There are few tubes in the 650c size which is used on some road bikes. This tube, from Continental, offers light weight and low rolling resistance but ample durability for continuous use.
I have only had a blowout with this tube once which was when both the front and rear tires suffered pinch flats at around 100 psi. The city of Dearborn had not yet noticed a giant pothole near a school and it was a disaster for road bikes.
As far as usual flats, i have had only a few in many thousands of miles of riding and racing..
650c is harder to find these days, so good to have a source. Conti makes consistent quality tubes that install easily, and come out easily. No adhesion to the tire walls to make matters complicated.
Received as advertised and fast shipping. Thank you.
I get these tubes when their on sale. I get any tube that's on sale. No slime tubes. What can I say? It's a tube.
I love it?
I use my bicycle primarily for suburban and city commuting, doing an average of 90 miles per week and replace about one tube every 3-4 months, due to punctures from glass, staples and other sharp objects. I do ride with patched tubes for as long as I can get away with it. Durability depends on the amount of construction and other debris in parking lots and on the roads I ride, which varies seasonally. These tubes have proven more robust than any of the others I have tried.
It's a tube! It does everything a tube should do, and does it well. To me, it represents a fair compromise between weight and durabilitypuncture resistance. I like the choice of valve lengths because I saves me from using expensive and troublesome extenders. I've never had an issue with one of these tubes, so by default it has become my go-to tube.
One of few lightweight tubes available inj 559!
Strong tube. No issue
No issues with install or usage. Held up great in my race.
It popped pretty quick, but my tires were worn so it wouldn't be fair for me to blame it on the tube.
Racing tire for my time trial back. Seem to last a long time and holds up on the road and on the trainer.
These tubes are super thin and if you look at them the wrong way you'll be putting a hole in the tube. Unfortunately in the 650 size there are few options to choose from.
The tubes are easy to install and I have typically had good results with Conti's tubes but for some reason, had three or four flats in rapid succession with these. It may just be the time of year with lots of extra debris on the roads. I have loved their 700c tubes and don't see any reason why their 650s would be different.
tubes are used on my triathlon bike. Over 1200 miles without a flat on these tubes. Great product.
It's not easy to find 650 tubes anymore! These are lightweight, yet still hold up to everyday use.
Paird with the Gatorbacks and Zipp wheels my confidence grows with each outing.
