Sizing for All City Big Block
Currently, I'm riding a Kilo TT (55 cm) and the reach is a bit too big for me. I already shortened my stem but it still feels like a stretch. I believe the effective top tube is 560 mm.
I'm looking at the Big Block geo and am debating between a 49cm and a 52cm frame. The top tube for the 49cm is 535mm while the 52cm is 550mm. Is it better to go smaller and get a bigger stem if it the reach is too small?
A little bit about me: I'm about 5'9" - 5'10" and have an inseam of 30". I have slightly shorter arms (my wingspan is about 5'7"). If anyone could help I'd greatly appreciate it. Thanks!
