Well had my first puncture.

Fixed it ok.

Have been trying to get slime in the tubes, is there a special way.

The pipe on my bottle seems too be too big so as much comes out the sides as goes in the tube.

Yes the tubes are deflated!

Green snot everywhere.

go tubeless less hassle no flats lighter and can run lower psi.;)

Well I have a £2.99 tyre repair kit that I am patting myself on the back for using.

Not quite done 600 miles on these Rapid Robs so would like to use what I have then upgrade when no nobbles left?

You need to have the type of presta valve that the whole central core can be removed, unscrewed.
There's normally a two flats visible for pliers or tiny spanner below the little pip.

The valve nut is really tight on there, I thought it would break if I turned it more so been trying with valve pressed in.

It could be all one piece? The type that cannot be unscrewed.

In a phrase, don't do it. If you get a puncture with slime in, it'll get you home-and then you need to replace everything because it cannot be fixed.

Get a puncture resistant tyre. Expensive but worth it.

And often not even get you home either, slime often fails to seal since puncture types vary so widely.

Oh, everything green and snotty for nothing.

Ok, I think a spare tube is the only answer then as I was miles from home and it was a side wall thorn that went down really quickly.

Luckily International Rescue 4 was on hand to come and fetch me.

How do you fix a flat in the dark anyway?

by riding it home, accepting the shite handling and extra friction or by leaving it in a darkened place, locking it up, and calling a taxi.

Or by keeping a head torch with you.

In the bad old days when I was running a tube set up, unless the puncture was somewhere obvious, I would just stick another tube in and be done with it.

You might possibly need to think about replacing those tyres though. The Racing Ralphs that they are based upon, are actually a very good tyre and I still run one on the pedal mtb along with a Rocket Ron.
The downside of the Racing Ralph is that it is a very thin lightweight tyre, and suffers from punctures. Whilst the Rapid Robs have the extra protection added, I very much doubt that they are really going to give much protection.
Sadly this is a bad time of year with the hedges starting to be cut, and thorns can be a real issue.
If you don't want to replace the tyres or go tubeless if it is compatible, you could look into buying a more heavy duty inner tube. I suspect that if you are still running the OE tubes, that they are more than likely very thin lightweight tubes.

With your eyes closed.

Once I had the tyre off the side walls are more like canvas than rubber.

They are really strong as I have given them a lot of stick and would quite happily buy them again as they have been so good.

Just the puncture thing brought the possibility of being stranded up.

Another thing I now need to carry is glasses.

Slowly whilst keeping an eye out for doggers

My bike came with knobbly Nicks so I put 2 slime tubes in and after 900 miles no punctures as yet.
Do you need special wheels for tubeless?
I wouldn't worry until you start having punctures. It seems pointless to change unless you need to. Obviously changing has advantages, but I can't really think that you currently need to worry.

If you do decide to change, and your wheel set is tubeless compatible, just make sure that you buy the right width of rim tape to suit your rim.

Your rim is also more likely to use a Presta Valve, not a Schrader as SW has linked to. Check this first before buying anything.

If you do decide to change, and your wheel set is tubless compatible, just make sure that you buy the right width of rim tape to suit your rim.

Sounds like good advice.. but as someon has pointed out it nearly puncture season..
