hey Mark, my time was 1 min faster than Jays?? Maybe that explains the run split or maybe they penalized Jay for not telling me I was going the wrong way down the beach:) I would say that’s why my run split was so crazy fast. I came into T2 maybe a minute-minute thirty down on Jay and caught him before the beach then he got maybe 45 s in front of me when I didn’t turn off the beach at the right place.

It’s better to do a good glue job then a bad one. At the state crit this year a girl rolled her front Zipp 303 and it didn’t look pleasant. Two other girls who went down with her went to the hospital. I use Panaracer as well, conti and panaracer are the nicest. Don’t buy that Hutchinson crap from IT&B. None of the guys there use tubulars or they’d have figured out how terrible it was. I borrowed a 404 set for Ko’olina and the guy who had glued the tires on (will remain nameless to protect his identity) had put so little glue I rolled them off in 5 seconds or slow, thank god I put on my own tires…

I used the Fastwitch Endurance. The speed are nice and more responsive but they don’t grab at all on anything wet:( almost went down at Ko’olina on some of the wet concrete. The Endurance is a blown rubber forefoot and grabs rock like velcro.

Tai,

On Friday before IM Kona I was at HP Bike Works and Darrin the bike techie was there with a girl customer who had a nice black Specialized bike. Darrin was explaining that he had to replace the tubular tires because the glue job was real spotty and generally dangerous. It had IM Kona race #1 on it. It was Peter Reid’s bike.

Re your Haleiwa Tri time. Steve apparently did a manual override of your chip time because it was a fraction of a second between you and Jay - but he accidentally deducted 1 min and 1 sec rather than 1 sec from your time. Mystery solved!

Damn wish he deducted 5 minutes off my time! :slight_smile:

IMHO, trusting someone else to glue your tubulars is like trusting some to pack you parachute for you. Nothing beats the extra special care you’ll give yourself.

Not sure if you know Matt Simpson, former US national road guy, lived here for a while and was back here volunteering with Darin at IM. I heard that story from him about Peter’s bike and and even scarier one from years past. This was another former Kona winner but since I’m not 100% sure of her name I’ll hold that back. She came in complaining of a bump in her carbon tubulars, it went bump bump bump as she rode it. Matt said that the tire had NO glue on it and except for the valve stem the entire tire had turned inside out and she was riding on the BASE TAPE. The bump was the base tape overlap…
