Permutube are not good to ride on Middle ground is a heavier puncture resistant tire if you are running racing tires Spare tubeS, tire patch, tube patches, and a pump. Tubeless has a lower risk of failure but field repair is harder (you can put a tube in a tubeless).

The presta valve has a tube, a threaded pin and a lock nut. Your pin won't move down and you hit it with the pump - and rightly so! Try lubricating the pin with WD40 - ensure the locknut (silver in your pic) is unscrewed all the way (lefty - loosey, righty - tighty!) The WD40 may dissolve any 'gunk' that is stopping the pin from moving down under air (or ...

Straighten it. All you have to do is let the air out, push the valve in straight and then re-inflate it. You may damage the tube near the base of the valve if you leave it as is when the tire takes a hit.

It should be straight out, perpendicular to the rim. Otherwise you risk damaging the tube. When the valve stem is at an angle the valve isn't free in the hole – it is trapped by the edges of the hole where they bind the stem. The edges of the hole may cut the stem which will be moving a little bit as the tire and tube flex over bumps and the like. There ...

Your solutions have all pretty much been said, it seems to be a problem with the rim. However, instead of just checking the rim tape, check the whole inner rim to make sure there are no metal shards or other pokey things embedded in the bottom or inner walls. This happens a lot with v-brakes especially, so be aware. Speaking of brakes, I also wanted to ...

Schwalbe tubes are both Seamless (they're extruded rather than vulcanized pieces) and have a higher butyl content. The are made in their own facility, and they don't make tubes for anyone else. They've been independently tested to hold air better than anything on the market. So no, not all tubes are the same, they`re not made all in the same facility!

I would say, you just didn't put the tire on well. When you inflate the tire to half its recommended pressure you should check that the tire seats well for the whole diameter around the rim on both sides. If it came out even a little, push it back in (may require some deflating). Otherwise the pressure may push the tire out like you had, and then the tube ...

I agree with your diagnosis: it must be related to the rim tape. Take it off and inspect it and the rim below. If you don't find anything obvious, buy new, good quality rim tapes, check there are no sharp edges, and reinstall.

Tubes expand quite a lot as they are inflated - Try pumping one up on its own and see how quickly if expands (don't over do it unless you never want to use the tube again.). The way tubes and tires work, the tube holds the air in, the tire prevents the tube expanding. The 1.5-2.2 means the tube is suitable for a tire 1.5 up to 2.2 and is ideal for you 2.1 ...

Okay, im sitting stranded outside a 711, just popped my FRONT tube this time. But, i think i finally figured out my issue!! So I've been getting a ton of flats, all mainly in the back tire, since i started riding Almost a year ago. For that year ive been goin to the same bike shop, and buying the same CST tubes. Again, they say they can take 65 psi, but ...

Wow this is the flat tire question that just keeps on rolling In review: Installed a cheap 26 X 1.25 Problems from day one Patched tire with tire and even more problems exactly where the tire patch was Installed another cheap 26 X 1.25 and put in preemptive complete tire patch using the last 1.25 and nothing but problems Stop using: Cheap ...

Currently I weight around 300 lbs, ride bicycle daily 10-20km, and did not have flat for months. Yes you need decent tires, and you have to inflate them properly. Search the web for the puncture resistant tires, and choose one that has best reputation. They cost much more than bargain tires, but when you factor in how much it cost to change inner tubes ...

They say they take 65 psi, but I've had them pop at 55-60, so I keep them at 45psi, 50 if I can get away with it, and sometimes 35-40 if I'm using my little hand pump Well, there's your problem. 40 PSI is just not enough pressure for a 1.25" tire, especially if it's carrying a lot of weight. You're probably getting pinch flats from hitting potholes and ...

I'm not sure weight is the main issue. There are several questions on this site from people weighing more than you, and the general advice seems to be that it should be fine. Sure, more weight puts bike under more stress, but bikes are generally fairly sturdy. But make sure that there are no missing spokes, and check regularly if there are cracks in the rim ...

Firstly, you are one impressively persistent woman! Yes, of course weight is a factor. You just need equipment that will deal with it. In addition to the points made by jqning, I'm thinking that several things can help you Larger and better tires would help. I checked out the Electra website, but couldn't be sure which bike you have. Some do have bigger ...

@andy256 First let me say, this is my first time using this site so im still trying to figure things out, lol....still not sure if I am using this correctly. But thanks for editing my comment. Its a lot harder to make sure you capitalize every "I" and add the correct punctuaction and whatnot on a phone. 😊 @jqning Thank you for your answer! However i am ...

I typed this whole answer and then decided to cut to the chase, which I doing here. IF you do not have a tiny splinter hidden in the tire I think you are pinching the tube between the tire and the rim during installation. This explains the flats at 50-60 lbs. Losing weight is not the problem. It might be part of the problem - that is to say that someone who ...

Solved the issue of leaking air on the core part of the Presta valve by using Teflon tape to tighten the seal. Like this:
