Subject: Question on proper valve extension length.
Here's the story - I have 88 mm tubular rims on order along with Conti tubulars. The tires come with a 30mm valve stem with a removable core. When I comes to extenders, I prefer the removable core type versus the ones that mount over an open valve. I'm always afraid that the inside valve could close up. That wouldn't be a big deal if they weren't tubulars that would be a giant PIA to remove and reglue.

So, to the question, I have found 70mm extenders for use with removable core tubes/tires. That would add up to 100mm. Is that enough clearance to work with in terms of filling with air. I could also put on 2x40mm extenders but that might be overkill in length and add one more thread where air could conceivably escape.

Thanks in advance for any tips!

Initially most patients with mitral valve regurgitation have normal heart function. But when the heart starts to function poorly, patients will start to become more short of breath with exertion.
