Review: Solid tube with clean valve fit—holds pressure, no puncture drama, and fits wide MTB tyres spot on. - Used this on a 27.5" hardtail with 2.25 tyres—fitted clean, no pinching, and the valve seated tight. Presta valve’s 42mm length is ideal for deeper rims, and it didn’t wobble or leak. I’ve run it across rough trails, gravel, and wet commutes—no flats, no weird bulges, just solid pressure retention. Tube feels tough but flexible—easy to install without fighting it. I always dust with talc before fitting and this one slid in smooth. After a few weeks of mixed riding, still holding air like day one. It’s proper stash-worthy—whether you’re swapping out a flat or building up a fresh wheelset. I keep a spare in the van and one in the kit bag. 👍 Pros ✅ Fits 27.5" tyres from 1.75 to 2.5 wide ✅ 42mm Presta valve—ideal for deeper rims ✅ Holds pressure well—no slow leaks ✅ Easy to fit—flexible but durable ✅ Trusted brand—Continental quality 👎 Cons ❌ No valve cap included ❌ Not tubeless—standard tube setup ❌ Slightly heavier than ultralight tubes ❌ Needs careful install to avoid pinch flats 🧭 Personal Review If you want a reliable inner tube that fits wide MTB tyres and holds up under pressure, this Continental earns its spot. I’ve used it across trail rides and daily commutes—no drama, just clean performance and peace of mind. Proper stash-ready gear for anyone who wants their ride sorted without the faff. Review: A good value, solid inner tube - I don't like everything Continental makes, but these inner tubes seem like a solid, good value proposition. I put them on my Scott Genius MTB with Maxxis tyres and so far I can't really fault them. I do mostly trail and hill riding so there's a mixture of road surfaces, and the Continental / Maxxis combination feels good. You might be able to get better tubes, but these look like the right mix of quality and cost ## 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 | 5,227 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) 48 in Cycling Tubes | | Bike Type | Mountain Bike | | Brand Name | Continental | | Compatible Tire Width Maximum | 63 Millimetres | | Compatible Tire Width Minimum | 17 Millimetres | | Country Of Origin | Germany | | Customer Reviews | 4.5 4.5 out of 5 stars (3,474) | | 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 | | Manufacturer | Continental | | Manufacturer Part Number | TUC82311 | | Manufacturer Warranty Description | producer | | 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 | | 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/81CZ-Syr0IL.jpg) ## Available Options This product comes in different **Pattern, Size** options. ## Questions & Answers **Q: Can I have my money back?** A: You’re asking me can you have your money back?

I put them on my Scott Genius MTB with Maxxis tyres and so far I can't really fault them. I do mostly trail and hill riding so there's a mixture of road surfaces, and the Continental / Maxxis combination feels good. You might be able to get better tubes, but these look like the right mix of quality and cost ### ⭐⭐⭐⭐ Good quality and value replacement inner tube *by M***1 on 20 March 2021* Purchased this to replace a spare I keep in the garage which has been called in to action following another puncture on my son's mountain bike. I have repaired inner tubes previously with varied success and often it's just easier (and at these prices) good value just to replace the inner tube. As you would expect from a brand like continental it's good quality and well made. My only observation when fitting it was that around the valve is quite firm and I had to use the tyre irons to manipulate the tyre back on to the rim as the firmness of the inner tube at that point (deflated) made space quite tight. Not a problem once I had clipped everything back in place. Overall pleased and will buy again as I am sure I will need to! ## Frequently Bought Together - Continental Unisex's 42mm MTB Presta Valve Inner TubeBlack, 27.5 x 1.75 2.5Inch/42 mm - Continental 29" Bicycle Tube, 1.75"/2.5" 42mm Presta Valve, Black - Pedro's Tire Lever --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/48242524-unisexs-42mm-mtb-presta-valve-inner-tubeblack-27-5-x](https://www.desertcart.us/products/48242524-unisexs-42mm-mtb-presta-valve-inner-tubeblack-27-5-x) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-19*
