Yep.
1. The problem is NOT the brifters.
2. The problem is NOT the Ultegra calipers. Dual pivot brakes are very strong.
3. The problem is NOT the brake pads. Kool Stop makes good stuff.
Unless something is broken or defective, that leaves the cables and housing and how far the pads are from the rim. Or the pads are hitting the rim at some weird angle, that could cause the problem too.
