Buy a handful of these when they go on sale. Light weight tube for easy riding or racing. Carry a spare and run these in all my bikes. If you get a thorn or flat these are ok to patch.
I may be a little lazy, but when I find something that works really well I tend to stop shopping. I've used these tubes with Conti GP4000S tires for many years with great performance and almost never any flats.
Does the job holds pressure nicely and never hurts to loose grams from rotating mass. Have 2 spare as well, recommend.
perfect for road and gravel riding. these are not puncture proof. as for standard tube, ready for action
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!!
I ordered the 60mm stem and they are ideal with the Roval CLX 50s!
Light and fast!
Solid performance, dependable tubes.
Great product keeps the pressure almost all week.
Touring and road riding in the city - lots of glass. tires have good puncture resistance yet light weight.
Nothing too remarkable, other than they work great.
The CB perfect inner tube
Safe choice among the lighter inner tubes.
Works great as a spare or main tire. I like using latex tubes for racings but these are my go-to spare because they are a bit more durable and can withstand some knocking about in the saddlebag or jersey pocket.
Great clincher tube with 80MM smooth stem if you have deep carbon race wheels and don't want to deal with stem extenders. Nice light tubes that just work.
Have used these Continental Race light tubes in 700x25 (Michelin) racing and training tires for several years. No problems. Stems work well with screw-on, shop and bike-mounted, pumps (Lezyne.) Sometimes I deflate slightly after ride, sometimes I just leave them at 110 psi. Doesn't seem to make any difference. (Although I still feel, from the old sew-days, that stretched rubber should be allowed to rest after a ride.) I would give it 5-stars except can't see calling any plain-ol' bike tube awesome and a steal. ,-
Very light but very fragile
I use these on all my road bikes and love them. They are light and reliable.
This tube helps offset the weight of the Continental Gatorskin tires, which provide the extra protection to enable an extension of this tube's life.
I purchased 2 of these tubes. 1 burst at only .66 miles into my ride and sounded like a firecracker! Seam split. The other held up for the ride but I may remove it. They leak air like crazy 20lbs over night. I will not buy these again.
