Got a few questions, if somebody could take a minute to help me out I'd appreciate it!
I have this old rigid mountain bike (26", 18sp) that I'd like to make a fixed gear with 700c wheels. Been doing a lot of reading up on the process. Want to avoid buying another frame.
The bottom bracket is 73mm, and the rear horizontal drop out spacing is 126mm. Also it seems like I have enough clearance for a half-inch wheel radius increase from 26" to 700.
I would like to replace my crank with a single-chainring (and some 165mm arms) - will I need to change my bb also, or can I just take off my current crank and put on a new one?
IF I have to change my bb, Is there a budget one that fits 73mm?
As for the rear, if I buy a wheelset with flip flop hub, is it likely that it will be possible to space it out to the right size to fit, or are some axles shorter and some longer? Is this a non-issue? I also want to use quick releases, and I have one already on the bike, can I re-use it with a new wheelset?
Any idea what the dimensions of this bike are gonna do to my chainline? Wondering if the wide bb will cause the sprockets to need to be spaced pretty far from the hub to get a straight line. In this case, maybe a 126mm dropout is advantageous...?
Thanks y'all, and as all newbs must say, sorry for the dumb questions. Tried my hand at the search for a few minutes, but felt like it wasn't gonna turn up the answers I was looking for, at least not onces I could understand.
