Tubeless?
Some advice please.
I am looking for a good alround tyre and like the look of the below. Its says tubeless compatible which has confused me. I assumed tyres were either tubeless of not tubeless. Presumably tubeless means no inner tube required. Do such tyres therefore come with the valve attached to the tyre? Are tubeless any good?. Typically heavier and ride not as comfortable in some cases? Any advice appeciated. I am obviously no expert just someone who enjoys on road and off road rides. ========================================= Michelin Wildgripper XLS Pair F&R26x2.1 FoldingUST Green-Blk http://www.chainreactioncycles.com/M...x?ModelID=2151 |

So the tyres are 'tubless compatible' - if you use them with a 'tubeless' rim, they're tubless. Otherwise not. Presumably tubeless means no inner tube required. Yes. Do such tyres therefore come with the valve attached to the tyre? No. The valve is separate, as with a car tyre. Are tubeless any good?. Typically heavier and ride not as comfortable in some cases? The overall weight is lighter (because no tube), and can be run much softer without attracting pinch-flats. Really only for mountain bike racing in conditions where traction is at a premium. The downhillers use them, but they aren't bothered about having to pedal the damn thing back up. Any advice appeciated. I am obviously no expert just someone who enjoys on road and off road rides. ========================================= Michelin Wildgripper XLS Pair F&R26x2.1 FoldingUST Green-Blk Singletrack magazine recently did an enormous group test on tyres, the results of which surprised and interested me. Their findings were, in brief: * fancy tread designs offer little benefit * soft sticky rubber really makes a difference * lightweight tyres were on the whole disappointing Their top picks over all were front: Kenda Nevegal (630g), rear: Kenda Blue Groove (630g), although they had more specific picks for different surfaces. The best of the sub-500g tyres was probably Maxis Larsen TT 1.9, which was rated as sketchy on roots but OK on other surfaces, but at 490g per tyre it's not very light. -- (Simon Brooke) http://www.jasmine.org.uk/~simon/ 'there are no solutions, only precipitates' |

You can use a tubeless tyre with an innertube (if you must) but its less advisable the other way round. Presumably tubeless means no inner tube required. Do such tyres therefore come with the valve attached to the tyre? No, the valve is sealed to the rim. Are tubeless any good?. Typically heavier and ride not as comfortable in some cases? I will not be using them, as I prefer to carry a spare tube and replace a punctured one rather than the faff of having to repair the tyre while out in typical puncture weather conditions. Any advice appeciated. I am obviously no expert just someone who enjoys on road and off road rides. When you have a team manager who says the sponsors want you to ride them, consider 'em - or be a fashion victim. ========================================= Michelin Wildgripper XLS Pair F&R26x2.1 FoldingUST Green-Blk http://www.chainreactioncycles.com/M...x?ModelID=2151 50% off I see - looks like they're not wanted. Tubeless tyres make sense on cars because its not practical to take the equipment to remove car tyres from rims with you on a journey. For most cyclists, they are not sensible by the same reasoning IMHO.

Thansk for the detailed repsonse. I think i will stay away from the tubeless and go with what i know Any idea whats considered a typical/average tyre weight?. I've got mavic's on but ive no idea of their weight. |

Do you have kitchen scales? ;-) Anorak on, weigh tyres, look up others tyres on manufacturer/dealer websites, compare weights, consider what you're getting for that weight and whether you need it, etc. ~PB |

Mavic don't make tyres; they do make (very good) wheel rims and wheels. The average mountain bike tyre is /about/ 600 grammes for a 2.1" wide tyre; the range is from about 400 grammes per tyre to about 900 grammes per tyre. Tubes weigh of the order of 150 grammes each. The lightest mountain bike tubes are under 100 grammes but are said to be more vulnerable to punctures. Obviously narrower tyres are lighter than equivalent wider tyres, but won't be so good on loose/friable surfaces, tyres with fewer smaller knobbles are lighter than ones with more bigger knobbles but aren't so good on muddy or rough surfaces; and tyres which are just thinner are lighter than thicker tyres, but /much/ more vulnerable to punctures. Getting weight off tyres is reckoned to be a good thing, because accelerating the rotating mass is said to take more work than accelerating mass elsewhere on the bike, but I have to confess I don't really understand thy it should be so. Because it's far away from the centre of the wheel. http://www.pumaracing.co.uk/flywheel.htm explains the principles, even though it's car based. 1kilo off the flywheel is equal to 39 kilos off the car in his example for first gear. Most people's legs don't get up to 7000rpm though. |

The stored energy actually doesn't do you a lot of good on a bike, either, since it only adds a little to the coasting distance when you stop pedalling. -- (Simon Brooke) http://www.jasmine.org.uk/~simon/ ;; Skill without imagination is craftsmanship and gives us ;; many useful objects such as wickerwork picnic baskets. ;; Imagination without skill gives us modern art. ;; Tom Stoppard, Artist Descending A Staircase |

And getting over bumps / directional stability. Stop the wheels of a bike that's in the air and it's a lot harder to keep it going where you want. More applicable to DH MTB. |
