Logical choice.

Taking the Pro Logic design and using semi-sealed cartridge bearings, Ritchey's Comp Logic Threadless Headset is a workhorse headset for any of your straight 1 1/8" headtube bikes whether around town or around the crit course. Machined alloy construction and a smaller upper bearing keeps the weight low, and deep cups ensure a secure install for seasons of hard use.

Semi-sealed cartridge bearings. 30.2 mm stack height. Compatible with 1 1/8" head tubes. S.H.I.S. measurements: EC34/28.6 upper, EC34/30 lower.
