I have a road bike and avoid potholes at all costs where possible, the ones that catch me are the ones I don't see or are hard to see. Also I'm not sure the many speed humps on my route help. I try stand to 'soften' the speed humps, I bet both my tires and ass appreciate that

Anyone else experiencing more than average punctures on joburg roads. Flippin' hell seem to get them almost weekly. Luckly got Gatorskins. My flats have been pinch punctures, all the potholes from the rain I guess.

Oh BTW you can pop onto the Polar site and download manuals for the different polar devices. I suggest you download the cycle computer manuals to see how things get installed and operate. This will give you an idea of what model you're looking for in terms of Polar device.

I thought the Polar computers/sensors were wireless like their watches. If the cadence and speed sensor are wireless then you should be able to buy a polar watch for around R900-R1700 and it should work with the sensors. Plus I assume you'll want a heart rate chest strap to work with the watch. If the sensors have wires running to the computer mount on the handlebars then it looks like you have to get the specific model of computer that fits the mount. I assume it should be a standard mount to the different Polar models of cycle computers (I assume the Polar CS200 or CS400 computers.) If you need a cycle computer I'm not sure you'll find one that is being sold new or 2nd hand that doesn't come with the sensors. You can always pop into a Sportmans Warehouse and see what they have in terms of Polar, you should be able to get someone at SWH to crack open a Polar watch/computer box to see if things are compatible. I usually get sales people to open the box anyway before I buy stuff to make sure everything is in there.

I've been riding for a few months and do about a short 9km morning ride on some quiet roads in my area. Haven't had a problem until this last week where I had a puncture on two days. Lucky I was on my was back home so didn't have to push very far. I've realised that I probably got these punctures from underinflating the wheels, and had pinch punctures from all the new holes in the road due to all the rain. Got a floor pump now as the little hand pump just doesn't (or maybe I couldn't) get 7 bar. Also got a saddle bag for the patch kit that I never took with me. So I'll use the co2 for flats on the road and the floor pump normally. Also right now I don't ride very far so maybe going the threaded route is ok.

Finally found one at Cajees (eastgate, fourways didn't have) and one at morningside cycles. Cajees had the cheaper option.

Found some by phoning more people. The problem I see now is that I can get a threadless adaptor for between R185 and R299 while a treaded adaptor starts at about R50. Suddendly saving money on the R7 threadless vs R17 theaded co2 cartrigde doesn't seem that much. Only after 11 co2 cartridges does the threadless co2 cartridge setup (price of adaptor + 11 cos cartridges) start being cheaper on the long run. From what I've seen the threaded adapters are smaller than the threaded ones which require a cartridges cover. What do you guys think?

Phoned 5 or 6 shops here in Joburg so far and none have. Will try a few more...

Marius, where did you buy this? Did you order it from the US? I was hoping someone local would have a threadless compatible co2 inflator.

Thanks. Checked the site and the only thing they have that allow you plug co2 cartriges into are pellet guys Maybe having co2 cartridge on the road is a good idea, you can use it to inflate a tyre and then use it to shoot any bugger trying to rob you hehe...applezunepod2008-02-06 03:27:08

Hi, I did a search of the forum and didn't find a answer so I'm posting. I'm looking for a CO2 inflator adapter that works off the unthreaded co2 cartriges, these are the same co2 cartriges that one puts in bb/pellet guns. My logic is that the bb co2 cartriges cost R7 each up the road while the threaded co2 cartriges cost R17, R20 or R25 in the cycle shops. I tired a few cycle shops but all they have is the threaded type. Anyone know where in joburg to find these? BTW I'm using a road bike (7bar), so 12mg co2 cartriges will do from what I'm told. applezunepod2008-02-06 03:05:20
