15 Ways to improve the Tubeless Experience

[Aedon]

1--DAVE'S WHEELS: On tubeless tires that are stubborn to inflate, first remove the presta valve core. When it's out the air chuck engages without a presta adapter. This allows much more compressed air to escape into the tire. After the tire inflates, remove the air chuck and use a finger to quickly plug the open hole in the valve stem. Lift the finger and immediately thread in the valve core. It's easy to do without losing all the air inside the tire; all it takes is a pound or so for the beads to stay put. Then add air to the desired tire pressure.
 
2--DAVE'S WHEELS: Most current tubeless valve stems use a removable valve core. If your's doesn't, Stan at NoTubes will. They offer tubeless valve stems with removable valve cores to fit every UST and converted-to-tubeless rim application.
 
3--DAVE'S WHEELS: Cut a length of drinking straw and slip it over the presta valve and hold it in place with a valve cap. This will keep the threads from getting buggered up. If you have a catastrophic tire failure, it will be possible to easily remove the nut and the valve stem or rim strip. Find something to boot the tire with, use a spare tube and ride home!
 
4.--DAVE'S WHEELS: The way we check to see if the Stan's is drying up is to remove the presta core. Then use an old spoke as a dip stick. If the fluid level is below half the length of the threads (3/16"), use Stan's injector to add an ounce more sealant.
 
5--STAN'S NOTUBES: Always use soap and water or a tire lubricant when inflating converted or UST tires tubeless. This will allow the tire and rim to interface, and for most leaks at the bead to stop within seconds.
 
6--STAN'S NOTUBES: When running tubeless, lower pressures are not just faster. They are also cheaper! Lower pressures increase tire life up to 300%.
 
7--STAN'S NOTUBES: Never exceed 40 psi when inflating a standard tire tubeless or you run the risk of stretching the tire off the rim. Plus the high pressure expands the casing and creates more holes for the sealant to close. If the beads are soaped the will seat at a much lower pressure. Only use enough pressure to seat the bead so it sits consistently around the rim edge. Then check for leaks that need sealing.
 
8--STAN'S NOTUBES: The ZTR Race 7000 Series cross-country rim stabilizes tires as well as most 30mm wide downhill rims. It's due to the extremely short sidewalls and wide internal width. They stabilize tires better than other rims of the same outside width due to the short sidewalls and wider internal width. This means you can run lower pressures without getting excessive tire side roll during high speed turns.
 
9--STAN'S NOTUBES: Tubeless racing air pressures for a pro elite rider weighing 165 pounds and running the tire-volume-expanding ZTR Race 7000 Series wheelset with a large air volume 2.0 tire is 18 to 20 psi in the front and 22 to 24 psi in the rear.
 
10--STAN'S NOTUBES: To classify as a large air volume tire the casing width needs to be a full 2.0 inches wide. Usually the casing width is the same as the tread width. With maximum air volume the tire can be run tubeless and at a lower pressure without reducing stability.
 
11--STAN'S NOTUBES: We talk with so many racers that still tell us they must run 45-55 psi in order to keep up with the pro's. But if I went up to a pro and told him that he must race with 45 to 55 psi he would refuse to ride. Pro riders understand they cannot win using such high of a tire pressure. There is no bump forgiveness, no control; loss of handling stability, and a big reduction in speed over bumpy ground when running pressures over 25 psi. If you insist, then why not just go back to racing a full rigid bike?
 
12--STAN'S NOTUBES: All tires tested at 45 psi then lowered to 25 psi ran 1/2 mph faster at the lower pressures. How do we know? On our tire testing machine we have two 3/4 inch high bumps. When testing a tire at 45 psi then lowering the pressure to 25 psi the lower pressure allows the machine to spin 1/2 mph faster. This is due to the tire at higher pressures bouncing upwards and backwards when hitting the bumps. The lower pressure allows the tire to conform to the bump reducing some of the speed-robbing rebound we see at higher pressures.
 
13--STAN'S NOTUBES: After switching from tubes to NoTubes; subsequently being able to run low tire pressure, riders in a 2 hour sprint test race took 7 minutes or more off their times.
 
14--STAN'S NOTUBES: The ZTR 355 29'er wheel is one of the best kept secrets for cyclecross racing. It has a sidewall that is 1/8 inch shorter than other rims, an extra wide 3/4 inch inner width, and an incredibly light weight of 14 ounces. This cross-country rim gives a huge performance advantage over narrow road rims. It means the ability to run a lower tire pressure without getting excessive side roll during high speed turning. The lower pressures adds to the suspension, traction and flotation in sandy areas. With The incredibly light The Crow 29'er tire, performance exceeds 700c cyclocross tubulars.
 
15--WTB: The drop channel of the WTB LaserDisc rim keeps the NoTubes rim strip from finiding a comfortable fit. WTB sells special, 11 millimeter rubber strips that fit perfectly under the NoTubes strip on LaserDisc series rims. Or try Velox cloth spoke tape under the NoTubes strip. Before mounting the tire make sure that the NoTube's rim strip doesn't interfere with the tire?s bead seat.

I've got 1 tip.

 

Fit slime tubes and remember to enjoy your ride.

Gt Oke. you hate reading ? Then HON (how on earth) are you going to do home schooling? Cause I can tell you that homeschooling is a lot of reading by yourself ...
