ContinentalUnisex's 42mm MTB Presta Valve Inner TubeBlack, 27.5 x 1.75 2.5Inch/42 mm

Very sturdy, thick material. Works well, needed this stem to fit the rim and it works like a charm. Good quality for a decent price.

Well made will buy again

Works as it should.

I didn’t know I was buying a tube with a Presta valve. Luckily my new cordless pump has a Presta adapter. But I couldn’t use the pressure indicating cap that fits only on standard Schrader valve.

I’ve been a cyclist for years, and I’ve had my share of flat tires. I was a professional at the "Walk of Shame." But then I bought the Continental 42mm MTB Presta tube.This isn't just an inner tube; it's a superhero. It has conquered thorns, glass, and countless angry-looking rocks without so much as a whisper of a puncture. It holds air like a politician holds a promise, only this one is for real. I now ride with a newfound confidence, a tiny piece of rubber having restored my faith in the world.This tube has brought me more peace of mind than a well-tuned suspension. I am no longer a cyclist; I am a conqueror of trails. Five stars. Don't buy any other tube.

Super easy to install, there's a mounting ring that let's you attach the valve to the tire which is SO much easier.Ride is nice tho, can't complain.

Made from good material

Seem slightly oversized for my 27.5 wheel but otherwise they are great.
