I can't keep it up !
I like many have recentley lost my tube virginity and decided to go the tubeless route .
However having overcome the initial problem of blowing the tyre onto the rim bead,I just can’t keep it up !,I’m using stans flows,with maxxis high rollers & stans fluid with superstar valves .Air seems to be leaking out of the spokes !, is this normal ?,or am I missing something ?.
The tyre will initially inflate to 60 psi then goes down …Posted 4 years ago
Tubeless wheels don’t choose who it likes and who it doesn’t, although after reading some of the tales of woe on stw you’d maybe think so.
If it’s coming out of the spokes as you say I’d be looking at the tape, correct width and fitted correctly as per video above and then the valve is it seated right is it tight.Posted 4 years agochrssmaleMember
If the wheels are hope hoops, then the green tape is not the same as the yellow tape. Yellow tape applied as per bruneep link will seal the rim. If you do have yellow tape installed, check its the correct diameter, then at a guess it may be fitted too loosely. Stans tape makes a twanging noise as you stretch it around the rim, though I noticed superstars yellow tape didn’t.
So, assuming the correct tape is installed properly. Mount a tyre with a tube and inflate. Leave it like that for 24 hours to help get a good seal between the rim and tape.
If it still leaks, then remove the tape, clean the rim and try again. Remember to wrap the tape as tightly as possible, ensure its correctly seated as you go and don’t forget to overlap.Posted 4 years agovincienupSubscriber
I was having endless trouble and after paying attention of where the air was coming from it turned out to be the valve.
Superstar valves are fine in Mavic UST’s for me – don’t see why not in a Flow.
Guessing you’ve made a hole in the yellow tape to shove the valve through… It’s not too big, is it? Don’t need the tape on Mavics, but I could imagine that you want the smallest hole possible…Posted 4 years ago
I’ve just converted a Mavic 521 (with stans strip & recommended tape, specialized 2bliss tyre, stans sealant), and the bugger just won’t stay up, gone down 3 days in a row….
I’ll pump it back up tonight, ride it a bit and see if that sorts it, if not, it’s been an expensive experiment!Posted 4 years ago
Finally got around to sorting mine out, bath test revealed lots of tiny pinholes in sidewall (butcher 2bliss), in diagonal rows. Spent 20 mins or more spinning wheel around in various planes to distribute the sealant, then a very short ride, and now has stayed up for over 24 hrs!Posted 4 years agoNorthwindSubscriber
Superstar’s rim tape seems just as good as stans btw. Their valves imo are better- they could be more of a pain to get a tight tyre over but they’ve got a massive “cone” for the base so are less picky about the seal. Think they are the same as WTB ones but about half the price.Posted 4 years ago
