this is more REPLACE a Tyre instead of FIX it. it’s always much more costly
to buy a new tube than putting a tip on where you neeed, yes , it’s only
for temporary using, but it works well. can you guys actually upload a
video of “how to patch holes on tube?” plz
Getting a flat tire happens to all of us now and again. In this video
Daniel Lloyd shows you how to fix it and get back on the road.
Cheers lads, simple tutorial but useful for a beginner like myself!
What’s your opinion on using sealant in your tubes? I’ve never had a flat
with that set-up. knock knock…
GCN videos, always interesting, informative, and usually funny! Thank you
guys. I always look forward to your next video.
I have ridden for years, and on different surfaces. I have never had a flat
tyre. Knock knock.
No valve nut?
Thanks for the video, it helped a lot!!!(:
Can you guys do a video on changing handlebar grip and putting the caps
back on! That would be fantastic!
What pump are you using? it is really small… can You get high pressure?
If a piece of glass slices the tire sidewall, enough that a small hole
remains that the tube is visible through, do you replace the tire
completely or attempt to repair (is that possible?)
would you recommend clinchers instead of tubulars if I don’t race often?
Ran over a bloody pothole while I was looking back at my friend. Blew out
my inner tubes and I had to walk all the way back home. Luckily it was just
10 km.
Is there a place to get those water bottles? I’ve seen a couple videos and
it seemed like you all have hundreds of them.
I like this, will deffo watch a few times in future to make sure I would
know when out and about…
Shoddy video… Only about half the time will the offending object be found
in the tire. Remove the tire fully from the rim. Only then can you
carefully examine the tire visually as well as digitally(with your
fingers). After you put 15-20 lbs of pressure check the tire seating
carefully. As someone else noted pushing the valve stem into the rim and
making sure the tire is seated at the valve is critical. Push down any high
spots and work up the low spots till it is uniform. Then pump it up. After
putting the wheel back on and flipping the brake qr back on(it also may be
on the lever) then check the brakes…imake sure they are centered before
taking off. Doing this correctly (not the videos) adds 90 seconds to the
task.
They seem to have waited for one of them to actually get a flat before
putting out this tutorial, authentic ;)
Go sram!
had my first flat today. This helped a bunch! thanks
Your bike is a beauty!
don’t forget ot wash ur hands afterwards, so take soap and technical water
with you)))
Is ok to use tyre sealant?
Well done Mr Loyd, you can clip in on camera!
Are you selling outfits ?
I have an idea for video! I belong to the kind of people that almost
exclusively ride tubulars. I have many reasons: comfort, security, weight,
performance, its cool, I like the smell of glue, some tubular wheels are
cheaper, etc.. So, why don’t do a vid on puncture repair for the tub-folks?
(I don’t find them to be particularly cumbersome but nonetheless, I might
have missed some tips and tricks.)
Great vid dan. I watch all of your videos and while I’m well versed in
fixing flats I always get something out of gcn videos. On another not how
do you find the conti force/attack Tyres? Any good?
3:20 You should NEVER use a tyre lever to get the tyre back on the rim. It
is all to easy to simply pinch puncture the new inner tube with the lever.
I worked in a bike shop with Cytech qualified mechanics and they were
adamant about this.
The real solution:
If you are struggling to get the last section of tyre back on the rim, go
to the opposite side of the wheel and make sure that the bead is seated as
deep into the rim as it will go. The extra 1mm provided will give you the
freedom to push the remainder of the tyre on to the rim with your thumbs.
Thanks for the video. I would glad to watch if you make this video of
tubular tire version.
Normally only one Lever for magic! wheel thank god!
+タイヤを嵌めるときはバルブの反対側から始めるとレバーが要らない、と堂城さんの著書にありました。by自転車の教科書。
Just in case you get a flat…here’s how to fix it.
i would say another important step before pumping it all the way is to push
the nozzle into the tire so that the tube doesnt protrude when fully
inflated. i learned this the hard way…
A good tip is to look at the old tube to see where it has been punctured,
and then you can get a good idea where to look on the tyre in case of glass
etc.
Nice Cervelo. Is that your favorite brand? I bought an S2 this past
December, it’s definitely a Rocket.
Good timing. Just had a flat and my spare was torn up as well. Too long in
storage. Thanks for the tip
Great explanation! Very helpful.
That is a slow, and silly way to do it. Pump flat tire up, find deflating
hole, remove just that section of tube, patch, return into tire, and rim,
reinflate, ride it like you stole it ! Much faster manner of doing t hings
!
What about partially inflating the inner tube once it’s out to find the
puncture instead of searching for it by hand, that seems like the better
option… Also if you get a long gash you can use in my case a folded up
dollar bill to keep the inner tube from popping out of the tire while you
make your way home.
Porlock! Love it round there! :)
Nice and clear video! One addition though: I once learned a trick in my
bike repair shop.
Most, if not all, tires can be put back on the rim w/o the use of levers.
If you pinch the tire at the opposite side of the part that still has to be
put back on the rim, so it sits in the deepest part of the rim, you should
be able to get the remainder on the rim w/o using force and with your bare
hands.
Great vid from Dan. Question: how many spares is recommended to bring on a
ride? I presume at minimum 1 but have heard others say 2. Where would one
store the 2nd one?
Thanks for all of y’all videos, I never knew about the canter lever on the
breaks.
hi GCN im a fan of yours,i have a problem that what should i do if my
handlebar is loosen and i dont have my tool with me in the middle of
nowhere.Pls help me,its been troubling me for a long time.
I have had many flats over the years. The one pro tip I can give is: after
you take out the “flat” inner tube, be mindful of which way the tube was
installed and then try to inflate it so it has some decent pressure. You
might determine where the puncture was just by the hiss of escaping air. I
normally turn the tube around with it close to my lips to feel where the
air is coming out. Make sure you go all the way around the tube, and don’t
just assume you only have one puncture! I can’t stress this enough.
Once you know where the punctures are, you can compare the location in the
tube to the tire by where the valve stem is. Investigate those areas on the
tire completely and remove any debris, nails, glass, staples, wire, etc
that caused the flat. Carefully feel around the inside of the tire and look
for any other foreign material in there and remove it and don’t forget to
inspect the outside of the tire too. Then patch the tube if it’s only a
small puncture or replace the tube completely if it has more than 2 patches
or punctures.
The reason why I like to check the tube for punctures is I hate cutting my
finger open on sharp glass, or poke myself with wire or nails. Also, you
may miss a second puncture location when feeling around the tire if the
debris only lightly penetrated. As soon as you reinflate and ride off, the
pressure of your weight could cause the debris to poke through again
causing another flat. And I always recommend patching a tube first. Patch
kits are fast, cheap, and reliable enough these days. Keep your spare tube
only as a last resort, or where patching is impractical.
I hope this was useful, and drive safe everyone!
Daniel Lloyd makes a much better impression than that awefull texan who
once tried doing such a clip..
What pump are you using to pump the tire up, can you mention it.
Don’t turn the bike upside down because you might scratch the STIs, instead
rest your bike on the side. Because scratching the frame is much more
preferable!? This is bad advice!
