RUTU 24 inch Bike Tube 24x2.125/2.40 Bike Tube AV32mm Schrader Valve Compatible with 24x2.10 24x2.125 24x2.20 24x2.30 24x2.40 Bike Tires 20" Bicycle Tube with Tire Levers 2 Pack

Kids mountain bike had a hole in the tube near the valve. Bought these to replace their damaged one. My 10 year old replace it himself so it was easy to install. Quality and price was good.

The media could not be loaded. A pair of 24/2.125 size tube fits to my son's mountain bike with the same spec really well. The kits come with 2 pry bars and 2 extra fancier caps and some valves. The only thing I need to prepare is the wrench to unscrew wheels and doing some research how-to. Everything works smooth and end result is just fine. I have pumped air and leave over night and it seems still very solid and not leaking anymore. It's a good DIY bicycle tire tube swap kit.

Not much I can say about some bike tire tubes. The fit is exactly what was advertised and all the extra accessories were nice. I actually used them and replaced the stems in my kids bikes. So far no issues and we’re not necessarily easy on our bikes.

Great tube replacement for my kids bike. Easy to install, fit properly and inflated with no issues and it’s not loosing air. I like the extra valves etc that come with the kit. I only needed one tube but now I have a spare one incase my son blows his other tire so for me it’s been good value.
