3 years today.
Feels like 8 though.
What have learned in that time? Not a lot.
I still don't know what cadence is, I don't understand the difference of different size cassettes and chain rings and I can never seem to adjust my rear mech myself.
Apart from that, it's been real man.
These terms are musically related terms although you'll find that cassettes have gone out of fashion and been replaced by digital recordings.
See, all you have to do is ask!
