While putting air in the rear tire of my 6 year old Bianchi, I noticed two hairline cracks radiating out from a spoke hole several spokes away from the valve stem. On close examination, I also found another crack at a spoke hole four spoke away. While the wheel still spins true with no hops, my LBS advised me that the wheel was unsafe to ride (I figured this was the case).
I find this to be very odd. Has anyone else seen this before? The wheels are 32-hole Mavic CXP21s laced to Veloce hubs with straight guage spokes. The bike has a little over 10k miles on it.
Anyway, I just ordered a new wheelset from Performance since my shop didn't have ANY Campy compatible wheels and no CXP21s to lace onto my old hub. The wheels I ordered are Mavic Open Pros in silver, laced with butted DT spokes to 32-hole Record hubs. I know it probably sounds silly to put such nice wheels on a mid-level Bianchi (celeste Veloce) but the bike is nearly perfect and still rides like a dream.
The shop was at a loss to explain the wheel cracks. Does anyone have any idea what caused them? Any comments good or bad on my new wheels? John
