used them for a particularly challenging century (9,000 ft of climbing) and noticed (and welcomed) the difference
Tubeless! Disc! Aero! Blah, blah blah. Cyclists should wear wool shorts (BLACK), a jersey with a single sponsor, a cycling cap, and ride a Columbus-steel bike with a set of Continental Grand Prix and Conti tubes around Mavic hoops with 32 spokes. It's how things are supposed to be - not all this newfangled shiny plastic trash.
Even if you have succumbed to the lure of the modern, grab these - they'll last, they'll fill with air, and the spare will fold nicely into your jersey pocket.
Super long lasting tire
Awesome !
Great inner tube. No problems. Long lasting. Durable.
Switched from Kendas because Kenda tubes kept splitting at the seam.
When paired with Conti 4000 S or Grand Prix these tubes noticeably improve ride quality compared to standard tubes. They just feel lighter and softer, but are still durable enough for training, steer clear of the Supersonic tubes, they have a tendency to explode for no reason.
Great dependable tube for race day or training rides. I installed them on my bike one day before a race and they performed wonderfully.
I like tubes with long threaded stems and this fit the bill. I don't know why tubes cost so much, but this one works well and is easily reparable if you get a flat. I prefer the threaded tubes as they seem to hold better on my floor pump valve head.
Lives up to its billing as a lightweight tube. Use this when weight is at a premium like when I'm doing hills and centuries. BUT, these are delicate. Need to be extremely careful when mountingdemounting tires. Very easy to pinch holes with the tire levers if you are not careful. Holds air reasonably well. Loses about 3 lbs per day. Losses slow a bit with age. But, nowhere near the lower rate of standard heavy tubes.
After going through 4 Continental Supersonic Tubes (super light weight) in a month, I recently opted for the Conti Race Light tubes. These tubes fit in the middle,weight wise, between the supersonics and regular tubes and have held up well and are lasting longer than the supersonics (but see hints below). I feel that they do give me some advantage through less rolling resistance from the regular tubes but not as much as from the Supersonics. I love both of the lighter tubes especially when climbing, feeling there is a big difference in my speeds as I climb and crest hills than with the regular tubes. Hints 1)always use talc when putting these in to avoid pinch flats and 2)if your tires are not new and have little cuts through to the inside which are abrasive on the tubes....cover these on the inside of the tire with a flat boy patch or some other equivalent...all the flats that I have had with the lighter tubes have been pinholes from such wear...they would get me through the ride but the next morning they would be down to 40psi or so. Next time I buy a new set of Conti GP 4000s tires I will try the Supersonics again and report back as to durability in a new tire.
Have used in the past with no issues.
Very few 80mm choices out there but the Race 28 Light was the best choice I've come across. Fairly light, for what it is, at about 80 grams and at this price point makes it a good value especially with the quantity discount. After using them for about a year in a variety of temperatures on normal roads they hold up very well. Nothing negative to report.
Bought these to go in my new GP 4000 tyres. No, I not English - just having fun.
I use this tube along with a set of Continental 4000S tire and Mavic Elite rims to make a nice light weight set up with out breaking the bank.
Average tube, good brand.
When paired with the GP4000S, this is 1/2 of a go-to setup for training. You may (or may not) want to switch to a latex tube on race day but remember, try it in training first. You may decide it's not worth the effort to change it out!
I've gone the extreme route before, shaving off every gram of every product I buy. The result was an unacceptable amount of time on roadsides repairing flats. So far (maybe 1000 miles), no flats on our bumpy Central Oregon chip-seal roads, where one always has to keep an eye peeled for the remnants of beer bottles tossed by folks that mistake the open road for a recycling bin. I like the weight saved, and I like not changing flats, this tube seems like an excellent compromise.
Paired these tubes with 700x23mm Conti 4000s tires, the combination is mounted on HED Ardennes FR clinchers and I'm a happy man. Great ride, good road feel, finishing the rides feeling fresh and so far No flats! I would recommend this set up to a friend.
Recently moving to aero wheels on my tri bike, these are a great deal and the 80 mm stems make them easier to deal with than valve extenders. They can be sticky coming out of the box so I recommend a little talc powder before putting them on.
