I have a Road Morph too-- I never have problems getting up to 110+psi. I always get asked at the beginning of a ride (while testing tire pressure) if I need a real pump, lol! But I always refuse because this pump works so well. Just wanted to throw a kudos in: the other day I noticed the pin that holds the little folding foot was gone! So I contact Topeak customer service (by email) to ask where to order a replacement from. Customer Service asked me for my address and promptly sent me a replacement pin and foot-- free of charge. I would definitely recommend them.
