I am thinking of new wheelset for my trek 5000 with is 3 years old and has 3,500 good miles on it. Ultegra group with original Bontrager Select wheelset. I am hearing pings and noises now and wonder if now would be a good time for some new wheels. I am 185 # 56 yr rider that does about 1,500 miles a year , a metric a month in summer for long ride. my tire of preference has been 25mm width.. I don't want to spent a fortune on wheels but don't want to skimp as well.... thats my story ..
