I just built up a Rob Roy and had the LBS install a CK headset. Here's my problem: when I ride, there's a gyroscope feeling in the steering. It feels like there's torque on the fork and front wheel that sometimes fights against the way I'm going. The CK instructions says that that new seals will produce some resistance in the first 50-100 hours of use. Is that what this is? I don't know if it matters, but I'm riding 23mm Continental Ultra Gatorskins. Thanks.
