Do you check your hubs on your wheels to see if the bearings are adjusted properly? My Mavics are the ones that got me thinking about it since you have an adjustment tool. I'm not a big fan of Mavic hubs but that tool they give you is convenient. I even checked my grandfathers wheels on his hybrid for the heck of it. They are Bontrager SSR and when I used the cone wrenches I discovered that those things were really tight, I actually had to put a little muscle into loosening them. The spin a lot better now and have no play and I was just wondering if I was on the right track?
