Today I practised my bike walking technique and learned some things.
Probably good training for the 'Puffer.
It started as a nice ride on my 1x1. The idea was to ride to the 'Puffer track, do a lap and come back. Nothing difficult, just to get my legs back into singlespeed mode.
On the way was a nice wee bit of road - Jamie knows it well, we've taken his lovely Mercian down it a few times on a 'road' ride - but it was a trifle soft.
Then followed "shite alley" where the path goes past a byre usually ankle deep in you guessed it for 50 yards - and why I love mudguards.
A bit further on to the place of a strangely evolved form of humanity
I have always wanted to see what one of those 'elderly walking children on a bike' looks like, but they are extremely elusive.
But anyway, back to my bike walking...
I had got somewhat past the halfway point when I felt a jolt from the rear wheel. Rim strike, oops! Tyre had a slow leak. No problem for the well equipped cyclist with a frame bag and a saddlebag with tools, you would think. Including 2 pumps, spare tube, and 2 puncture repair outfits, so obviously ready for anything, including the apocalypse.
First problem. Tyre and wheel thick with ordure - where's my wee ziplock bag with latex gloves and bit of paper towel for one's own ordurous emergencies, wounds or the handling of greasy chains?
Nup, not in either bag. Ah, of course, last time I used the 1x1 for a substantial ride was the SSEC and I chucked everything out that was excess weight.
Damn, had to clean it off with some vegetation and bare hands, unpleasant job but necessary to get all the crud off from around the hub because of all the little nuts and bolts to be undone on a drumbrake singlespeed.
So that done, where's the wee spanner for the 8 and 10mm nuts? Ah yes, I remember now. So that I'd never forget it, a few months back I'd had the brainwave of putting it in the wee bag with the latex gloves etc which I always carry. Oops.
Ah well, no problem really. The obvious culprit was the Schraeder valve. Just before coming out I'd added some air and it had been difficult to inflate. The pressure had to get up to about 80psi before it would depress the valve. It felt like it was sticking, so I'd pulled it out, checked it and put it back in, but still had the same problem. However with the track pump I was able to get it up to 20psi with a bit of grunting. Maybe it had leaked.
Anyhow with an unremoveable wheel I figured I could take the valve out of the spare tube and swap it over. That's when I lost all the remaining air from the rear tyre which had been still rideable with care, but of course was now totally flat. Still no problem, until...
I tried to inflate it it with the pump attached to the bike.
It was a nice tiny wee carbonfibre thing that weighs a poofteenth of an ounce that I'd stuck on for the SSEC to replace the heavy old Giant pump I normally have there. That's when I remembered I'd intended to change the rear tube for a Presta for the SSEC and never got round to it. The bloody thing was Presta only.
Just as well I had a spare pump in the frame bag, eh?
Nice shiny Lezyne with double ended hose, so good for both, and I normally use it for my road bike. I spent about 10 minutes frantically pumping away like a teenage boy with his first 'adult' magazine but bugger all air was getting past the valve. Same hassle as the original valve, it was needing about 80 psi to budge it. In the end I got the tyre with just enough air in it to support the bikes weight.
And that's when I started my bike walking training. i didn't want to go back the way I'd come because that would mean walking through ankle deep delights.
Two and a half miles and several barbed wire fence hops later I was at the bike shop in Strathpeffer where I bought 2 new tubes with Presta valves.
The tyre hadn't gone down further, so obviously it was a slow leak. Curious as to how long it would stay up, I borrowed their track pump.
Suddenly there was no problem adding air and that's when I realised what the valve 'problem' was.
The Lezyne pumps (including my track pump) do not have the wee nipple to press down on the Schraeder valve.
And the tale ends with me taking the tyre to 30 psi, sprinting home on the road. The tyre did lose some air but got me there.
And the lesson. Check, don't assume.
