careening off into the tool boxes. What I found was a pinhole in the rim side of the tube. The rim
tape had sunk into the cutout for the spoke nipple and then opened enough to allow the tube to
contact the nipple head.

I believe the tape is velox, definitely a woven cloth with adhesive backing. I looked it over and
it seems all the spoke openings were dimpled and discolored (kinda brown). The spoke side of each
dimple was littered with what looked like the shavings left after hacksawing a piece of PVC pipe.

I'm not sure if I've got a product problem or a procedural issue.

These are Sun M13 rims, running Primo Comets, 451 x 1-1/8, at 100-105 psi. I built the wheels last
winter and have ridden them 1000-1500 miles.

What are your favorite rim liners, what process have you followed for installation? Did I do
something wrong or miss a step in assembling my wheels?

My favorite - Velox. Thay never failed me.

Brown? Rot?

Could the litter be the glue after some nipplemassage (oops:-)

Suggestion - don´t think long and hard, just replace Velox, patch the hole and keep ridin' (bring
patch kit)

Stuck the wheels on the M5 btw. About 69 cm seatheight but might have to fiddle a little to
avoid it looking like the Dolce Vita or whatever that italian job with the pedals above
noseheight was called.

Something that has worked for me, and doesnt' require a trip to the Bike shop is good ole Duct Tape.
I tear a strip wide enough to cover the spoke holes and stick it in. I've ridden wheels many
thousands of miles with nary a failure. It ain't elegent but it works Denny in Sayre, Pa "Bent but
not Broken"

Velox rim liners are great, but like anything else can wear out. If you replace with velox brand make sure and get the correct width. I've also used filament tape with good results (tip from old cranky lbs owner).

I'd stick with the Velox if I were you.

Its the BEST, in my experience.

Rust or aged lubricant. That's what it looks like on mine.

Typically, if the spoke hole or socket poked a hole in the tube, your rim strip is too narrow. The
rim strip needs to be wide enough (for your M13 rim) to cover the entire rim bed, from bead to bead.
*Many* people (including me) make the mistake of applying Velox rim tape that's too narrow and
leaves the sides of the rim sockets exposed.

Another alternative is fiberglass reinforced strapping tape. It's easier and neater to rip
lengthwise that duct tape, and it's thinner, too. This is an advantage with very narrow rims and
"tight" tires.

The tape was plenty wide, definitely covered from beadseat to beadseat. The discolored dimple and
subsequent hole were centered in the tape.

Tried that as an emergency repair but when inflating to 120psi it blows out. Velox for me.

I had a rash of flats on a ride years ago due to a worn out and broken rim tape. We had stopped to
repair my latest flat in a grocery store parking lot. A mechanic on the ride went into the grocery
store and came back with a roll of 1/2" adhesive medical tape and a 1/2" roll of fiberglass
reinforced strapping tape. He wrapped one layer of adhesive tape and then one layer of fiberglass
tape on the rim. It worked so good, that 20+ years later, I'm still using this technique on every
wheel (lots) on every bike that I own.

Eeek! I've seen Velox tape dimple- but I've never, ever seen a hole or split in the center of the
tape (aside from the valve hole, that is). That's in 25 years of wrenching on bikes.

Perhaps there was a protruding spoke or nipple swarf underneath the hole?

Jeff

Dave, If you are not sure the tape is Velox then I seriously doubt that it is. All the Velox I have
seen has "Velox" clearly printed the entire length of the tape. If your tape does not say Velox then
it probably is an imitation or medical tape.

Velox is my first choice for tape for all of my bikes. Don

Btw Beeblebrox, your webpage seems to have gone titsup. Didn't you break your bananabike into a few
more pieces than God and Optima originally intended? Ever get a replacement?

My ISP have dropped the ball on domain transfer and I've not chased them up about it because
chapmancentral.demon.co.uk seems to work (see .sig). They had some DNS problems this week, which
could be causing issues right now. The story of the bent 'bent is on there - the long & short of it
is that Optima replaced the frame and rear fork without demur, and were very prompt about it as
well. I think I posted this hereabouts, but I could be wrong. It is now electric blue :-)

My rear disc pulled off, and I now have a Hope hub on the back. It's called Obi-Wan, for obvious
reasons ;-)

I also have used duct tape, when I was a kid and didn't care about doing things right. I used to
tear off lil squares of duct tape to put over the nipples (like they used to do in Hollywood), then
I'd put the regular liner over all of that. I don't know why I did it, I just did it. :-)

On second thoughts - curses! You are right! Domino server crashed. Normal service will be resumed as
