LONDON, Sept 7 (Reuters) - Gold dipped on Wednesday, losing momentum due to profit taking following a rally in the previous session on U.S. data that weakened the case for a U.S. rate rise soon.

A string of disappointing U.S. data since Friday "has thrown a real spanner in the works regarding the next Fed rate hike", MKS PAMP Group said in a note.
"We see more potential upside from here with September now looking highly unlikely for rates to move higher."
Commodities analyst at INTL FCStone Edward Meir said the slower-than-expected data on Tuesday reduced the odds of a rate hike in September to 15 percent probability with a December move still around the 50-55 percent mark.
"There is still some scepticism regarding the timing of rate hike after the data," said Carsten Fritsch, an analyst at Commerzbank (DE:CBKG).
"The likelihood for a hike in September dropped sharply and the likelihood in December also dropped somewhat and hasn't risen back to the level before U.S. data."
