Specialized Allez Sprint Lower Headset bearing

A while back I bought the replacement headset bearing kit (part # S192500001) for my first gen Specialized Allez Sprint. The kit came with 3 size-specific lower headset bearings, and since I only needed the large one for my 58cm Allez, I figured it made sense to pass the other bearings along to someone else who could use them (especially given the Sprint's noted ability to chew through these expensive, proprietary bits).

My understanding is that this headset bearing is specific to the rim brake and track models, and won't work on the disc brake-equipped Allez Sprints.

I've made a guess as to what sizes the smaller headset bearings correspond to, but have also provided the overall diameter below for confirming compatibility with your bike:

Lower headset bearing: 49.6mm (guessing that this corresponds to sizes 49 and 52)

This measurement includes the small bottom lip of the headset, so should be equivalent to the diameter of the bottom of your bike's head tube.

Please message with any questions.
