Miche Pistard - constant punctures

No pinching any more, just issues with pressure. I gave up and requested a refund, can't be arsed with tight-fitting tyres when repairing a puncture on the roadside. Sod 'em.

Refund on used wheels that's a bit cheaky. Your puncture is not resolved. If your tyres are a tight fit buy some 17mm wide tubeless tape and use that instead of thick rim strip. Thus will make a huge difference and you will be less likely to pinch a tube. Also unless you know where the hole is you will never resolve the issue. Try a different tyre, conti normally fit miche wheels without difficulty. There is nothing wrong with miche wheels it is just you have not resolved your problem. Also sealant will seal most punctures.

I am using Conti tyres...

No pinching any more, just issues with pressure.

So you were pinching the tubes when fitting?

What's the pressure problem?

I can only assume I was. The last time I fit the tube and tyre, it didn't puncture (so no pinching issue) but when pumped up to 80psi, it simply went down after 5 minutes. A new tube too.

That sounds an awful lot like you pinched it. Were you using levers to put the tyres on?

this thread is rapidly becoming cycling's most notorious case of inappropriate pinching decorum, perhaps second only Sagan...

Have experience of this on a rear Pistard, was getting regular punctures. Every time I looked the rim tape had moved and exposed the rim, punctures on the inside of the tubes. The wheel now has that rim tape, another hard plastic rim tape and some electrical tape for good measure. No more punctures, but there is something off with those rims.

As I said fit tubeless rim tape 17mm and tour problems will go away. Also if the tyres are tight get some flat thin levers. Many levers seem designed to pinch inner tubes.

We will be using fond de jante rim tape on our Miche wheels and aren't having these troubles.

Maybe try an adhesive tape as it won't move, exposing the spoke holes?

Same issue here with pistards. 2 different kinds of rim tape, the second one 16mm velox, 2 types of tyre (vittoria corsa, conti supersonic). All installed by hand. Rim tape moves with time exposing spoke hole and 3 punctures so far. No solution yet and not what you want on the banking. Never had this issue with any other rim

What about Veloplugs?

Interesting response from the uk distributor when the wheels were sent back by my lbs.

In summary they say fabric rim tape is not suitable for a clincher rim used on a banked track and that only high pressure tubeless rim tape such as that made by ryde or schwalbe is to be used and more interestingly I quote
“Incidentally, we would never recommend clincher tyres on a velodrome for this very reason; they are not strong enough to handle the G-Forces and cornering loads as well as tubs.”

Seems to go against uk velodrome policy but there you have it.

Every bike in the hire fleet at Glasgow velodrome has fabric rim tape and clinchers.

Tell them they are talking arse.

Yes smells of corporate bs to me. Have bought some edco tracksport roches and hope to have better luck

I had a pair of Miche Pistard wheels for my first velodrome bike. After suffering a total of 7 punctures from both wheels always on the inside of the tube and regardless of trying different ( and even two) rim tapes I could see that the root cause was a manufacturing fault that was not rectifiable. The fault is that the holes drilled in the base of the rim (for the insertion of the spoke nipples) are staggered to the point that some actually nick the sides of the bead seats and thus cannot be fully covered by a rim tape, leaving a small uncovered crescent with a sharp edge. Apply some pressure and the inner tube will find the exposed crescent and its edge bursts the tube. All of us who have experienced this have tried different rim tapes and (wrongly) thought that they may have pinched the inner tube. I personally had a rear wheel puncture when I was about to get on the bike at the velodrome and witnessed a front go this morning at Derby Velodrome - the rider pumped up his tyres and sat down awaiting the start of the session, minutes later the front wheel punctured right next to us. When we removed the tyre it was exactly as described above. After 6 months of problems I’d had enough and took my wheels back to Halfords who, readily agreed that the problem was indeed a manufacturing fault and made a full refund on the spot. I switched to tubulars which don’t come off the rims if they puncture on the banking. The mechanic at the velodrome told me that they had seen this problem a number of times with these rims. There is no way I would ride these wheels on the velodrome and the greater concern is that someone riding them will puncture and involve you in a crash. Remarkably, none of the punctures I experienced actually happened on the boards.

Just use wider rim tape.

Sadly it’s not a matter of tape width, a rim tape needs to fully cover the holes and it cannot do that when the drill has nicked the vertical surface of the bead seat.

@Paul_Churchill agree the drill holes are too close to the sides of the rim . I don’t think the ridges at the edge of the rim well help either.

Do you mean the rim wall? I don't understand.
On the Pista set we have (and some DT Swiss rims) the holes jump from side to side.
I just measured it and bought a tape (Condor own brand) that fit snug from wall to wall and never had a problem on either set.

The well of the rim is basically flat, each side of the well there is a slightly raised bead seat. The job of a rim tape is to completely cover the spoke holes in the well, when a spoke hole leaves no horizontal rim material on the outside edge then the rim tape cannot do the job of resisting the tube pressure. I never said that all Miche Pistard rims exhibit this fault, nor am I bad mouthing them, I use their chainsets and sprockets. I was a machine tool engineer and I have a degree in mechanical engineering, both of my wheels and the one at the velodrome yesterday had this problem. If the rim tape cannot fully cover the hole and sit in the well then you will get this problem. The rim tape must sit below the bead seat level else the tyre will dislodge it when the beads move onto the bead seats as it is pumped up. The most likely cause of this is the use of a dual diameter drill in a single operation [to reduce time and manufacturing costs] rather than first drilling the large holes radially at right angles to the well and then going round again with the small diameter drill and at the angle if the spokes.

Thin high pressure rim tape will sort that out with no effect on tyre seating. They are a budget set of wheels with narrow rim tape thrown in as an afterthought.
I see what you are saying but I have come across lots of cheap wheels(and some expensive ones) with wonky holes and swarf, as long as these are cleaned and covered there are no issues down the line.

Do you speak for Miche on this ?
You are clearly saying that the rim tape supplied by Miche, the manufacturer, is not fit for purpose. Why would Miche [ a Michelin company, I believe, who have a wealth of tyre fitting experience] do that ?
I'd like to hear the response from Miche

Why would Miche...do that ?
