Great tube to carry on the trail for unexpected flats. I use a voile strap and keep one attached to my bike any time I'm doing a longer ride. They are also quite a bit cheaper than other alternatives and seem to be just as good.
Continental makes great products and this is no exception. These tubes hold up to abuse and are less expensive than many other options that are very similar. If you are looking for an extra tube to carry along on your ride these are a great choice.
I run all Continental tubes in my road bikes and knock on rubber I haven't had any issues in my thousands of miles of use, so when I needed a spare tube to run on my MTB in case of a failure this was the obvious choice. Thankfully I haven't needed to use it.
I grab these to have in my pack on the trail. I ride with Tubeless wheels but its always nice to know if there are any problems i am covered, I have used several of these in the past and the hold up great . Inexpensive and necessary when riding out on a distant ride. Grab a bunch!
Familiarity: I've used it once or twice and have initial impressions
In 2017 not many folks ride with these heavy, fragile things in their tires. However, pretty much everyone has one either strapped to their frame or in bag in case of emergency. My favorite part about bike tubes is that they're one of the only bike parts you can just buy whenever you want without checking your bank account first. Makes me feel like a real baller.
