Bike got punctured need advise

[mrina...@gmail.com]

Hi Guys

Today when i started on my bike for my home i saw it was punctured. I blowed the tyre but the air didnt stay. The motorbike repairing people simply refused to repair it. As a result i had to tow my cycle 8km from itpl to marathalli.

I need suggestion on what to do next time if the situation repeats.

Kindly help

Carry a puncture kit :) ?

Most punctures can be avoided by maintaining the right pressure.

Hi john even i will come along with mrinal sometime to chkout how to fix a flat!

[Banibrata Dutta]

search Youtube for puncture repair DIY instructions. I did mine, for the first time, not too long ago, based on one of such videos. They other important videos are adjustment/cleaning of brakes (V-breaks, in my case), removing front and rear wheels (rear one being a bit more tricky, for the 1st time). Anyhow, you need a puncture repair kit and a small portable pump to make use of the kit.

I didnt know that fixing flats requires such study! I got my first flat some 30 km from home, on NH-7. Learnt on the spot and it took an hr. I now fix flats in a couple of minutes.

@hebbalites: come to iisc sometime tomo! I can teach you about fixing a flat

ITPL Backgate road has a couple of cycle repair shops (Opp. Bakery). If you forget to carry a puncture kit, that's the place you need to head to during the day time.

might want to consider keeping a spare tube with you.  (and a handpump, ofcourse, but handpump you will need anyway, even if you plan to carry a puncture kit instead of a spare tube.)  that way, you can replace the tube, and worry about fixing the puncture later.

btw, spare tube or puncture kit, remember to examine the inside surface of the tyre before putting the tube back in.  if whatever caused the puncture is still lodged in the tyre, you need to make sure you remove that first.  i carry a (small) nose plier because if something 'fine' is lodged in the tyre, pulling it out with fingers might be tough.

and last but not the least -- see the recent thread on tyre liners.  those can help reduce/avoid punctures in the first place.

+1 to that.

I always do some forensic analysis of the flat. I've had too many cases where the culprit was a large gaping cut in the tyre, or some debris(small shard of glass/tiny thorn still stuck in the tyre. which would cause trouble again and again.

[puneeth rao]

@ hari : Congrats tat u learnt fixing flats on ur own!! ur a real genius!

[Hari Krishna]

Fixin flats should be really easy. Anything better than my Fomas rims will almost always allow you to remove the tires without levers. Just replace and tube and carry on! At your leisure, you can do forensic analyses and patch the tube. 

I almost always carry just a spare tube and never a patch kit! All my patchwork is done at home, carefully!

I tried pucture kit and was really happy that I could do it right for the first time itself :-)
I always carry pump as most of the bicycle repair shop will not have it and Mobike repair shops won't fix it for you.

Cool...hw do you convert ur regular tyres to tubless?

Of course, you could go extreme like I do and go tubeless. Check out stanz tubeless conversions. However as an outsider (for now) i dont really know whether its economically viable in India.
I use tubeless on both my mtb and road bikes and never get an'instant' flat. The tyre will at worst hold air till I get home.

Not sure whether this will work, but I will post this in the group rather than via email:

Hmm,

It really depends on how serious you want to get. Probably one of the cheapest way to do it is as per this site:

http://www.notubes.com/Road-Tubeless-C78.aspx

However, road bikes are a lot more expensive to set up for Tubeless than Mountain Bikes. Roadbikes need tyres specifically designed for tubeless. THe tyre sets listed on the page referenced above are probably not the cheapest option you could go for, however, transferring the costs to India it does look expensive.

THere are varying reports of success with Tubeless, and a search of many forums shows both pros and cons, as seen here:

http://forums.competitor.com/topic/3979

I have run tubeless on my Mountain bike for quite a while and love it, I don't ride the road bike that much, but the tyre has stayed up. I can't vouch for it under Indian conditions obviously.

[rooosterboy]

Pradeep,

If your question is about Mountain BIke tyres, it is a lot easier than road bikes, see my response previous.

Mountain bike tyres manage tubeless conversion a lot cheaper, as you can typically use standard MTB tyres with either special rim tape, or by doing what people call 'ghetto tubeless' (look it up on Google)

I mentioned in a separate email that I will be in Bangalore for a couple of years starting in around late October, I will be bringing my bike kits over and would be happy to run 'tubeless workshops' for Mountain bike riders if anyones keen?

[rooosterboy]

Johnny,

If only punctures could be avoided by maintaining pressure, however, you are partly right. A lot of punctures are caused by pinching the tube beneath the bead of the tyre when pressure is low, as your corner or hit a bump it can cause the inner tube to squeeze out under the bead and 'pop'.

However, more common is the punctures caused by shards of glass or metal slowly digging into the tyre and creating the elusive 'slow leak'. Someone else had advice that if changing your own tubes, run your fingers gently on the inside of the tyre to try and spot the culprit. 

Puncture kits would definitely be the easiest option to keep going as long as you know what you are doing (and you have a pump as well). I would also advise, if you spot that you have run over some glass, stop and check the tyre to see if any small shards are stuck in the rubber, often getting the shard out early saves it digging in and causing the puncture later.

[Prashant Sharma]

Thanks for the workshop offer, Bruce ! 

I would be keen to see that. And I am sure few other as well would join. We look forward to see you in Bangalore soon.

Regards,

Prashant.

I use regular tubes on both MTB and roadbike - not too many flats off late, so no major pressures to change - however am curious, so do announce any workshop you hold here, I am sure you will get a lot of folks who'd like to come and take a look.

Finally i got my bike repaired today.
Replaced the tube which was totally cut and even bought a spare tube.
Thanks all for ur help.

[Shankar Shastry]

While this thread was going on, I found 8 flats on my front tyre and replaced 3 tubes - all on the mountain bike. I wonder how I rode back home with so many flats on the previous trail ride. Now I have a dozen spare tubes to be patched up!

[pradeep naidu]

Shankar, is it true if you put a tireliner the avg speed drops.. I have for my front tyre but the avg has not dropped but improved to. 5.

[Shankar Shastry]

Sometimes you go faster because you're much more comfortable. I don't know whether tire liners affect average speed but the reason I don't have them on my bike is that they add more weight and I'm a bit of a weight weenie when it comes to my mountain bike.

[Vasu]

Hi,

A "weight weenie emptybeer" - now that is a classic Oxymoron!!

No, avg speeds do not fall if you put tyre liners. Avg speeds fall when you are not on the drops and catch the wind like the sail of a ship.
