Tech Questions Answered

I'd like to get a comprehensive list of threads going here. The idea would be to send me the tech questions you have and we'll provide an answer in a usable form which other Bacchetta owners can use in the future. This can be anywhere from Bacchetta specific items to latest cutting edge items like E-assist, electronic shifting, etc. (we won't have the answer to all of these, but we probably know someone who does!).
 
So if you have tech questions, post them here and we'll see about getting this started!

    What is the difference between a 650b and 650c tire?  I'm interested in the Panaracer Palesa 28mm tire but it only comes in a 650c.  Would I run into a problem with my Ti Aero or CA3?

    650b is an ISO 584 whereas the 650c is ISO 571.  They are not interchangeable.

    I attempted some `self help' when it came to understanding what `ISO 584 v ISO 571' means and I came up with this: https://cyclocamping.com/blog/2015/08/01/what-do-size-markings-on-bicycle-tires-mean/
     
    Having been trained in the interpretation of the Rorschach test in psychological testing it took little time for me to realize I had not even a hint at what the hell `erlebnistypus' meant.  I still don't.  
     
    So ... what does `ISO 584 v ISO 571' mean?

    My foul-up, it is actually ERTO and is an international standard and in this case for bicycle wheel rim diameter. If you look at your 650c tires, they will most likely have the size molded with 571x23 or something similar. A 700c will be 622x23 where the 23 is the tire width in millimeters.  You cannot mount a 650b tire on a 650c wheel, it will be too big
     
    650b is typically used for mountain bikes but more recently has found favor in gravel bikes.
     
    About a third of the page down on this link is a table that shows the various ISO sizes and the tires that fit.

    Thanks, Tim.  I've been confused (for years) and too lazy to do much about it as it relates to tire sizes.  About four weeks ago I took the advice of an experienced cyclist acquaintance and went with the 28s.  I ordered what he recommended.  It made some mighty gnarly road much smoother.  Today, before a ride, I inspected the sidewalls and came up with: 650 x 28c.  And then, further along the sidewall: 571.  
     
    So I ordered two more of the same when I got home.
