My 56cm Langster seems small, do I need a 58cm frame?
(I'm going to apologize in advance for not being able to go to a bike shop and get fitted for a bike. I realize that is the best option and having read threads similar to this before that this is good advice.)
I currently ride a 56 CM Specialized Langster ('08 London because I used to think I was cool). I'm planning on selling that bike for a few reasons (mainly I want a steel frame with a non-sloping top tube that will accept fatter tires since the roads near me are horrific) and building up a new bike with Fyxation's Eastside Track Frameset (https://www.fyxation.com/shop/en/183-...-frameset.html). I'm a little stuck with what to do about sizing, however. My Langster seems really small; I'm about 6'1 with pretty short legs (31'' inseam) and a long torso and so it feels like I'm always way out in front over the bike when I am riding. I mainly ride around town and to and from work (about two miles on flat ground, so nothing major) so the ability to throw the bike around isn't a big deal to me. I'm much more interested in having a comfortable bike that I can ride at a relatively relaxed pace for long periods of time without feeling like I'm really cramped (I'm throwing a coaster brake and porteur bars on the new bike, so definitely not built for speed).
I've purchased both the 55cm and 58cm versions of the Eastside Track Frameset and don't really know which one I should build up. I haven't had too many bikes, and so I'm not sure how the sloped top tube of the Langster translates when measured against the more traditional geometry of the Eastside Track. I've copied the geometry of all three bikes below; if anyone has any ideas about which might be best for me I'd really appreciate any insight.
