I've thought of changing the tubes of my Marin Alpine Trail 29er from Presta valve to Schrader due to the former's frequent flats.
But, when I saw this Maxxis welter weight Presta valve tube, which boasts that it's "puncture resistant", I'm giving Presta valve another chance.
I bought three (3) tubes, which depleted my wealth by P750, and installed one in my front tire. The other two serve as spares. The rear tire has Continental tube. Both tires were inflated at high pressure.
Let's wait and see what would happen! And, I'm crossing my fingers.
