>>1946563this is a rare and lucky wear pattern. Usually the smaller cogs wear faster, because they have less tooth engagement.
The straight top gears are fantastic to ride.
13-21 is:
13, 14, 15, 16, 17, 19, 21
I suggest you buy a (silver!) shimano 11-28
11, 13, 15, 18, 21, 24, 28
And combine them so that you get:
13, 14, 15, 18, 21, 24, 28
The newer shimano cassettes all start with 11t cogs because of the prevalence of mtb/ hybrid and compact chainsets which have smaller big boy rings. Your 53t ring gives a decent tall gear with 53/13 or 53/12 and those are the gears Eddie Merckx rode. You also have a more efficient, better feeling, better wearing drivetrain riding bigger cogs, as there is more tooth engagement.
This kills every bird with one stone. You get fresh cogs for the ones which are worn, hill gears, and retain your fredly retrodouche time trial ability.
Your short cage derailer should shift that cassette too, maybe with the b-screw flipped around, and if it doesn't, any other will.
Custom cassettes are underrated for older drivetrains. At the very least I like to swap 11t cogs for 12t just to get that one 1 tooth step at the top end. The top end steps on wide range cassettes are practically chasms for riding fast on the flat. They are awful. Having decent low hill gears should be high priority for most bicycles, but I also love close steps. Obviously you can go to expensive 11 or 12 speed systems to get this off the shelf now, but you have a decent custom gearing staring you in the face. Don't continue with your retardo straight block as is, unless you plan to solely fang the bike hard on a flat circuit
>>1946565>The posts above are a perfect example why boomers need to fuck off with their outdated dogshit techThe most confusing part of your bullshit is that anon has a hyperglide cassette and dual pivot brakes, he has a funcitonally modern bike. To boomers it's not even classic. .
