A seatpost yoke is the clamp assembly under your saddle — hardware you never look at but carry on every ride. Stock alloy versions range from 28.9g to 83.1g. Replace with titanium bolts + carbon base + 7075 aluminum yokes, and the heaviest setup drops to 20.3g.
Stock yoke hardware is overlooked because you never see it. But it sits at the highest point of the bike — weight here affects handling more than weight at the bottom bracket.

FAQ
Will sweat corrode the yoke hardware?
Saddle clamps sit in the drip zone. Stock alloy yokes and steel bolts corrode slowly. Titanium bolts eliminate galvanic corrosion. 7075 aluminum yokes with hard anodizing resist sweat far better than raw or painted alloy.
Does installing a new yoke change saddle position?
Same rail clamp geometry as stock. Saddle setback, angle, and rail spacing are unchanged. Remove saddle, swap yoke hardware bolt-for-bolt, re-mount at existing marks, torque to post specification — roughly 10 minutes.
