i'm in tokyo right now and i've been searching for a keirin frame. i'm 5'10" with a 33" inseam and most fitting guides point me to a 55/56 c-t frame with a tt around 55. i line up perfectly for a 57 c-t frame on dave moulton's table.
i found a nice 56.5c-t araya on e-framebank but it has a 57cm top tube length. this seems like a really long tt for me. the next closest frame to my size is a 54.3c-t, 54tt vivalo. both have seat tube angles of 76* i've scanned the forums and most people recommend a track bike slightly smaller than normal road bike size.
should i go for the smaller bike and compensate with a longer stem or get the bigger bike and hope i'm not too stretched out in the drops?
