At 70 I'm not racing anymore, but still do some fast group rides, I have been using Michelin tires for 20 years
These Power competition tires are fast, they help me hang on with less rolling resistance , a must have for anyone wishing to ride faster.
Love these tires! I have used all early versions of the pro race series and the competition is by far the best. I used to think the Vittoria open Corsa was the fastest feeling tire but I way the competition rolls better...and it is super smooth. I have athese in a 25c on Enve 3.4 wheelset with a BMC TEAMMACHINE!
The day after I ordered these tires, one of my riding buddies told me he had two sidewall cut incidents in a single week while running the Power Comps. Thinking (hoping) that was just bad luck, I installed mine and was really pleased (smooth, fast, great cornering) but then, 10 days later-you guessed it-I flatted and upon further inspection discovered a 1.5-inch cut in the sidewall. Three (irreparable) sidewall cuts in 3 weeks by two different riders tells me something's wrong with these tires. I can't recommend them.
Used one week approx 185 miles in fast group rides plus recovery days, there light and fast you can really feel the difference in watt savings over the pro 4. there race tires so i don't expect super milage.
These tires rock so far helping a 70 guy keep up
No flats on bad jersey roads. The ride is supple not squishy.
Also makes the the tires make my Mavic Carbon wheels look nicer than the stock Mavic tires.
I have ridden them for about 400 miles.
For use on my Felt Z85. Original Felt tires lasted 1600 miles. I have 500 miles on the newer Michelin set now. Rear tire cutpunctured last night - first flat this year. Ordered another - because are just so much lighter and quicker accelerating..perhaps trade-off is puncture resistance. These are prolly meant for race only, no debris conditions...2100 mile on the bike this season so far - loving it. Next step, better wheelset.
Piled on about 2500 miles on a set of these and it's time to replace. I think I only flatted twice on these during that time and I ride some pretty crappy roads, so I'm pretty happy about that. $65 a tire doesn't make me happy though. Debating on trying the Endurance version this time around.
Bora One 50mm carbon clinchers - no issues with mounting etc.
Decided to break out of my usual yearly gp4000 order and am writing this stranded after about 200 miles on the tires (had two tubes). They are fast, feel great around corners but are not strong enough for where I ride it seems. Recommend for smooth pavement. Will probably keep the fronts on but order another continental for the rear.
