Well its the size I got on my group buy frame. Thought it would be nice to be able to use my other stems if I wanted variations, so i got that frame to match. Specs via IRO, headtube sized for a 1-1/8" head set, threaded, 53cm. I hate the look of threadless stems, its just the bots in the back that I dont like. I enjoy the one piece look of threaded stems, how are there none out there in 1-1/8th?
