I've never been to Loveland or even Colorado, but are the descents twisty with a bunch of sharp turns? If the hills are just long high speed descents with out much braking I'd get a pair of Chinese rims.
You should come visit us. I live by the foothills of the Rocky Mountains at 6,000 ft. elevation. It's a cycling paradise. 8% sustained climbs are quite common here. For example, I live next to the Pinewood Reservoir climb. It gains 1,258 ft. in 3.0 miles for an average gradient of 8.0%. I do this climb several times a week, on my regular bike and on a tandem. Here's the Strava link to the climb http://app.strava.com/segments/638603
The most famous climb with a twisty descent is the Flagstaff climb in Boulder. To be honest I have only driven up the climb. It was featured in the Pro Challenge cycling race two years ago. It gains 1,978 ft. in 4.6 mi. for an average gradient of 8.0%. It has over two dozen turns. Here's the Strava link http://app.strava.com/segments/626263
The Flagstaff climb was used in numerous brake and carbon wheel testshttp://www.eecycleworks.com/VNJune%20BrakeTest.pdfhttp://www.bikeradar.com/us/road/gear/a ... now-41027/
