Hi all
I am very new to cycling. I currently have
this pump (Topeak Mini Masterblaster) My Giant OCR2 has (I believe) presta valves. Now it seems in the configuration I got it in the pump is not set up for this valve type. However it says on the website that this pump is easily convertable between Presta and Shraeder.
My question is thus: How do you convert? I did not receive any documentation or spare parts with the pump.
Any help would be appreciated as at the moment I have a very flat tyre onmy bike.
Thanks in advance
