Why is Tubeless better.

[jcza]

 

Running at lower pressures MAY mean more grip BUT it also means you going slower.

 

 

 

Not true! Lower pressure on MTB is faster.

[TwiggzSA]

What's stopping someone from putting stans sealant into a tube? Then the only benefit of tubeless is that you can run lower pressure for better grip. Tubeless are heavier because of the thicker sidewall to keep the tyre structure under lower pressure.

 

Pro's: Better Grip, Comfort

Cons': Heavier

 

Is this correct?

[Jeepdude]

are we really having this discussion?

[jcmeyerSS]

 

You'd be singing a different tune if you were riding in the Western Cape from November to April. The Devil's thorns (duwweltjies) attacks tyres by the dosyn on every ride. After April I usually replace my tyres as you simply cannot get all the thorn stings out and with hundreds of sealed holes in your tyres it is only o question of time before you have tyre failure.

It does however depend on where you ride as well, but for most races you can expect a few thorny patches along the route.

Very true. Not a lot of devil thorns up here.

That depends on how much jagger is left at the finishline

No.

 

But I agree with Jeep fella, are we really having this discussion ?

We might as well go back to v-brakes.

Hahahaha!!!

 

ok tubeless is more "convenient"

Tubeless does NOT equate to less weight.

 

I have seen far too many tubeless rides ending abruptly.

 

- Lower tyre pressures does not = less speed offroad

- If done with the right tyres tubeless = less weight

- Tubeless = much less time wasted on fixing punctures

Sealant, seals most punctures.....sidewall cuts is another story

With tubeless you put in sealant.....

 

Supporters of tubeless tyres tend to forget that you can put sealant in tubes too. I sometimes run tubes filled with Stans sealant and you'd be surprised what they can withstand. They even seal pinch flats. What's more, you reduce the risk of sidewall cuts and you are guaranteed not to burp. I'm not saying tubes are better, but filled with decent slime, they are nowhere near as *** as the tubeless crowd would have you believe, plus they're a lot cheaper.

Good to see some people still believe in tubes,as I do.I hacve ridden both and prefer the advantage of tubes.Can use cheaper tyres, change them if you need,5 mins before a race. no burping.(as I ride hard with jumps) I prefer higher pressures anyway.Make my own sealant tubes and they seal just the same as a tubeless setup,much cheaper,and easy to maintain.

[GLuvsMtb]

I'm old school. Tubes are good for me. I always carry at least 1 spare tube plus puncture repair kit. I get a puncture and 5-10 mins later I am up and running again.

thinking that lower pressure means increased rolling resitance is an over simplification of the science involved with rolling resistance. A clever guy I know explained to me why higher pressures do not always mean less rolling resistance. To simplify the explaination you need to roll a rubber ball along the ground and have one bouncing on a very high frequency (small bounces over a distance). The ball that has contact with the ground for the longest time will need less energy to get to get from point A to point B and will get there quicker. The longer the distance travelled, the better the rolling ball would do. There is a point in the frequency where the bouncing ball would travel quicker, but unless you have perpetual motion, the rolling ball would catch up and pass the bouncing ball quite quickly.

Long story short, the better the contact with mother earth, the less energy is used to propel yourself forward. This increases with an uneven surface and over longer distances.

How do you add sealant to tubes?

 

I know you can buy tubes with sealant.

Best is to buy tubes with removable cores. Just take out the core and use a syringe to squirt the sealant in. it's a two-minute job.

 

Without removable cores, just cut a small hole, squirt sealant in with syringe, then use a normal patch to seal. That's a ten-minute job.

I used to have slime tubes, worked like a bomb. I now have tubeless and I've had two blow outs. Luckely the second one I did not lose to much air. With the rear I enjoy the lower pressure as it is a bit more comfy.

it's a bit like discussing why we use car with aircon while we could wind down the windows or use mp3 while a cassette player worked perfectly fine or why we use email when fax was awesomely reliable... gee, I could come up with countless of examples now... ;.)
