I have never heard a non-explosive puncture which was quite so loud! Luckily it waited until I got
home rather than going when I was rolling down one of my favourite hills at a shade over 40mph
this evening.
Cause of problem: torn rim tape. The higher pressure overwhelmed the feeble blue cotton tape causing
a beautiful textbook spoke-hole puncture, so a new and stronger brand has been installed thanks to
the infallible Bob Bristow Cycle Rescue Service (only available in Reading).

I can sympathise.
I was just out the door for a ride tonight when I realised the front was utterly flat. Investigation
(my first ever puncture LOL) has revealed the rim tape appears woefully inadequate, in that it's
slipping so it's not covering the spoke holes properly, and that's how the tube punctured... I've no
idea what tape to use as a replacement - looks like cheap plastic stuff in there at the moment - and
I presume it would be worth replacing the rear as well at the same time?
Oh, and glue-less patches. Are they pants, or is it me? Recommendations for a decent patching system
that works (and on spoke hole punctures as well as t'other sort) would be nice, as things to
consider with rim tape.

Velox cloth tape. It's your friend.

Personally, I like the Park Superpatch, which is a breed apart from other glueless patches IMO. Bear
in mind that most glueless patch users are probably using them at MTB pressures, though. I'm not
sure gluesless patches are designed to cope with the rigours of 120psi.

I'll second the last bit, while recommending Leeches for anything up to 70psi and advising anyone
who cares to listen to avoid glueless patches like the plague for pressures over 70psi.
My own experience with Park patches, though, is that they're about as much use as a fart in a
thunderstorm.

Leeches .. most excellent .. ;)

Ahhh .. dunno if Leeches woiuld work at road bike pressures, I use them on a mountain bike .. ;)

Yes, I had similar expiences with the MA3 rims - welcome to the world of 'rim tape matters now and
then'. I was using some cheapo thin rubber stuff when I got mine. I've now got some other plastic
stuff in there now that I salvaged from another rim. Sometimes cheapskates never learn :-)
Patches? Takes a lot to beat a good old fashioned repair kit IMO.

Glueless patches are, in my experience, slightly less use than a chocolate teapot.

Rema Tip-Top are good, the main thing is to follow the destructions - especially leave the glue to
cure for the recommended period before applying the patch.

? If you need to fart while there's a thunderstorm, it's as useful as a fart at any other
time, surely?

Tufo make tubular clinchers that don't need rim tape, they need special sealant for punctures up to
2mm - But are much more puncture resistant than clinchers.

Velox cloth tape is good (16mm should do for MA3 I think). Bike Ribbon and Michelin make adequate
plastic tapes.

Yes if it's similar.
> Oh, and glue-less patches. Are they pants, or is it me?
They are pants compared to proper patches - but they can work sometimes. Ok to carry around as a
third emergency option. The first two options are spare tube and normal repair kit. Tips (for any
sort of patches - just a couple of tips, not complete instructions): sand area on tube well first.
Press patch down very firmly and wait a while afterwards. Do not test repair by inflating tube
outside of tyre (although a very few psi is ok to round-out the tube before fitting).
> Recommendations for a decent patching system that works (and on spoke hole punctures as well as
> t'other sort) would be nice
Any ordinary patches and rubber solution from bike shop, or Velox supplies from:
www.mwdyason.ltd.uk/shop.asp?no_category=2&text_company=TYRE%20REPAIRS%20a nd%20ACCESSORIES
(post free). Either the 15mm or assorted patches would be fine for most punctures. They also
have the rim tape.
If anything has made a hole or split larger than 3mm then it's best to cut your losses and bin the
inner tube.

I'm inclined to agree about glue-less patches. They seem a good idea - small pack size, no messing
with glue - but fail (I use Park Tools variety) regularly at high pressures. They also go all
wrinkly when you let the air out of a tube.

Velox. All other rim tapes are Works Of Stan.
Park glueless patches have worked well for TWFKAML[1] in the past, even at 100+ psi, but tend to
unstick eventually, to the discomfiture of all. Personally I have no trouble with ordinary boggo
patches and rubber solution.

Well, armed with Velox tape (about 14mm from the looks) and an apparently decent repair kit (Rema
Tip Top)I replaced rim tape and repaired tube (just to see if a) I was competant at it, and b) the
repair kit did what it was sposed to) in less than 10 mins. Having remembered I had the rear wheel
re-trued recently I phoned shop and was advised they would probably have replaced the tape, checked,
and they had indeed (initially I thought it'd involve taking rear wheel off with all that entails,
but no, luckily).
Shop had used some new tape - vinyl coated fabric apparently that fills entire width of rim, they
commented that velox cloth holds water when it gets wet, which I can imagine not being such a good
thing. Velox was very easy to apply so will be staying in there till such time as it needs
replacing, at which point I'll decide whether to go with this other stuff or not.
Never bothering with those glueless things again, was much less hassle using the vulcanising
glue stuff!
Now perhaps the bike's not upside down and in bits strewn across my livingroom floor, I'll get out
on a ride tonight!

If you need to fart simply for relief of pressure then yes, but if the fart coincides with a rumble
of thunder then the sound is likely to be drowned out, greatly reducing or even eliminating the
comedy value, and hence making it of less use :-P
