I am debating whether or not to go tubeless on my new 575 and whilst appreciating that they may be difficult to setup initially was wondering if anyone has had any bad experiences or can offer any advice on rims/tyres. A mate of mine sent me this link which it quite a convincing little clip uk.youtube.com/watch?v=rhEJYqFw9to |

I've used tubeless (UST) on Mavic 819 rims on my old 575 and am using them on CrossMax ST's on my new one. I've not had a problem with them to date and found them easy to mount and inflate using no more than track pump using both Schwalbe and Maxxis UST tyres. I use 60ml Stan's injected through the valve in each to help ensure some puncture protection and I haven't had any problems whatsoever. For me converting to tubeless has been 100% painless - go for it!

Sorry Tribegranddaddy, but UST tyres weighing a ton is an outdated generalisation  Some of the early UST tyres were heavy but the newer generation of tyres (e.g. the Maxxis LUST range) are certainly comparable to normal tubed tyres. My 819 rimmed Pro II hubbed wheels weighed 45 grams (each) more than my DT 4.2 rimmed Hope Hoops, IMHO that's not a bad price to pay for the extra grip and reliability. You can save a small amount of weight by using a 'tubeless' with normal tyres but then you take the risk of using tyres with sidewalls designed to work with the extra stiffness the tube gives. Personally if I'm worried about weight I prefer to go for a dump before I ride, that's usually guaranteed to save me carrying a few extra pounds ;D Tim |

UST all the way. I've only ever used tubeless tyres on my 303/ASX/4X, mainly Maxxis and Michellin tyres with a bit of 'Just Riding Along Wheel Milk' to make them seal easier. They're sometimes a bit of a pain to get fitted when brand new as the tyres usually have a few kinks in them where they've been folded in the shop.
I've just started using Maxxis Crossmark tyres on my ASR too (in the last 3 months), and I've had no problems using them for XC either. So I guess I'm fairly pro-tubeless........

the point of keeping the weight of your wheels low is two fold firstly the less rotating weight the easier it is to pedal and also accelerate out of corners up slight drags etc the second point is the less unsprung weight you have on your bike i,e, wheels the better your forks + shock will work and the easier it is to set up same so as you can see there are a number of very valid reasons for having the lightest wheels as possible and also the lightest rotating weight your point of having a number 2 before riding is also a valid point but there is a whole different set of sceince and physic issues covering that point

I've had UST for about 3 years now, I've tried DH bikes and XC bikes. My 575 is on mavic 819, I have a UST Conti Vert on the back, and a Maxxis lUST Highroller on the front. Awesome set up. Why have tubes? points to tubeless... - I think it can be lighter, or as light as a regular set up- if I was to run tubes, I would have to get tyres with sidewall protection, snake bites are a thing of the past if you run a nice pressure.
- Thorns! No more punctures- put some wheel milk in, and if you get a thorn, it plugs its own hole, it quite often happens that you repair a flat, and find 4-5 more thorns in there. Flats do still happen, but not at the rate they used to.
- You CAN still get flats, you can still rip the side wall, fitting can be a little hard, and you need a good track pump.
- The Feel with UST/tubeless is better, you get more tyre deflection over bumps, it will give you more grip.
- The Conti tyres I use weight the same than their tube brothers, so I gained no tube weight!
- Its just better! Small downsides, but think of the tube system, its easy to pinch the tube when refitting a tight tyre I think thats a big downside, but everybody is used to the 'risk' so does not even see it as a downside anymore.
