I finally got around to replacing the seat post on the A2R. I found a used Thomson 26.6mm on the cheap, reamed and honed out the seat tube, and crammed the Thomson down in there. Works great..
I own one of those 1998 Schwinn Mesa GSX’s in the next size up (17″) and I like it. I use it for my rain trainer and night-time single track bike as it is outfitted with a dual Cateye light system.
I did a comparison with my Cuda Comp today. It also measures 26.64mm deep into the seat tube and uses a 26.4mm seat post. It looks like a 26.6mm Thomson is just what I need for upgrade.
