Plain-language definitions of manufacturing terms used in RFQs
Deflection (squirt)
Deflection is the amount the cue ball deviates from the aimed line when side spin is applied. Lower front-end mass reduces it, which is why low deflection shafts use a lighter or hollow first section.
Pro taper
A pro taper keeps the shaft close to one diameter for most of its length before tapering to the tip, giving a slimmer bridge and a more consistent stroke than a European taper.
Joint pin and collar standards
Common cue joint standards are 5/16-18, 5/16-14, 3/8-10, 3/8-8, Radial and Uniloc. The pin must match the collar in the butt or the two parts will not seat.
Wrap types
Wraps are the gripped section of the butt. Linen, leather and synthetic sport wraps add grip and absorb sweat; wrapless cues expose the wood or carbon and are preferred by players who like a smooth feel.
