Review: FULL OF HOLES - This is the worse inner tube I’ve ever bought, it had 6 pin prick holes In it! Tried to fix them just for sake of it in this lockdown gave me something to do! Absolute joke are these even genuine products or cheap knock offs!!! DO NOT WASTE YOUR MONEY I’ve had to give this a 1 star I would give it zero but it wouldn’t let me Review: Avoid - Bit hasty on the first review promoting these innertube, AVOID please, I install the innertube but didn't get round to using my bike, had 10 mins of use when riding then when flat slowly, I made sure before fitting there were no debris or nails or anything. Did the good old innertube in the water trick, HOLES SMALL CRACKS EVERY WHERE. Clearly poorly made. ## Features - Fits 275 inch wheels - 42mm Presta valve - Product Received packaging may slightly vary with catalog image and differs with respect to Size and Dimensions - Sport type: Cycling ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00G8QH7UG | | Best Sellers Rank | 2,405 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) 22 in Cycling Tubes | | Bike Type | Mountain Bike | | Brand | Continental | | Brand Name | Continental | | Compatible Tire Width Maximum | 63 Millimetres | | Compatible Tire Width Minimum | 17 Millimetres | | Country Of Origin | Germany | | Customer Reviews | 4.5 out of 5 stars 3,490 Reviews | | EU Spare Part Availability Duration | 2 Years | | Global Trade Identification Number | 04019238619591 | | Included Components | no | | Item Diameter | 27.5 Inches | | Item Type Name | Continental MTB Presta Valve Inner Tube - Black, 27.5 x 1.75 - 2.5-Inch/42 mm | | Item Weight | 0.23 Kilograms | | Item Width | 1.75 Inches | | Item diameter | 27.5 Inches | | Item width | 1.75 Inches | | Manufacturer | Continental | | Manufacturer Part Number | TUC82311 | | Manufacturer Warranty Description | producer | | Material | Rubber | | Material Type | Rubber | | Model Number | 182311 | | Size | 27.5 x 1.75 - 2.5-Inch/42 mm | | Unit Count | 1.0 count | | Valve Length | 42 Centimetres | | Valve Type | Presta | | Valve type | Presta | | Wheel Size | 698.5 Millimetres | | Wheel size | 698.5 Millimetres | ## Product Details - **Brand:** Continental - **Item diameter:** 27.5 Inches - **Material:** Rubber - **Valve type:** Presta - **Wheel size:** 698.5 Millimetres ## Images ![Unisex's 42mm MTB Presta Valve Inner TubeBlack, 27.5 x 1.75 2.5Inch/42 mm - Image 1](https://m.media-amazon.com/images/I/61AMAAKwQ8L.jpg) ## Questions & Answers **Q: Can I have my money back?** A: You’re asking me can you have your money back?
