• 【Easy Install for Road Bike】: SPINGO TPU tubes match the 700c road bike tire size, check rim tape, and remove debris inside the tire. Slightly pre-inflate (max 0.5 PSI), insert the Presta valve straight, tuck the tube evenly (no twists), and mount the bead slowly to avoid pinch flats. Check both sides for any tube showing before inflating. Never exceed 5 PSI outside the tire. Need help? Message us anytime for support.
