Altitude and topography affect engine performance. A lot of folks put their location in the intro thread, but it is not in their profile. Somebody has to do a lot of searching to jolt their memory about "who is where...." Giving answers and solutions could be a lot easier if we could just look in the upper right of the side of a post and see "where the heck are you !? " Aussies can give fellow Oz'ers better advise because we in the states don't know the little quirks, (much less the metric system and local tool-lingo), a Canadian will come forward with faster advise for a fellow countryman. If I see somebody within 3 hours ride, I can give particular directions to a decent bicycle shop, (because there are ONLY 3, the rest of the bikeshop guys are jerks). Some simple recommendations that work on the coastline are a no-go up in the Rockies or Sierras, because other tweaks are needed. It only takes a few seconds to edit your profile and add your location. Another benefit of editing, it makes meeting up with an MB neighbor a lot simpler. Or the local MBexperts may get more involved in helping you in your pursuits. Just a suggestion.
