Tubolito Tubo CX/Gravel Bike Tube 2-Pack with Repair Kit – 700c x 32-50mm TPU Inner Tube, 60mm Presta Valve, Fits 650B – Lightweight Puncture-Resistant Gravel & Cyclocross Tube

• TWO TIMES STRONGER, HALF THE WEIGHT – This TPU gravel bike tube weighs just 61g yet delivers double the puncture resistance of a standard butyl inner tube, so you can ride rocky, thorny gravel and cyclocross courses with confidence and without added bulk.
• 2 TUBES + FULL BIKE TUBE REPAIR KIT INCLUDED – This bundle includes two 700c x 32-50mm TPU inner tubes with a 60mm Presta valve, plus a Flix Patch repair kit (patch strips, Camplast adhesive cement, and alcohol prep pads), so you're always ready to fix a flat and get rolling again in minutes.
• 60MM VALVE FOR DEEP-SECTION RIMS – Built with a longer 60mm Presta valve, this tube reaches through deeper gravel and cyclocross rim profiles that a standard 42mm valve can't — no valve extender needed.
• FITS 700C & 650B, 32-50MM GRAVEL & CX TIRES – Purpose-built as a gravel bike tube and cyclocross tube in one, this tube fits tire widths from 32mm to 50mm and works with both disc brake and rim brake wheels — one reliable spare tube for nearly every gravel/CX setup.
• POCKET-SIZED FOR LONG RIDES – Rolling down to roughly half the packed size of a traditional bike tube, it slips easily into a jersey pocket, saddle bag, frame bag, or bikepacking kit, so you always carry a dependable backup tube on long rides without the extra weight.
