Wheels and Weight Distribution
Hi all, I have a pair of Mavic Ksyrium Equipes, (admittedly only used on my other frame, I haven't tried them on the Madone) but I noticed that they didn't feel as stable on descents as my winter wheels (Omega Mach 1), and nowhere near as good as the stock Bontrager Race wheels on the Trek. The Mavics are the lightest of the three, but anything above about 35mph and the front starts to twitch and wobble. I had the spoke tension checked out but that was good. Anyone know why this is happening?
I'm asking because I would like to buy a wheel upgrade. This is because when I really drop anchor, the Bontrager Race wheels have a rather grabby brake track. My first club outing on my new bike resulting in a nice face/hedge interface in front of a concerned motorist.
The Madone has really neutral, predictable handling, and I'd like to ensure that continues. This isn't a thread asking you to recommend wheels, I'm trying to work out whether any lighter wheelset is going to have that same 'flightly' feeling as the Mavics. Thoughts? Is it the wheel weight? Is it my fore-aft weight distribution? Is it just that my arms are too tense?
On a related note, I've noticed that weight distribution seems to come into play quite a lot for me. Every time I read something about descending, someone advises hanging right back on the bike, but for me, this seems to induce front wheel wobble. If I get my weight over the front, the handling settles down. Why is it advisable to shift your weight backwards?
