Help the Old Man
Greetings!
Last year I purchased a new Bianchi Pista. It came with the standard 48 size chainring (TruVativ Elita ISIS Drive) and 16T rear cog. Being over 50 years old and just getting started back into biking, the gearing is too tall for me. So therefore, I need to change the gearing. Is it easier to change the crank chain ring to a smaller gearing, or should I leave it and change the rear cog? You comments, thoughts, and opinions are greatly appreciated.

Dont' worry, an 81 inch gear is too big for many youngsters as well. Personally I'd change the cog. A 20 tooth would give you a 64.8 inch gear. If you don't have a gear chart handy here's a link. https://home.i1.net/~dwolfe/gerz/

you need fewer tools to change the front chainring; an allen wrench vs. a chainwhip and a lockring wrench.
you may also need a chain tool so you can shorten the chain.

If you go to a shop, it shouldn't cost more than $30 for a new cog, and maybe $20 for labor if they're meanies, especially if it's the shop that sold you the bike.

changing the chainring is easier to do yourself if you're short on tools. another good gear calculator is https://sheldonbrown.com/gears/
i'm pushin' 40 (years) and 65 (gear inches). recently decreased from 70 inches, and enjoying it very much.
