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

### ⭐⭐⭐⭐ 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!
