Continental Grand Prix 5000 Performance Motorcycle Tires - Set of 2

Very good tire.

Continental GP 5000TL 700x28c Additional note: After 1,000 miles the tires show very little wear so I increased the rating to five stars. I've also settled on 75 psi front/80 psi rear. This review would have been five stars if I had more experience with tire mileage. With only 300 miles on the tires I can’t comment on expected tire life. I can say the rear tire mold flash has finally worn off while the front tire still has some mold flash. My neighbor also changed from Hutchinson Sector 28 to the Continentals and agrees with my findings. The following comparison is between the GP 5000TL tires and Hutchinson Sector 28 tires. These are the only two tubeless tires I’ve ridden on. Riding Experience 1. Quieter. While bike tires aren’t especially noisy, the Continental tires were noticeably quieter. 2. Smoother ride. The Hutchinsons were harsh over the very bumpy roads in my area. The Continental tires are much smoother. I have an annoying rattle from the Di2 components that was very harsh over bumps and alligator pavement. With the Continentals the noise is much less and not nearly as annoying. 3. Somewhat more stable. The Continentals exhibit a bit less road steer and are a bit more stable over uneven pavement. Not a big difference but still noticeable. 4. Less rolling resistance. I have no way to measure this characteristic, but the Continentals seems to offer less rolling resistance. Judging from some hill climbs, I would judge the effect to be perhaps a half-gear improvement. Determining any improvement in rolling resistance is difficult without proper equipment (plus not knowing which legs will show up. Sometimes it’s the used-to-be-36-year-old legs. Sometimes it’s the you-really-are-getting-old-73-year-old legs. And sometimes it’s the Ghost of Cycling Future 85-year-old legs.) but the pedaling effort does seem to be less. Mounting Comments Three out of four tires seated with a hand pump. One tire needed an air compressor the first time. I found the following process to work well: 1. Mount and inflate the tire without sealant. 2. Deflate the tire. 3. With the tire valve at 4:00 or 8:00 dismount about six inches of the tire at the bottom, enough to easily insert the sealant. 4. Using Stan’s “The Injector” or a similar device, inject 35ml sealant (I use Stan’s Race sealant) into the open part of the tire. 5. Slowly rotate the tire so the open part is at the top. Valve should be at 10:00 or 2:00. 6. Remount the tire and reinflate. 7. Spin the tire per instructions to distribute the sealant. 8. Go for a ride to complete the seating and sealing process. Tire Pressure Combined weight of rider and bike = 182 lbs. I started with 85/F and 90/R and worked my way down to 70/F 75/R. Those pressures give me the best combination of ride comfort and pedaling effort. Pressures above 70/F made the front tire much too bouncy. My neighbor (10 lbs. heavier) uses 75 for both tires. Tire Circumference Continental indicates a tire circumference of 2155 for the 700x28c. My measurement showed a circumference of 2142. Comments I’m not claiming that the Continental GP 5000TL tires make the bike ride like a Bentley and handle like a Ferrari (I’ve never ridden in a Bentley or driven a Ferrari) but they are very impressive tires. And if you are still debating going tubeless, my experience with almost 5,000 miles on tubeless tires has been very positive. With the few flats I’ve had, the tires always sealed and I was able to ride home safely.

The tyres didn’t came on the original boxes!!! Really disappointed

Disclaimer: I put these tires on brand new wheels so some of the awesome is due to the also excellent Hunt wheels. Mounting: These tires went on the rims easier than some other tubeless tires I've had. A lot of people have had trouble with this. In reading the reviews I noticed a common thread. The majority of people having difficulty were putting them on Mavic rims. Mavic says that using other brand tires on their UST rims "can be harder to use or unsafe." These tires went on the rims with no tools or lubricant. They seated on the Hunt rims with just a track pump, no compressor or CO2 needed. I took them for a quick 10 mile ride with no sealant and they held pressure perfectly. Ride quality: fast and smooth. I went from 25mm to 28mm and from 90-100psi down to 65-75psi. I was a little skeptical that wider tires with much lower pressure would be as fast, but if anything they are faster. The ride is smooth with the lower pressure really soaking up the road jitter without feeling at all mushy. Handling: very planted in corners, no worries about absolutly ripping tight curves. Wet braking is very very good. I did a test panic stop in the rain and I was able to get the front tire right to the threshold with no fuss. Disclaimer: disc brakes do help a lot with this. Durability: I can't speak to this because I only have about 100 miles on them, but judging by how the mold flash on the centerline of the tire has held up I don't think there will be any issues. I also can't speak to puncture resistance for the same reason, but I almost never get flats running tubeless anyway. I'll be really surprised if I all of a sudden start getting flats with these tires. Unless they wear horribly or get a ton of flats I'll almost certainly buy them again once this pair has given their all.

Great quality!!!
