First Pucture

One thing H*lf*rds is useful for....

They do stcik on patches where you don't have to use any separate glues -
just peel off backing layer & stick on. Very useful.

I've been commuting for about 3 months now and yesterday I had my first
puncture :-(. Of course I hadn't got round to practicising fixing a
puncture so I was in at the deep end! I tried my best with the pucture
repair kit (the foil backed patches) but they just wouldn't stick on
properly. Do you have to leave them on for a while before you peal the
back layer off? And yes I had aplied the rubber solution :-P .
So I decided to try changing the inner tube (thanks to reading this
group I had a spare one in the bag!) I have to say I was amazed how
simple it was, despite being the rear wheel. These quick release tyres
are brill! So I now feel like a proper cyclist.

I don't bother repairing punctures at the roadside, unless I get more
than one puncture in the same ride (which hasn't happened since I gave
up using Hutchinson Scorpions). Stick a spare tube in and patch the
punctured one in the warm and dry when you get home (although I don't
bother with this either, these days - I just buy new ones).

The back tyre now has a 1cm chunk/slash in it.

If the outer tyre has a slash in it replace it or else the new tube will
quickly puncture too.

Trick is to leave the solution (actually a contact adhesive, as I
learned here) until it's /almost/ dry, just a wee bit tacky, before
applying the patch. When you put the patch on work the edges with your
thumbs for a while to get it to stick better, and then try and peel the
foil.

If that doesn't work, try a different sort of patch!

As you found changing the tube, it's much easier. Usual strategy for me
is change the tube and then fix the other one when I get home, so it's
now the spare tube.

shirley the foil is on the outside of the patch?

Find hole
roughen with sandpaper
Apply the glue, leave for a minute or so until dry to touch
(examine tire for foreign bodies whilst waiting)
remove foil
apply patch, press the edges down firmly
grind chalk on sandpaper and apply powder to any glue around teh edge
of the patch
Wait a minute or two and gently remove cellophane backing from patch or
just leave it on

best wishes

These patches had foil on one side (which the instructions said to
remove first) and paper on the other which was to be removed carefully
once the patch was attached.

I think as Peter pointed out I probably hadn't let the 'contact
adhesive' dry enough. My fault for trying to patch it quickly. Next time
I will change the tube straight away and patch later. (The tube now
patch later scheme!)

The heading should read puncture not pucture of course :-[

Gourmet puncture repairs, not initially recommended outdoors!

1) First, find a place where you can sit comfortably for half an hour.
Make sure you telephone is either disabled or within easy reach. Make a
cup of coffee/tea and put on radio or music of your choice. Your kitchen
is a good a venue as any. Ideally the air should be warm and dry.

DO NOT RUSH!

2) Find the puncture. If you need to put the tube under water to locate
the hole, dry the tube in the air and/or with a paper towel. Do not lose
sight of the puncture's location.

3) Thoroughly roughen the area surrounding the puncture with emery cloth.

4) Apply a *thin* layer of rubber solution to roughened area and LET IT
DRY. Do not touch it. Avoid getting dust on it.

5) Apply another thin layer of rubber solution and let it dry.

6) Remove foil from patch and apply to glued area of tube. Scratch patch
onto tube with thumbnail until paper or plastic backing start peeling,
then peel backing off from centre outwards. Check edges of pach have
stuck.

You have now fixed that puncture BUT

No puncture repair is complete until the cause of the puncture has been
located and removed. Check the inside of the outer tyre.

Sometimes there is another puncture in the tube. The obsessional might
want to check by passing the whole tube under water.

Decent puncture repairs are best done in batches, at home, on a wet
weekend IMHO.

The most likely reason would be not using sandpaper or similar on the
tube first. I even forgot myself last month when I had the first
puncture in years (modern tyres are great).

As kids, we never used to take the wheel off, just slip off one side of
the tyre and squeeze the tube between the brake blocks.

The tyres I have are continental sports contact tyres. I know if you buy
them yourself that they come with a one year puncture guarantee.
However, my tyres came with the bike (Ridgeback cyclone). Does anyone
know if this guarantee would apply to my tyres as well. Just wanted to
check before I contact the LBS.

I'm sure the guarantee applies. The tyres weren't free, you bought and
paid for them just like any other purchaser, yours just came bundled
with the bike.

If you have any bother at the shop, I can recommend you email
Continental directly, I've had excellent warranty service from them.

I had a set of low mileage Sport Contacts develop a sidewall problem
recently. Emailed Conti via their web page, received a very prompt
reply telling me to send the tyres back for replacement. They quickly
couriered out a new pair, and threw in two new inner tubes in lieu of
my postage costs and faff factor.

Quick, efficient and cheerful customer service.

Also don't test your repair by inflating (by more than enough to
round-out) before refitting the tube.

I'm finding this thread ever so slightly depressing, having just bought a
pair of Sport Contacts for the front end of the trike. <sigh>

Don't worry, I'm really quite impressed by the sport contacts. I have
a second pair in 26" size which I run on a "courier-ified" specialized
hardrock. I've given them some fair welly and they're proving to be
good tyres. Excellent grip on tarmac and very sturdy when I take them
on badly surfaced tracks and trials. They feel nice and fast, yet I
keep running them over glass and other road debris with no punctures
or sign of damage yet.

The ones which went manky (they were 406 size) had some kind of defect
specifically to do with the logo printing on the tyre.

Photo's of them here if you want to see:

http://homepage.ntlworld.com/gareth.evans490/Taifun/Continental/

Sorry, they're rather big, I didn't resize them.

There was no damage anywhere else on the tyre, just the logo area, so
perhaps it was some kind of manufacturing problem with that batch?
Anyway, Conti cheerfully replaced them without quibble.

Ta, and I'm reassured. The ones I've just bought are 406es; Bob Dixon of
AVD said (admittedly as he flogged me a pair ;-)) that he's putting them
on Windcheetahs as standard these days: not got the sidewall problems of
the Grand Prixes I used to use, and noticeably better roadholding. If
there was a regular problem with them I guess he'd know.

If we get a good freeze again this winter I'll be hoping that the
roadholding isn't *too* good - it would take all the fun out!

Crikey! You got a response out of Cap'n Bob? Sterling work!

My Sinister Agents would have us believe that Conti are in any case to phase
out the 406 GP[1] as they got rather badly burned when Schwalbe started
making 406 Stelvios. That was two years ago, though, so they may have
changed their minds.

Thanks Bob for the info. I will contact the LBS tomorrow. 1 puncture in
3 months is probably pretty good going cycling through the Clyde Tunnel
cycle path. I think is is used as a bottle bank!

Cheers

FA use for pressures much over 60psi, IME. Superb for low pressure

Have worked fine on my touring tyres at 80psi, and in emergency use in Tour
of Normandy with 100psi tyres - to get cyclist back on road quickly.
