So I've decided to either get an IRO or Bare Knuckle frame. I'm leaning towards IRO, but the geometry just seems kinda wack. I normally ride a 50-52 frame. IRO has a 50cm with s/t 46 cm and t/t 52. The t/t seems to be the correct number, but that s/t number seems awfully small. If I move up to a 53cm, it has a 49cm s/t and a 54cm t/t.

It just seems weird that theres such a huge difference in length of s/t and t/t. My old basso frame has a 51cm s/t and a 52cm t/t which seems just about right. The Bare Knuckle on the other hand seems more reasonable with a 50cm s/t and 53cm t/t.

Anyone see any reason why the IRO seems to have such a long t/t in relation to the s/t?
