'''96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '12 Surly Pacer, All are 3x8,9 or 10. It is hilly around here!
You need two wrenches, one should be a 32 mm "headset" (i.e. thin) wrench to set and hold the top race flats. The second can be a regular 32 mm open end or adjustable to tighten the top nut. Also note that headset nuts and races have octagonal (8-sided) wrench flats, not 6 like almost all other fasteners.
