Wouldn't be a bad idea. The stock Bontrager wheels on Treks is the bike's only minus. One of our sons and I have had six Bontragers, and every single one of the rims cracked in the first several thousand miles, and that was without any loading other than 8 pounds of water, a very large seat bag, and our 130- and 168-pound bodies. We have not had a rim of any other brand crack. Now we're on wheels built by Peter White with Velocity Aerohead and Aerohead O/C rims, 32 spokes rear and 28 front. After the first few years we haven't had any trouble so far, but that shouldn't mean much yet considering they have a lifetime warranty. These wheels are no heavier than the Bontragers either-- just better built.
