The AHH fits me, as far as I can tell using stack/reach/STA/HTA and my current cockpit length on a 21" 1988 Schwinn Voyaguer (the 21" is 53cm C-T which is the same as a 52cm C-C AHH). However, having medical problems with carpal tunnel in both hands I need to resolve. If the AHH is still available in the end of June, let me know, I'm interested.
I would not need the bars (I use drops, the RBW noddle or Compass Radonnuer) brake levers, and the stem is way too long, and I the tires are not road type and too big.
But still interested if available end of June. Can you send a picture of the headset area. Looks like you have an extended steerer tube.
