I think it's a good option for those who want to maintain a certain speed without needing a high cadence, but depending on the crown, knee strengthening may be necessary to avoid knee pain and adaptation time.

Speed go vroom, but impractical in most applications
The high torque on your knees comes from accelerating and stopping. If you get up to speed and stay there, no problem. If you’re riding that around in stop and go traffic, it will take longer and more effort to get a higher ratio up to speed.
What’s the crown?
Unless you’re on a velodrome I would say its probably not a good idea. Some people like to mash huge gears on the street cause they think its cool.
The smallest cog ⚙️
I really don’t understand this. I have one bike set up with a 13t with a 32t chainring and another with 39t x 17t and another with 48t x 21t. All of them is close to the same gearing. It’s good to use a 13t if you are trying to keep a smaller chainring for a better ground clearance.
I like small cogs. I have a 12t cog for when I want to go hard on the trainer.
I run a 13/36 on my daily beater. Almost the same as my 17/48 just more clearance.
I swear some of yall don’t know what actual bike riding is. It’s about endurance and the ability to ride long for me. 51:17 or 3:1 is a sweet spot for me to hold around 23mph at 95ish RPM which I can sustain most of a long ride with no issue, but still be able to pinch it up hills. To me, the 600w to get it going is about the max I’m interested in. I’d be at 1000w on the ratio you are mentioning and that’s just stupid unless you’re on a real track.
The whacky setups and stupid ratios remind me of the guys that build Harley’s just to bar hop, not actually go on real riding trips to fun winding and hilly roads. That’s just my opinion though, do whatever you want to bring yourself joy. Even if it’s not practical.
What’s your FTP? Because if it ain’t about 4w/kg or 350+ you’ll never use that gearing to its potential, how would you be able to even think about reacting if someone accelerated rapidly.
Pair it with a 60T chainring for the ultimate in knee murdering speed!
Not really useful unless you’re on the track or run a comically small chainring to accommodate
My knees hurt just looking at it.
Hills are already enough on my 16t cog. I don’t hate myself enough to use a 13t.
Everyone is talking about gear ratios, so I’m not gonna weigh in on that. Another thing to consider with a cog like this is that you have fewer teeth engaging the chain more often with more force involved and that’s going to mean more wear. It’s not the biggest deal in the world, and quality matters to how it shakes out but ultimately if you’re putting up a lot of miles in stop and go traffic you’re going to wind up replacing it sooner rather than later.
By itself, I’ve got no opinion about it. It’s just a single part. It depends on what chainring and bike you’re pairing it with and what kind of riding your doing.
It’s fucking retarded on the street. Those who run it on the street just have a big ego or are dumb
Don’t understand the question. The cog teeth number means nothing without knowing what the chainring is.
I would avoid anything lower than 15. To increase the gear ratio I would put a bigger chainring honestly. Unless you are limited by clearance.
Small cogs are less efficient due to more friction, and wear out the chain and themselves faster.
Regarding super high gear ratios, for velodrome only they are ok, for street riding not so much, they become impractical and if you ride a lot might lead to injuries.
ran 52:13 before i knew any better and decided a spinny gear is more fun in traffic
was fast as fuck tho
Just get a 40 tooth chainring and you’ll be fine
went to a 15 one time and it took my knees like 2 months to recover lmao
