Hello,

Can someone please tell me if I can use these valves to replace tubular removable valves ?

I am looking a place (Europe) to buy a lot of them because they break easily and I can't find them in local stores.

Thanks

What's breaking ? I've never broken a valve in 30 years of riding....

I pump the tires almost every day and after sometime the valve bends and breaks. It doesn't happen often but it happens. Please check the red circle in the photo to see where it breaks.

You need to be more careful when pumping. What type of pump are you using ?
There shouldn't be any sideways pressure on the valve stem.

It's a pro floor pump (https://www.pro-bikegear.com)

Maybe I should get another high quality floor pump ? Please if you can suggest a floor pump that I can buy from Europe (like wiggle, chainreaction) . Thanks

First off, not all presta valve cores are removable, the one you pictured seems to be the non removable type, so you can't replace it. The issue you are having probably has less to do with your pump than it does with the way you are using it. If the valve is bending, you are not attaching and removing the pump properly, you need to change what you are doing.

To answer the OPs question: In my experience most sew-ups do have removeable cores as do various tubes for clinchers. I can only judge by sight but the ones you linked to should be right. I've used Tufo valve cores in the past. Here's a link to one source. I'm sure there are others.

No, you're doing it wrong. Floor pumps with a hose are the least likely to cause problems. Hand pumps sometimes cause problems due to poor technique.
The pump head should go straight on & off. Don't twist or flex it sideways.

Certainly not all though. Conti Giro's are one tubular that comes to mind that don't have removable cores.

Thanks for the replies. The photo I attached was just to show where the valve breaks. I am using tufo and continental tubular tires that you can remove the valve. The conclusion is that I am doing something wrong. I just attach the hose and start pumping. One thing that might be the problem is the weight of the hose. I attach it in a way that I don't bend the valve. But when I pump, I am using both hands to add 150 psi. Maybe the weight of the hose and the air passing through causes the problem?

The hose is suitable for both presta and schrader valves.
