Bought the 2018 Giant Contend SL 2 Disc about three weeks ago. I'd been riding a 2017 Tomasso Tiempo, which I love, for over a year now but decided I wanted to 'upgrade' slightly since I was starting to get a little serious about my cycling. I searched a long time before I settled on the Giant Contend. I ordered it from another local bike shop as mine didn't have the bike in the color I wanted. When the bike came in I wasn't disappointed. It's a beautiful bike and I couldn't wait to ride it. Unfortunately, I work shift work and so I didn't get a chance to really 'test' ride it until the day of a bike event I'd been preparing for several weeks in advance. The bike rode like a dream! That is, until 4 miles into the race, I realized that I was starting to really 'feel' the cracks in the road from my rear tire. When I got off my bike and checked the rear, I found 'white' crap had been slung all over my saddle bag and the rear of the bike. I didn't know what it was until I got off the course and removed the tire off the rim and saw the rest of the sealant inside 'STILL' not doing what it was designed to do...seal off a puncture. Now when the puncture happened mind you, I was right on the heels of 1st place and feeling pretty good about the pace so far! The tire looked to be actually 'cut' by some gravel that 100+ cyclists rode over. My bike was the only Giant there and out of all those different bike brands on scene who also had to ride over that same very short stretch of gravel, I was the ONLY one who got a flat that day!! Luckily, a LBS owner who sponsored the event that day, was also riding in support of the ride and came by with a tube and expertise to help me get back on the road. Needless to say, "These tires gotta go!!!" I've ridden my Tomasso Tiempo for over a year, through all kinds of road crap and through road debris after hurricane Harvey and I have yet to have ONE flat on it. I have my first flat on a brand new, more expensive, and supposedly better designed Giant. Don't get me wrong, I love the bike. Love it!! But the tires...I'll be nice and say, "I ain't a fan. Not AT ALL!!"
Purchased a Giant 7 for touring. Threw the tyres away after one puncture, couldn't fixt it, sealant did not work, returned to Schwalbe marathon tyres with inner tube for long distance touring.
I have a crosscity..great except tyres it came with. run flat..but punctured easily. Just seemed to spit sealant everywhere and go down. I just replaced with marathon plus tubed. job done. also bought giant roadbike. I got the impression the run flats where stronger.. tread top..good but walls weak and 1 month..a tear. have replaced with maxxis rf kevlar..altho front original still running. see what happens...
I'm late to reply but I've been riding this every day to work and for fun for 4 years. It is much less hassle than tube as you don't have to stop or fix most punctures as they seal themselves. I've had a couple flats while riding on punctures that were odd shaped and wouldn't seal. I carry a tubeless kit (its like thick gooey string that you run through the puncture with a pick). This takes 10 seconds and will usually allow the sealant to do its job. You pump it back up (I use co2) and ride home. On some punctures that just look weak, once I'm home I'll fix them from the inside. I clean the tire, add rubber cement, dry and put a patch from the inside of the tire. I haven't had one go bad yet.
I bought a Bike, after less then 10km this "best tubeless system available" let me down. Why again did all these bike builders think they had to reinvent the wheel...
but what happens if you had a puncture or leak during your ride? how long will it take to repair and what special tools you need to bring when riding? unlike a conventional tire you just need an extra inner tubes and some patches about 10 mins or less your riding back again...
A friend of mine had a flat on his brand new Giant with tubeless on his second ride, and required putting in a spare tube - it took around 15'ish minutes as the valve stem wasn't coming out very easily and none of us were familiar with the setup at the time. As we learned, a good idea is also to put in a pair of latex gloves (like the Park Tool ones) in your seat bag as the sealant is pretty sticky on your hands.
My friend picked up a thorn on his first ride, we rode 15 miles home I the pulled out the thorn and a speck of sealant was all that showed that he had a puncture.
I'm about to get a giant bike with tube ready tyres. 6 summers on a halfords carrera special and never had a flat. This routine seems like a load of hassle and deffo can't be done at the roadside. Does the giant tubeless tyres come with inner tubes in?
Hello Giant, in this video you recommend 30ml of sealant for tyres < 28c. I just purchased your TCR adv pro 1 that comes with said wheelset and tubeless tyres. Will it impact negatively on the tyre or the wheelset if I were to put 60ml of Giant's sealant into the valve core? Thanks for replying
I use a normal track pump and see no reason to see why not, I think having an accurate gauge is the most important as I suspect too high a pressure could be an issue with no tube.
Mububban23 says: "Can these tubeless tyres be inflated with a normal floor pump, or do you need one of those high volume tanks for rapid inflation?" == The way I understand it, large volume air supply is needed only once after the installation until the beads seat on the rim. To top off the pressure regularly, you can use the regular floor pump or even portable mini pump if you don't mind many pumpings.
I don't recommend gavia tubelees, in 6 moths I have 8 punchers and now I need to replace new tyre. A expert mechanical tell me that many giants bikes have the same problem because gavia tubelees is not strong enough. Bye Gavia for ever .
Gotta love this new hookless/tubeless BS. Manufacturer marketing BS'er says it's better for the environment. But now: rim tape, sealant, tire lube(?!), alcohol-based cleaner, impossible road-side repairs. This is just engineers doing engineer stuff to justify their continued existence. I'll take clinchers and tubes, and mechanical groups for that matter, thank you very much.
Will 70% isopropyl alcohol works as well? I need a tubeless tire specific pump? Anyone using a normal floor pump to set up or replace a tubeless tires?
You can use a normal floor pump for most things except the initial seating of the bead. For this you need a pretty good flow of air that will still push the tire against the rim even though it's leaking from everywhere. You don't need a compressor though, if you don't have a special pump, just use co2 cartridges. It's a couple bucks to seat a tire and then you're done.
@@NeutralGenericUser It translates roughly to "exceptions do confirm the rule" and yours is an exception. The rule is that bikes even nowadays still do come with tubes. Tubeless bikes from the shelves are the exceptions.
@@ralfrufus6573 and you determined that my bike is an exception based on? New technology trickles down from the top. Most (all?) the high end Giant models come with tubeless from the factory. It'll take a while before the low-mid range have the same luxury, just like it'll take a while for them to get more than 8 speed drivetrains.
Whenever so many proprietary tools are needed, be assured it's NOT worth it. I mean, what a pain in the arse! Just give me a REGULR tire that I can use and repair with REGULAR tools. This is garbage.
You forgot to mention the GIANT air used
Do I also need GIANT 50% Isopropyl alcohol solution?
You can also buy GIANT tubeless air

What’s the procedure with flat tire while riding ? What are you supposed to carry with you? I am a clincher Rider for the last 15 years

I think Mavic can make a 1 min video for their system:D

Is giant tcr adv 1 tire is prefilled with tire sealant?
Where do I buy Giant premium air?
So better drive with tube tires.
Because this is too much trouble
and what would be the advantage with tubeless tires??
How do I find out what size tape to use for my wheels? Is there a chart somewhere. I have 2017 Defy 2 with PR-2 wheels.
You look up inside rim diameter and pick the tape that's 1-2mm larger
The audio of this video is making me mad.
can I anyway use tubes with this tubeless system? or does it ruin it?
Are y dumb ?
hi, i have sr2 wheels , can these wheels be tubeless ?
thank you for this video
but what happens if you had a puncture or leak during your ride? how long will it take to repair and what special tools you need to bring when riding? unlike a conventional tire you just need an extra inner tubes and some patches about 10 mins or less your riding back again...

They don't need tubes and you don't need to do it at the roadside
Where in europe can I order the washers for my Giant XCR-0 Carbon Wheels?
What size are the valves for these tires?
giant size!

No, it better to put more
where do i get that tool at 3:08?

Can these tubeless tyres be inflated with a normal floor pump, or do you need one of those high volume tanks for rapid inflation?

Wash your hands with giant water
Literally impossible to install. These Giant tires are way too tight.

TX. But it seems like a lot more hassle compared to riding with tubes.
See my reply below I've been riding this exclusively for 4 years for work everyday and fun. Much easier than tubes.
@@theonlyguills bollocks
i use Levers. it dosent do anything to the rim? lol its made for this? OuO' i have 60mm rims.
try getting one of the rim way to tight.

Maybe i also need a giant Richard
Get your mind out of the gutter boys
Get silicone glue the tyre to rim, it's the only way to get it to stay on, stop making in-house and get a decent manufacture

Giant best bikes but their tubeless tyres are shit. Didn't last a month had sealant spilling everywhere.
This is insane. Mavic has much easier system.
やっぱし空気入れの問題が難ですね
This looks complicated I quit
Yeah, I'd rather pay my LBS to do the work. No way I'd trust my skills for this.
Dear Giant, why don't you sell your bikes already tubeless from the shelves? Why do you expect us to do the job afterwards?
My 2021 Fastroad Advanced 1 came tubeless from Giant, so... :/

this is rubbish 4 giant rims and tyres none but none will stay seated doing my head in garbage , my MTB Reynolds rims pop straight on Giant is crap
Step one - buy ANY wheels other than Giant wheels. Junk.
What a shit system
No thanks
