'Dale Posted June 17, 2014 Posted June 17, 2014 Is that a carbon wheel with carbon brake surface? Take care, from Zipps support page Yeah, Cosmic Ultimates I lightlylightly sand my brake pads when I swop over to the tubbies, to eliminate any bits of alu. GoLefty!! and SwissVan 2
SwissVan Posted June 17, 2014 Posted June 17, 2014 Yeah, Cosmic UltimatesI lightlylightly sand my brake pads when I swop over to the tubbies, to eliminate any bits of alu. Ok that's a good plan, I assume it works? Anudder question Darren...related to swopping race wheels and training wheels (rear) with Di (electric gears)How well do the gears work if u swop a wheel, do u have to tune the Di brainbox before riding again?Assuming that the Di brainbox servo is tuned to the first wheel and not the second wheel
Johan Bornman Posted June 17, 2014 Posted June 17, 2014 Yeah, Cosmic Ultimates I lightlylightly sand my brake pads when I swop over to the tubbies, to eliminate any bits of alu. Sanding it doesn't work. The alu bits are about 1mm in length and penetrate deeper than you can sand. The best way to get it out is with a sharp pick. I used to show this technique to the students in my class in the Sunday-afternoon-yawn session on maintaining caliper brakes.The secret to avoiding this irritation is to use Koolstop pads - Salmon colour. These have a patented rubber compound that no-one else uses and it works. I think the patent has another 4 or so years to go before it expires, then you'll see everyone's brakpads turning dark orange from the FeO2 on there. GoLefty!! 1

Thanx, JB Nice tip there about the Koolstop brieke
kennyg Posted June 17, 2014 Posted June 17, 2014 I can put a spanner in the works... I have tubular clinchers... Tubby tyres that mount to clincher rims, yes they work pretty well, it will help make your decision to go pure tubby or not.
Spinnekop Posted June 17, 2014 Posted June 17, 2014 Also the classifieds have alot more carbon tubbies than clinchers as well and cheaper but yes I know tubbies are more expensive but do you really go through a pair that often? 4 races. 4 cut tubbies.Bad luck I suppose. But that was the end of that. Went clinchers and never looked back! Have been racing with the Vets for 7 years now

Bianchisti Posted June 18, 2014 Posted June 18, 2014 I rode tubbies for 5 years and never punctured when I lived abroad. Well I punctured but the wheel takes forever to deflate and that’s plenty time to get home. Next day I just put new air in it and off I went again. I only put sealant in it once when it deflated too quick and the tubbie was good to go for months again. Moved back to SA and I punctured every week, and the air was gone in seconds because of glass pieces cutting the tyres. Bought a set of clinchers after a month to train with. Them too had cuts after a few weeks. It might just be the roads I took. So in SA I will ride tubbies only in races, because unless the tyre explodes it will usually get you home before it completely deflates. I’m temporarily abroad again at the moment and I’m training on my tubbies (lighter to travel with). Not one puncture in 7 weeks. Sometimes I carry a spare tubbie in my back pocket though. If you puncture you can still replace it on the road with no glue. The air pressure will keep the tyre secured to the rim. Just don’t go cornering hard or at crazy lean angles.
kennyg Posted June 18, 2014 Posted June 18, 2014 TUFO very nice if a little bit weighty Not too bad, in line with similar clinchers, but a very quick easy to use tyre.
Mavro Posted June 18, 2014 Posted June 18, 2014 (edited) Got rid of my clinchers last year September. Since thenI only ride with tubbies. Have not regretted the switch. In approx 8000km's I picked up 3 punctures. Two of those punctures came from tires that were worn out. After close inspection I could see tire carcass coming through the rubber. The other puncture came from the conti giro tubby. I do not recommend that tire as my experience was it is not a positive. I currently use gatorskin sprinters and I am happy with them. I don't use any sealant. Don't understand why people are so afraid of tubbies. Count how many times you puncture a year. That number you can probably count on one hand. I strongly recommend switching to tubbies. Edited June 18, 2014 by Mavro 'Dale 1
