Will muni help or hurt me?

You sure can! In fact due to the lack of trails in my area (and my lack of drivers license) Most of the time that I’ve spent riding my muni has been on concrete.

I ride my muni on the road (or bike paths) probably more than I use it to ride muni - not for a lack of trails, but because I use it for short distance transportation given it’s a lot more forgiving to ride than my road specific uni (and more fun to play around on).

What MUni is it?

Just an old nimbus 24. The funny thing is it has a custom wheel with a KH rim but a square taper hub. I think it might just be old enough that ISIS wasn’t popular yet. Its probably be pre 2009 as it came with an old style nimbus gel.
