In January, after dealing with over 40 flat tires on this trip, we purchased Kenda Thorn Resistant Tubes and had our friends, Cait and Mark, deliver them when when they visited us in Belize.
Overall impression of the Kenda Thorn Resistant Tubes: FAIL
Three of the five tubes we purchased have failed at the valve stem. The valve stem separates from the tube rendering the tube flat and useless. A quick search on the internet reveals many other reports of similar valve problems. To their credit through, they have resulted in less punctures, so they live up to their name. But there’s something clearly wrong with the valve attachment.
The third one broke today as we were leaving Cajamarca. This meant were were down to one spare tube between the both of us. Anticipating that the remaining two Kenda Thorn Resistant Tubes will likely fail we decided to pick up two more tubes before leaving the city. Easier said than done. Our wheels take tubes with a presta valve. Tubes with a schrader valve (like care tires) will not fit through the hole in our wheels.
We ride around the city for hours looking for a bike shop that has tubes with presta valves. It seems all anyone has are tubes with schrader valves. We stop at an internet cafe to check the googles for info on bike shops in Cajamarca. It’s slim pickins but Scott finds a blog from another bike tourists that mentions a shop with good inventory.
We arrive to find it’s closed for lunch. After about an hour the guys return and sure enough, they’ve got what we need. In case you’re ever in Cajamarca and need a bike shop, we recommend the Kawasaki Shop on Progresso 627. It’s a combo bicycle-motorbike shop, on the south side of town. The staff are nice and helpful.
We finally head out of town at 3:30pm. The sun sets in less than three hours.
We make it 25 miles and make camp in a field of eucalyptus trees. Their strong scent reminds me of craft stores back home. It smells like we’re camped inside a Hobby Lobby. I read that the scent of eucalyptus counters physical and mental fatigue. I’m considering strapping a tree to our bikes, or at least a branch to my helmet.
