BOOM. that is such good advice. I am always surprised when I have quick flat change. I do it once a year at most so its hard to be good at it. if I really cared, i'd practice it like I practice T1, T2, and everything else.

Yep that the recommendations so that's what I'm going to do....

Similar puncture resistance to the Conti 4 Season, but the Pro 4 Endurance only suffers a 2 watt per tire disadvantage (@ 18mph) to the GP4000SII while the 4 Season costs you ~5 watts per tire. The Gatorskin is over 7 watts a tire, nearly 15 for the pair.

"They're made of latex, not nitroglycerin"

Friends don't let friends race on Gatorskins....ever. Puncture resistance with latex tubes and sealant of GP4k are more than adequate for racing or training. Plus if you flat a gatorskin, they are not easy to get off and reinstall. GP's go on and off pretty easy.

Gatorskins are nice for training in cold climates because they slow you down. Less forward speed = less cooling effect.

Why now train on one set, race on another? A worn tire has worst aerodynamics and all the cuts and damage from training makes a tire riskier for racing an important event.

Everyone hates flats. It can ruin a ride. I average a flat about once every 1500-2000 miles or so outdoors I'd say. That's maybe 2x a year. I ride about 60/40 annually indoors vs. outdoors I'd say.

Hi...thanks for your info. It's unanimous and I'm heading to 4000's for sure as soon as I'm off the trainer because of snow! I ride Zipp Firecrest 404's and have decided 25's are my best option. 28's seem too wide and I'd end up taking a speed hit....

This is the first mention of sealant in the thread, is there a preferred sealant for a bike that sees both training and racing?

+1, best option.

Terrible option!

I enjoy riding. Nice tires make riding the bike feel much better, both physically and because you don't have the knowledge you're being compromised by sluggish tires. I don't just train to race, I also train to train. I'm not going to accept a less comfortable and enjoyable ride on every ride accept when I'm racing, based on an irrational fear of punctures and in the hope I can trick myself into greater motivation during the race. I'll enjoy my bike thanks!

+100000 I don't know why ANYONE would ride gatorskins. They suck, period. And they're way more expensive than GP4000s. I have never seen them on sale. I have looked for them as a trainer tire but they are always at MSRP where I can get a GP4000 for like $35 anyway.

My fear of flats wasn't irrational. Happened often in the Contis. N=1, as always

Gatorskins for $28.00

Not saying that Gatorskins provide the same ride as 4000s. But the do last like iron.

I stand corrected. I haven't looked in a year or two since I have just been using my 4000s. I don't want to put a number on the tires but I have used the same tires for a few seasons I think. When they get too worn for outdoors I put them on in the winter for the trainer. So for the price it's not like I am only getting one season of use. They used to be race tire, then training tire, then trainer tire. So they get a good beating from me!
