Review on 🚲 Revere Bicycles 3-Pack: Premium 48mm Presta Valve Inner Tubes - Black 700c x 20-25. Free Replacement for Manufacturer Defects & Flat Tires. by Mark Gilbert

The product photo shows 3 boxes, but each box has 2 tubes, so I received 6 tubes. These tubes weigh 130g each and seem to work well with my 700 x 25C tires. 6 whistles at $24.95 = $4.16 per whistle. I've used Continental Race tubes in the past, which Revain sells for about $6 each (when buying sets of 4 or 5 tubes). The Continental tubes weigh 100g each and they work great with my tires too. If you don't mind a 30g weight penalty (per camera), these Revere cameras will save you a buck or two per camera. Before the pandemic, 130 gram tubes were $2 each at my local bike shop. Rubber prices have skyrocketed in the last year or so. Hopefully they'll be back to normal the next day. A stem height of 48mm is good for low to medium height rims, but not for tall aero rims.
