However, after hitting a pothole and other various lumps and bumps, i can feel the rim hit the hard object, so i went to pump up the rear tyre more... but i got about two pumps before i couldn't squeeze any more air in due to the amount of pressure i needed to compress the pump! Am i doing it wrong? i have the new multi valve end on the pump so undo the small screw end on the vanve and put the pump on as far as i could then lifted the lever - surely its that easy! So what sort of pump do you guys use to get high pressure into racing wheels? - i have a car foot pump with an adaptor for the small valve tyre but it doesn't seem to pump any air in either! HELP!!! Thanks in advance! ;) |

But i can only get the tyre pressure to around 40/50 (i think) whick when you squeeze the tyre is fairly solid, but once im on the bike it looks half empty! Will have a look in tescos asap - what sort of pump is it though? |

They are base out of Ireland so shipping is fast. you might also consider in getting co2 inflation system just remember to let the co2 out after the ride I been told that co2 can break down the tube. hope this help. safe ridding dude. |

It tends to leak through butyl tubes quicker. After all it is only to get you home, then it is best to let the tyre down and re-inflate with air. Dont worry about it too much, just enjoy cycling!!!!

 Joined: 06 Jul 2010 Posts: 2 Bike: My Profile | Hi Mad Gutts The pump I use is made by Crank Brothers and is rated to 130psi as was suggested on one of your replies. Wiggle sell one on this page: http://www.wiggle.co.uk/p/cycle/7/Crank_Brothers_Power_Pump_Alloy/5360013733/#more Couldnt sing its praises enough. Used several times while out on the road and it really did pump my tyres up to 120psi and could have done more. Read the description on the page address ive given. |

At that sort of pressure you run a real risk of damaging the rim or at the very least getting lots of extremely annoying snake bite punctures. Get the track pump and up the preeusre to at least 100psi plus. You'll notice an instant difference. |
