Bike Lust is straining my (human) relationship

[Trek420]

To echo the excellent advice above, +1 on the counseling and talking. In terms of the bike consider wheels.

My namesake, the Trek 420 was Trek's bottom of the barrel entry level road bike. It got me back into riding. Gradually I upgraded small stuff; saddle, handlebars, bar tape.

When I rode it off the path, over a small cliff and into the creek bed (don't ask ) I needed new wheels. I got the best rims I could afford at the time; Mavic Open Sup Pro. My LBS said it would make a huge difference and hot diggity it was like a whole new bike.

Later as the chain, der, showed wear I upgraded the power train from the original Tiagra to Ultegra. Again, my LBS said I'd notice the difference of the stiffer spline drive and again he was right.

Same entry level bike.

I loved that bike.

I especially loved the whiplash effect it had on riders of "Oh, a Trek 420, whatever ..... woah! But with Mavic wheels? "

Today I have a full custom, hand made, Italian steel, made for me by the man whose name goes on the frame blah blah blah road bike. But I still miss that ol' Trek.

It was how I learned about bikes, upgrading, making decisions based on cost/benefit. It was a hoot to ride and confuse other cyclists "WTH? I got passed by a 420 .... one with Flightdeck?"

So if you like the fit keep the bike, consider upgrades. It can be less ... or even more expensive But don't ride it off a cliff to get them.
