Yeah it's like going from a 52 front to a 40 front and staying on the same rear cog. Who hasn't done that?

OP, not related. But I have a '94 Specialized Allez Pro, I see yours is a project. What are you doing with it?

I find it pretty amusing that the OP is going through all of this trouble to completely change their gear ratio to something that isn't practical at all and buy a new lockring, because they got a good deal on a $30 cog.

I run a 50x15 gearing on the track when putting in a harder training session, and I would never ever consider running a gear inch that high on the road or even warming up. On the road, I run a 42x15 gearing which is a 73.6 gear inch.
Get a sensible gear ratio on the road, anything involving a 12 tooth track cog on the road is not sensible.

Ok I found a calculator:
I started with 40/16 which is 67.5 (spun it out on the downhills)
Next tried a 40/15 which is 72.0 (was better but not quite right)
Using a 40/14 now at 77.1 (quite comfy with this one)
And I still have no idea what the numbers mean....

Smaller the gear inches, the easier it is to pedal, but is also easy to loop out.
Larger the gear inches, the harder it is to pedal, but is also harder to loop out and makes climbing a royally painful experience.

They mean you're going to suffer terribly going to a 12T cog. Seriously, don't do it.

Your cog is slipping.
They sure do, but how often does someone with a geared bike only use their smallest cog? Shifting gears helps distribute the load placed on a chain over multiple gear ratios.

Nice looks a lot like mine, but with missing parts and purple accents.

Haha yeah, I guess not much has changed really, people are still putting bright colors all over their bikes.
