I have to agree, not only is the effort high but the benefits low.
- can’t run a high enough pressure
- tires cost more
- still have to carry spare tubes
- messy to deal with
- really need to use a limited number of wheels with the specific rim
- maybe the tire won’t go down as quick
- lower weight (doubtful once you take into account the sealant)
- less pinch flats (I normally only get those when I hit something hard, once every 6-12 months)
- less rolling resistance (but compared to the normal pressure I like to run would most likely be higher than non-tubeless)
If I am going to go to all that trouble I may as well run Tubs. Can carry an old tire as a spare under the seat instead of the saddle bag, so about the same weight.
Show's you really have no idea what you are talking about.
The point is that you can run lower pressures... more comfort,better handling, lower rolling resistance.
Tyres aren't cheap but are no more than some other top end tyres.
Yes a spare tube is wise to carry.
Only messy if you need to put a tube in ...pretty rare.Mounting them is no mess if you know what you are doing.
They can be used on any rim with minimal set up. Though setting up a valve on a 50mm plus rim can be an issue.
THe tyre will go down slowly...if you get a big cut it will go down fast.
They are always heaver than a normal race tyre and tube combined...even before adding the sealant.
Zero pinch flats...nothing to pinch, more a mtb thing but happens on the road.
In all tests I have seen the rolling resistance is always less than any tubed tyre...and comparable with tubulars.
No they are not for every one... but get your facts right.
