We all love to stop and smell the roses, but like they say, every rose has its thorn. And as we all know, there's no better way to ruin a beautiful ride than with a thorn in the tube. No need to worry, though, because we designed our Thorn-Resistant Presta Valve Tubes to combat pesky pricks of all shapes and sizes.
Starting at the basis of the construction, we designed the tube to be thicker at the outer side (the part against the tire) in order to stop pesky bits from puncturing all the way through the tube. Then, at the inner side (the part against the rim), it's actually thinner in order to reduce weight. This way, you don't have to sacrifice performance in the name of protection.

I appreciate the delivery status updates and on time delivery. Sierra had a part for my Route Werks Handlebar Bag that I needed quickly and without costly shipping charges. Much appreciated!
costs a bit more than the entry level withings scale we tried (purchased elsewhere), but oh my goodness, setup was sooo much easier, and the display is worlds better. the app is the icing on the cake, no up selling for extra subs, just "here's your data" and done. stumbled across Sierra by chance, and was impressed with their process from start to finish.
bike perfectly set-up! Just put the final touches together, charge & ride!
Fast shipping. Good communication. Great discount. Easy payment. Excellent product.
