I have a brand new Seven ID8 with full Campy Record. I'm using the 2007 Campagnolo Record Ultra Torque Compact Carbon Crankset 50/34. I have about 700 miles on the bike since I got it in the Spring. This week I started to notice a suptle "gyroscopic" type feel which has gotten a little worse with each ride. I spent my entire ride today trying to trouble shoot the cause. I cannot feel when I'm coasting at any speed so I think that eliminates the tires, wheels, etc. I've narowed it down to when I'm putting a significant torque on the cranks. Maybe 200+ watts or so I begin feeling a "gyroscopic" whine from the cranks as I turn the pedals. I do not get this when I am just spinning at low watts, only with some significant force on the pedals.
Any idea what could be causing this???? I have a 135 mile event this Wednesday and I'm concerned I could have a mechanical problem. Any input would be greatly appreciated. Thanks!
