People either love tubeless or hate it . It's personal
Me I run tubeless on my newish TCR 9500 miles and no road side stops . Have had punctures but all have sealed . Yes more of a faff to set up change tyres etc
My other road bike the Defy I run with tubes roughly a puncture every 3500 miles so tubeless for me .
The key to getting tubeless to work properly is the tyre and rim interface which can be a bit hit and miss . My TCR came set up with giants own wheels and tyres which work so when I changed the tyre I stuck with giants own knowing it would work
An oft discussed subject. Here's a quick summary.
Some people use tubeless and think they are great.
Some people have never used tubeless, have no experience of them, and think they are the stupidest idea ever. Because.
Some people have used tubeless and didn't like them and returned to using tubes.
Give it a go. You have nothing to lose but your tubes.
It's not that simple. First you need your wheels to have rims that are tubeless compatible, then you need tyres that are tubeless compatible. If you don't have these, then you're in for a lot of expense. If you have both of these already, then you'll need a lot of patience to do the setup.
I have a pair of Hunt wheels which I bought c/w tyres already set up tubeless. They've been great and I have managed to replace the rear tyre myself when it wore out.
Last year I bought a pair of tubeless Mavic rims and had them built onto hubs where the rims had worn out. I then set these up tubeless myself with tubeless Continental 5000 tyres. One wheel was good after the first go, the other had to be re-done. There's a bit of a learning curve involved as well as care and patience to get everything just right. I even had to get the lbs to mount the tyres as they were incredibly tight on the tubeless rims - and this was after running them with tubes on normal rims for a couple of weeks.
I've not had a puncture on the tubeless tyres. Then again I've only had one puncture on my good bike with clinchers and latex tubes in the last two years.
I have never needed to stop and repair the tyre after setting up my wheels with tubeless.
It requires a bit more effort to set up, if done correctly will provide almost 100% protection against flint, glass, thorn punctures. Large cuts will deflate slower than a blowout, affording a degree of control when coming to a stop.
Tubeless is super comfy, when run at lower pressure- no chance of pinch flats.
Finally a half way setup is put Orange endurance sealant inside your inner tubes (75 millilitres) for 25 mm tyres. Thid will afford all the pinhole protection without the lower rolling resistance of tubeless
Word of advice, don't set them up in the house, or anywhere you don't want coating in a sticky mess. There are a number of stories where folk have cocked up the set up, and the tyre has popped off the rim, exploding sealant over everything. Also like someone who hadn't rebuilt his front suspension properly, and when fiddling with the forks walking through the house, the seal popped off spraying the house with oil.
Personally, I haven't bothered as my wheels aren't tubeless ready (although running tubeless ready tyres) and I'm yet to get enough 'issues' to bother with going tubeless.
