The importance of tyre pressure

by **ksd** on Wed Jul 11, 2007 7:03 pm

I was a bit unsure as to whether to buy the 30 pound A-bike pump first, so i opted for an electrical one i got from ebay for about 4 pound. £30 pound is a bit steep, may have gone down now, not sure. But i did notice a considerable difference when i pumped them up to 90. also i had noticed the tyres becoming a bit deflated when people would have a go on my A-bike. Keep pumping.

Yes it should be fine. I e-mailed support at Cyclaire.com and they say that it sounds like a very rare fault they had in a few early production models and they'll repair or replace the pump for me.

Today I found out why I was having such a hard time with the tyres: the Cyclaire pump I've been using has developed a fault where it leaks air, so it cannot go above about 20 PSI, no matter how much I pump. Naturally I assumed I wasn't attaching it to the tyre properly, which is why I was fighting enough to tear the tubes at the valve

Oh well, "we live and learn", as they say!

Do you recommends Cyclaire pump to use with A-Bike? I just ordered a Cyclaire pump for my A-Bike

I use this pump to inflate my A-bike's tyres.

For some reason, I found it very hard to fit my Cyclaire pump to the valves - I had to push very hard to get it on enough to pump. It can also be quite fiddly lifting the right-angled valve away from the wheel to do this.

In my experimenting I pulled too much on the valves and tears have appeared where the valve is attached to the inner tube.

It's my own fault - I've ordered two new tubes (ouch - expensive) and I'll be more careful next time. Just to let you all know: because the valve is not attached to the wheel (eg with a locking nut), it can be pulled out too far where it snags on the edge of the hole in the wheel that it passes through.

I'm sorry to hear about this.

Anyway, thanks for sharing your experience. I'll be careful when I pump my A-bike next time.

The pump is Topeak Pocket Shock DGX.
Perfect hermetic pumping is possible.
And the ebay price is USD 32~40.

Use a normal bicycle pump is okay. But I suggest you to buy a pump with a pressure gauge on it which can pump the tyres up to the correct tyre prssure.
