Hoosier make drag racing tyres (that I am aware of), I reckon that those decals have been applied in homage as it were.

That needn't be a bicycle rim, does have pretty thick looking spokes.

Through closer inspection, its possible the decal could have been added. But i would I would like to locate some if they do make them.

Hoosier do lots of tyres for speedway and drags. Not sure about this. I reckon just painted on.

Basic bike mechanics. Pretty embarassed to ask TBH. But I'm going nuts.

Installed a new Veloflex Master 23, on a well used (but never braked on) cxp33, with veloplugs, on the back of my fixed.

First time with a latex inner. Got it to 80 PSI, then after 5mins the inner blow out the side. Figured it was installation error.

Second time with a new latex inner. Got it to 60 PSI, all well. The next day I topped it up, and it went bang again in the process.

Last night I chucked the spare butyl inner from my saddle bag, and gave it 50 PSI. Came down this morning and it hard blown over night.

Pretty sure the veloplugs are installed tightly, although they where ripped out when I looked this morning. So it has to be a faulty brand new tyre, or a faulty old rim. If I get hold of a new inner I may re-install the tyre, moved 90 degrees around the rim, and see where it blows.

Which is most likely at fault here? Brand new Veloflex, or used cxp33 with pristene sidewalls?

PS.

did you talc the inner tube before insertion? they are notorious for pinching when being installed, talcum powder can help with this

otherwise it sounds like there is a sharp bit, have all the tubes burst at the same point?

Cant feel any sharpe bits. I use latex inners for all my skinny tyre needs, so I'm pretty good at installing them usually. I'm going to mark the point tonight, but I'm pretty sure its the same spot. Actually stood watching the bead separate, and the tube slowly start spilling out, before releasing the air. So its definately something to do with the tyre/rim interface.

FFS!

On new rims, tyre explodey business if often down to a bit of weld that hasn't been machined out of the inside, just under the bead.



I can imagine a very small bit of weld, or even just road gunk, might have been lurking there for a long time waiting for a sensitive tyre.

Definitly appears to be something like this. The rims have been fine for a few years. Plus the tyres are brand new.

I'll check tonight. Cheers.

Sounds like the bead isn't seated properly on the rim and/or the tube is trapped under the tyre.

Can't imagine how else the tube could lift the tyre otherwise. Possibly the new tyres have a little kink from storage.. You definitely need to be noting where they blow each time.

I know you know and do this, but i) put a little air in the tube before fitting the tyre; ii) halfway through inflating the tyre go around the rim and squeeze both sides of the tyre twixt thumb and forefinger to free it from the rim and ensure it is properly seated; iii) compare some constant detail around the tyre with the rim to visually confirm it is evenly seated.

Check the tyres really carefully too, even if they're brand new blowing them off can fuck the bead.

thought this may have been the cause of blow-out number two. As I left one side of the bead fitted, chucked in a totally flat inner, and pressed in the remaning bead. Bad technique. But I was looking after the kids at the same time.

Nothing visible. But the bead isnt at prominant as I'd like maybe.

Going to have one last attempt at this. Checking everything. Marking rim, and reversing the tyre (which will mean switching my sprocket over, as I'm anal about these things).

Cheers folks

I have three with massive tears in. Probably centered around the NDS bead area (although thats tricky to see), about 140 degrees away from the valve. I think its the same spot each time. But I'm not sure as it only the third time it happened that I realised this. The wheel is still on the bike as I found it this morning. So I'll look at the area again.

Trouble is I mounted the tyre at the exact same spot each time to line up tyre logos with the valve.

If its the rim thats warped or has a damaged bead lock. Then I'm upgrading to XR200s and droping 80g per rim.

More the bead I think.

The hole is a big rip.

I noticed missing Cveloplugs. But I'm guessing these got ripped out by the blow out. Plus a missing veloplug would'nt explain the time I actually had the inner bulge out the side in front of me. Without bursting.

Sounds like a pinched tube. After putting on the tyre go around it pushing down to make sure it's definitely seated fully in the rim the whole way round, then inflate it very slowly to begin with.

I agree.

But 3* times!!!???

The third was a thick butyl tube. Looked fine at say 50PSI. Went in the work room the next day, and it was blown.

Pixies I reckon.

Pointy eared bastards fecking with my bikes......

(*I managed to realease the air before the tube blow once, so 4 times)

I recon you've got a tiny hole in the rubber on the bead, when the tube is inflated the bead sticks out the tyre and catches the tube.

Or at least I had this happen to me once with a similar set of occurances (took me for ever to find the hole and work out what happened)...

Interesting. Gonna have a proper look when I get back.

I'll leave some pixie traps out tonight just in case.

I would say it's the rim tape, but you don't have any. Are there any other tiny holes in the rim apart from the spoke ones? I had some too narrow rim tape on some generic Ambrosio rims which have a few small holes near the edge and I got a puncture while my bike was sat in my house as the tube was slightly touching one.

Smallfurry, as an aside, if youre having trouble with veloplugs falling out, one layer of electrical tape all the way keeps them in. I actually used a layer on the inside as well and cut little slits in over the spoke holes, the veloplugs sat inside the holes tighter that way.

I've got 2 chain tools, but I've forgotten which works on 3/32 and 1/8, and it seems they've been discontinued.

This one and this one

I think the first one can do both with the adjustable screw underneath. Is that right?

Thanks.

The lack of a lock ring is throwing me a little, there seems to be a lot of thread showing and the difference between too tight and just right is quite broad.

I asked this on the secondary lock thread, but that doesn't see a lot of traffic so I'll stick it here as well...

I know they're not particularly recommended, but does anyone know of a relatively light chain that stands out from the crowd? I'm thinking of something around the size of the Onguard Mastiff or Hiplok Lite.
