Strive to learn as much as you can and need them (the LBS) as little as possible.
I intend to do just that, and I can thanks to the great advice I get on this forum.
Specifically, I think I’ll change the chain and rear cogs sometime before spring. (if we get a big snowfall, I’ll have the LBS do it then). Then I’ll get a gauge and perform regular maintenance and checks on the chain, replacing as needed.
Thanks again to all for your help.
