punctures

jag con

Hi all i only have the road bike since friday and have had three punctures already the first two were on the original tires so i fitted a set of Schwalbe Blizzards puncture resistant tires which i bought to fit on the bike and keep the others as spare, and after only 2 kms i have had another puncture.

I dont know is this just bad luck or maybe the tube tape is not good enough. Its annoying as im trying to lose weight and get fit and healthy.

Im meeting Mr Skevington tomorrow evening for some help on servicing so will have a look at the rims.

So my real question is am i unlucky or is this a regular accurance.

You're unlucky but it might be something to do with what you're doing.
Are your tyre pressures high enough (~100psi)
Are you correctly installing the tubes? Did you replace or repair the tube? Did you check the tyre to see what's causing your punctures (e.g. embedded glass or nail or something?)

Lumen

What tyre pressures are you running? What size are your tyres?

Hi guys the tyre pressure are 100psi the tires are 700 by 23 i will have to check the tires later for glass or objects
The pressure i pumped into them on Monday was 100 psi and went out this morning but did pump the tires up they seemed fine do they lose much pressure in two days.

Check the rim tape carefully would be my advice!

You can just be unlucky as well. I had one week (Mon to Fri) where I think I suffered 5 punctures. All in different parts of the journey (although one was a pinch flat from hitting a pothole after having repaired a puncture that morning).

I got a puncture last week but that was my first in what I reckon must be a couple of months. It's easier to spot glass when the roads are dry.

Just check your tyres regularly for embedded glass and crap also keep your tyres up to correct pressure.

By 'tube tape' I presume you mean rim tape between tube and rim?

If however you man the tube protector tape you can buy and insert take it out NOW! The stuff caused me no end of problems before I twigged and took it out. So ironic that something that is supposed to protect against punctures actually caused them:rolleyes:.

Anyway, just in case you have this inserted...

Are the punctures on the valve side or on the opposite side?

Hi Kona the wheels are Bontrager ssr i dont know yet where the puncture is coming from i have to have a look at it later. What info can you tell from your question.

well is the puncture in the same place all the time? If so you can then locate the offending item either in the wheel or the tyre.

Valve side = Your spokes are causing it. Rim tape may need to be adjusted/replaced.

Tyre side= you have something in your tyre causing the issue, It may be lodged in tyre still so try find it(be careful they are usually sharp)

The sides = Your rim may have a rough edge, usually where the rim is welded, bit of coarse sandpaper will do the job.
Or, your tyre could have pinched the tube on the way in, put a bit of air into the tube before you refit everything, helps things fir in better with no pinching.

If you used a patch, the patch could be ****(they usually are).

Patches are usually good - if you apply them correctly. I've patched tubes that have lasted years after being patched. If a tube is properly patched it is the same as a new tube and is no more likely to be punctured than a brand new tube is.

Most people don't let the glue dry or some other impatient mistake and therefore the patch doesn't hold.

Can be *really* easy to miss these. I had glass in the tyre under the kevlar belt last week. Took a few minutes to find it by feeling for lumps, and then even longer to get it out due to the way it had worked its way in.

Is it just me or are they waaaaaay more common on the back tyre??

This is true in my experience with traditional patches, they are as good as a new tube- however pre-glued ones are only a temporary fix.

It's not just you, they are way more common on the back.

Good thing they are too, puncturing the front badly (blow-out) at speed is not fun.

Patches are ****ing ****, those instant ones are even worse.
I patch old tubes from people who dont want them, glue allowed to go tacky, patch on, clamped down with a pliers for 2 hours, left lying around for months even years and then ,even then some burst.

Save yourself the mess, grief, time and just put a new tube in. I can only pity the poor eejit at the side of the road in the pissing rain trying to patch a tube.

And even then your not guaranteed.
