After ordering these tubes I did lots of reading about how lightweight race tubes are horribly unreliable & require daily inflation. Nothing could be more untrue about these contis I got them as a set with Ultra Sport II Folding tires & I ride every day. The rim has bottoms out sometimes twice a day, and I dread a pinch flat each time it happens, but so far the tubes have held up lovely. I've begun stocking up on tubes & conti tires bc I think they have the best product & reputation in the sector.
This tube is nice middle weight folds up neatly doesn't weight much & isn't fragile when putting in when standing on the side of the road wishing you could hurry up and not be standing on the side of the road go ride!!
Been using this tube for years mostly with Vittoria Rubino Pro's with a fairly high PSI (110-120). I get pretty good milage out of these on my road bike, commuter bike, and track bike.
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.
The Continental Race Light Road tube is a fantastic tube and at BikeTiresDirect they are a very reasonable price. The Continental tubes are well made and long lasting for light weight tubes. Multiple rolling resistance tests show that the lightweight butyl tubes are within 2-3 watts as latex, but a lot less expensive. And, butyl tubes are safer to use in carbon clinchers due to their higher heat tolerance. The pressure loss of the Continental Race Light tubes is much better than any latex tube. The Continental Race Light tubes offer a great option for fast riding when the limitations of latex aren't worth the benefits.
