They're good quality, value-for-money inner tubes, well-made with good valves and hold their pressure well. I generally add some Slime or Goop before inflating to provide additional puncture protection and never had a problem despite mostly riding on rough ground and canal towpaths. Wouldn't hesitate to buy more. Review: Its an Inner Tube. What can you say? - The product arrives in record time. Sadly it was the wrong one. One email to the supplier and the correct replacement was posted the same day and arrived next morning. Fitted onto bike in moments, and after a month of hard use is still working fine. Cant say much other than great service, fast delivery and it does its job. No idea if its cheap or not but getting it was hassle free despite getting sent the wrong one initially. Top service and good product. ## Features - Inner Tubes - Brand New - Boxed - Quality Guaranteed - Made from the best Butyl Rubber - Fits Most Popular kids bikes, including small mountain bikes and all BMX's - Will fit: 20 x 1.75 20 x 1.90 20 x 1.95 20 x 2.10 20 x 2.125 tyres - Standard Schrader Valve (car type) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0046A1S1U | | Best Sellers Rank | 163,961 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) 1,543 in Cycling Tubes | | Bike Type | BMX Bike, Mountain Bike | | Brand | Sunchase | | Brand Name | Sunchase | | Compatible Tire Width Maximum | 54 Millimetres | | Compatible Tire Width Minimum | 42 Millimetres | | Customer Reviews | 4.4 out of 5 stars 585 Reviews | | Item Diameter | 20 Inches | | Item Weight | 159 g | | Item diameter | 20 Inches | | Manufacturer | Sunchase | | Manufacturer Part Number | unknown | | Material | Butyl Rubber | | Material Type | Butyl Rubber | | Size | 20 inches | | UPC | 793740699985 | | Unit Count | 1.0 count | | Valve Type | Schrader | | Valve type | Schrader | | Wheel Size | 20 Inches | | Wheel size | 20 Inches | ## Images ![Inner tube 20" x 1.75-2.125 - bicycle inner tube - schrader valves - Image 1](https://m.media-amazon.com/images/I/61w0uJX1lVL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good value inner tubes with secure valves. *by H***R on 1 October 2019* I've bought several of these for use in our family's folding bikes.

Top service and good product. ### ⭐⭐⭐⭐ Excellent tube Super Value *by D***E on 5 August 2016* This was delivered very quickly, much faster than expected. The tube was in its own box complete with dust cap. A well made strong tube that smelled very strongly of rubber. It was very easy to replace the old tube. Works exactly as it should Best of all, it cost only 30% of what it would have cost at my local bike shop delivered.
