What am I doing wrong?
New Campagnolo Vento wheels/hubs
New Campy Veloce cassette
New Park BBT-5 Cassette lockring tool http://www.parktool.com/products/det...4&item=BBT%2D5
Torque wrench w/ 1" socket; 0-140 Newton Meters (N-m). The socket has 12
indentions internally, while the BBT-5 has 6
Description per Park :ITEM # BBT-5
Freewheel Remover / Bottom Bracket Tool
Fits Campagnolo® cassette lockrings and Campagnolo® Record™, Chorus™, and Athena™ bottom brackets. BBT-5 uses a 1" hex shape, and will fit the FRW-1.
Acc to Branford Bike:
"Use a Park BBT-5 Cassette lockring tool to install or remove any Campagnolo cassette lockring. The BBT-5 tool also fits Campagnolo Record and Chorus bottom bracket cups."
Directions from Campy are to tighten to 50 N-m.
Directions from Park:
Cassette installed on hub by hand easily.
lockring tightened easily w/ fingers finger tight
HOWEVER HERE IS THE PROBLEM: When Torque wrench applied to 20 N-m, it slips; cannot tighten further past 20 N-m.
Any suggestions? The lockring is new; does not appear to be stripped.
Do I need a socket w/ only 6 indentations?
