Dahon Puncture!

Saturday October 22, 2011

Took the Dahon out today as I was spending the morning out and didn’t want (or need) to take the car.  The trusty bike was a great ride as always and the 3.5 mile round trip was very nice on a cold autumn morning.

Back home and the Dahon was placed in the hallway and left whilst I had a coffee.  Shortly after, the rear tyre was completely flat and the bike leaning to one side.  Hmm, a damn puncture.  Will need to take a look at that, but not today…


CrankBrothers: Power Pump Alloy

Saturday January 17, 2009

As I was pumping up the tyres on my D7HG during the week, I began thinking that I could do with a new pump.  I’ve been using the Zorin pump which is in the bike’s seat post but I began thinking of pumps which have pressure gauges in-built which surely must make pumping the tyres an easier task.

I went to Halfords thinking of buying one of the floor/foot pumps but ended up coming out with a CrankBrothers Power Pump Alloy.  With space an issue at ‘Dave HQ’, hence the reason for a Dahon, I thought that the floor pump would take up too much space so the £25 Power Pump Alloy seemed like a good decision with it measuring in at just over 9″ long and 173g in weight.

The pump will inflate up to 130psi which is more than enough for the Dahon’s tyres.  The pressure gauge is a little under an inch in diameter and shows the pressure in both psi and BAR.  My quick tests against a mid-range digital pressure gauge showed that the readings from the pump’s gauge were accurate.

The pump has a dual head which fits both Schrader and Presta valves.  Included in the pack is a plastic case/cover which fits snugly over the dual head and the pressure gauge, keeping the important bits safe from knocks and dirt.  The case also doubles as the mounting fixture should you wish to mount it to the frame of your bike.

The pump works very well.  I deflated one of my tyres and then inflated as a test.  There’s a switch on the bottom of the pump which selects either ‘High Volume’ or ‘High Pressue’.  Starting out I used the high volume setting to get the most air into the tyre in the shortest time.  After a while, it became difficult to pump due to pressure now in the tyre, so it was time to quickly switch to the high pressure setting.  Now I could finish pumping and took the pressure up to 50psi.

The build quality of the pump is very high and it’s backed by a lifetime warranty.  I’m getting to like the CrankBrothers, they make some great kit!  (Previously purchased the Speed Lever for puncture repair.)  So, if you’re looking for a good quality, small bike pump then look no further!

Update, 27th January: I’ve added some photos to Flickr of the pump to show some of the detail.


Puncture Repair

Sunday August 24, 2008


Okay, so not overly happy about yesterday’s puncture but I did manage to get to Halfords this morning to buy some repair kit.

The pump is already in the seat post on the D7HG but I still needed a tyre leaver and a puncture kit.  There were a few choices of kit at Halfords.  I’ve grown up knowing about the little box with the the rubber patches, glue, chalk, crayon and sandpaper – these kits were there.  However, I opted for some pre-glued patches called “Skabs” from a company called Slime.  You get six patches in a little box along with a scuffer.  It’s a great idea and the appears to work well – in next to no time my puncture was repaired!

Checking on the Slime website, they also make inner tubes for bikes which have ‘SLiME’ in them.  Now these seem pretty cool and they’re something I’m going to consider: “Smart Tubes instantly seek out and seal punctures as they occur, preventing flats, repeatedly and continuously for up to two years“.  I’ve read somewhere that the road tyres in general are more prone to punctures so this may be the answer.

The other item I needed was a tyre lever and I selected the SpeedLever from crankbrothers.  No need for three tyre levers, just take this one!  Gets the inner tube out very quickly.

Right, I think that Skab should be set now so I’ll take a look at getting the tube back in and the bike road-worthy again.

It’s a shame it’s raining.


STOP! – Puncture

The Old & The New

The Old & The New

Damn.  Long Bank Holiday weekend, nice sunny Saturday evening and I’m out on the Dahon. 

Sitting in the sun, then I move on.  Cycle through the park, sit down, relax.  Then I move on, sit by the castle.  Then I move inside the castle grounds and relax.  Looking out over the river, the sun getting ever lower in the sky and the trusty Dahon by my side.

Then I move on…

Hmm, back wheel feels a little odd.  Surely I didn’t go over any of that broken glass I passed?  Did I?

Must have.  The back tyre was flat and I was about a mile from home.  A good evening for a slow walk back.

Puncture Repair

Wednesday July 30, 2008

No, I haven’t had my first puncture on the Dahon but I just read a great post on the Dahon website forum.  The topic was in relation to wheeling a Dahon Curve to a bus stop after the guy had a puncture.  One of the helpful posts which subsequently appeared on the forum gave this great advice:

You’re out in the middle of nowhere and a looong, long way from any bus stops. And it’s miles and miles from ‘civilisation’, ie., no help, in any direction. Repair patches all used up, no good anyway, because the pump’s just gone kaput!

So, what to do?

Take the tyre off the rim – no need to remove the wheel if it’s one of those complicated rear wheel combinations – AND pack as much roadside grass as you possibly can into the tyre. It’ll protect the rim and surprisingly, (depending on how much grass you were able to squeeze in and then replace the tyre back on the rim), effective. You will find that you can cycle quite efficiently until you reach help.
