Standard Presta Valve Tube

Always difficult to snugly fit the pump to the valve. Sometimes you pull the pump connector and it traps the presta valve and then the tube is void.

I recently purchased butyl 700cx20-28 48mm tubes from Specialized(Four or more purchase so far). I’ve noticed that the valves are slowly leaking air. I’ve removed the valve core and inspected the core gasket/seal, but the issue persists. However, I’ve found that tightening the valve core lock nut/top nut very snugly by hand after inflating to the desired pressure helps. Specialized should look into this matter. The butyl tubes purchase is worse that latex tubes because of this issue. Regards WJ

I've had issues with stems with assorted brands. These seem the most consistent for the price.

What I initially thought was a slow puncture occurred over three months in different wheels. These were the proprietary tubes which came with the bike. No puncture in either tube, tested underwater no obstructions in rims or tyres. It can only be an issue with the values, air let down as the valves and caps held no resistance. Reading another review people seem to be having similar issues with the same inner tubes

I bought two 700 x 32-50c 60mm tubes. No matter how much I pumped air intothe valves the they would not seal. Air kept leaking form the valves.03015-0316

It shipped fast, and it’s a tube not much more to say.

Buen producto y calidad

I have cycled since I childhood, I'm 71 now, I do my own maintenance and still prefer the simplicity of tubes. These are some of the best made tubes I've ever used, hands down.

This has been my favorite tube for many years. These tubes are reliable and durable. Not much more you can ask for in a tube.

It’s a tube. It holds air and works.

As has been mentioned here by others, I too had issues with the two I bought. The valve on both of them came out when the pump was removed. Needless to say, I will never buy another, and I strongly recommend you stay away from these.

Great quality

These are quality tubes at a great price and delivery and pick up at my local store was a breeze.

Excellent quality and performance!

A must for my fat gravel tires

I am a big big fan of Specialized bikes since born, i am getting every 2 years new bikes. best dealer and best products. cant imagine and explain how i am happy. THANKS TO THE COMPANY

Never have a problem with these tubes and the packaging allows for improved ease of carrying a spare while long distance cycling.

Awesome tubes. I’ve been using for years. I always use Specialized Flak Jacket tires so I can’t even imagine getting a flat!!

My main interest was on the weight side in comparison to latex tubes which are why more expensive. I got the 700 x 20.26c with 60mm Presta Valve @ 69gr

Great tubes 👍 easy and a breeze to install. Kinda heavy but it’s good for training or recreational rides

Adhesive failure where valve attaches to tube. I have good pictures of failure. New tires and tube installed at dealer. The tire was flat before 2nd ride. Removed tube and found defective condition. Also MADE IN CHINA stamped on tube along with Specialized brand. Recommend to NOT TRUST THIS PRODUCT until you pump up the tube outside the tire and check for separation.

Any time we can buy an OEM quality product for a competitive price, it's a win. I won't know how good it is until I have a flat, but needed a new spare tube size to match my new Specialized Bicycle. I am highly confident the product will meet expectations when needed.

The tubes are sturdy and last as well as other quality tubes.

I love using these tubes. They are durable and pretty reliable when used with liners. Make sure the stem valves aren't loose, but overall, great tubes for the price.

Quality products. Competitive prices. Fast shipping. Great selection.

Did not even last ~ 20 miles. On the 2nd day, the stem base gave up from the tube and is leaking air. The original tube that came with the bike, lasted 3 weeks (no thorns or pins or nails). The new tube lasted only 2 days. I have tripled checked the tires and have not found any offending material.

I like the fact that they span 20 thru 28 tires and I've totally switched from Continental tubes to Specialized tubes. Can't beat the quality & the price.

Great service too

Good quality.

Good tubes they don’t leak air way better than Schrader valve I will always buy Presta valve tubes

Bought three of these and all three had a malfunction issue where the valve separated from the tire when removing my bike pump after inflating. The valve just slid right out, releasing all the air. These were expensive tubes and to have this issue was incredibly frustrating, especially when it happened while replacing a tube on a ride. Need to be able to depend on tubes and I can't depend on these.

I have not used this tube yet as it is a backup. I have used these tubes previously and they are quality tubes.

Good price 👍

Just had my fat boy serviced and some repairs done the best it ever been well pleased cheers wil

A very good tube at a good price point. That is, good value.

Leak hardly any air, the best inner tubes I have ever used.

Great tubes for the price!

Shipped relatively quick!

Great long lasting tubes

My go to tube

Great quality! Keeps us confident! K&K

Needed new tubes. These are the trusted one I use. The presta valve actually fits my deep v frames.

Best tube and great price! Thank you!

Quality seems good, fair price.

specialized stuff is often the best products. The basic tunes for instance are not big and bulky and have a wider range (20-28) of width than other brands. So they can be used on either my gravel or road bike. Armadillos are also the best puncture proof tire on the market. They outlasted gatorskins in my head to head test where I put one on front other on back of both of my bikes. Got more flats on the gatorskins and the gatorskins wore through to the shielding underneath the rubber before the armadillos.

We use these tubes with Armadillo tires and never had any issues

Great tube. Good packaging, correct fit for flat tires as advertised.

Reliable tube. I only wish I could get a longer valve at this tube size.

I've used this tube for years. Very satisfied.

Great service thanks

I am not a fan of tubeless. Call me old school but no mess, no clogged valves, no worry about when stans is dried up. With the butcher T7 I run 19-20 pounds with tube and extremely rare to get a flat. I ride rugged New England trails with sharp stone.

Does what it says on thee are packet

Used these tubes for past several years and haven’t had any problem. Change tires and tubes every two years or sooner based on 5,000+ miles. Not buying any other brand.

Great tubes for the money

Good thing I purchased 6 of these because 1 had a leak at the stem. Otherwise these are good tubes for the price.

Good tubes, great price, fast delivery!!

Good tube. No problems.

Quick service.

Exelent package quality inner tube hard to punch recommending

As advertised.

Good tubes

it works as a standard presta tube. no issues.

Good tubes , use them on many of my bikes, so far reliable and no flats.

Good tube for the price

Good tube at a fair price

Bought as spares, I'm running the turbo tubes right now and so far so good.

Quick delivery

Good tubes and fast delivery

Good tubes, they hold up to everything I do with them in my bike. No flats or pinch flats.

It's as tubey as tubes get. Holds all the air.

Perfect tubes

So far so good. Very fast delivery.

Only use these tubes. Sure you can get tubes much cheaper but who wants to spend their ride time fixing flats. These work super well.

Great tubes…I’ve never had problems with these!

I installed new 29 inch 2.6 inner tubes. Driving as it should be 👌👌👌.

Solid construction and fit.

Very good tubes

Arrived quickly

good tube.

Does the job

Happy with the product

I always buy Specialized tubes. I think they’re the best ones available.
