46t/19t?
 
Anybody out there in gearland ever rode a 46t/19t singlespeed. Any advice/suggestions?

Guess 09-20-15 07:25 PM

I'm on a 46/18 fixed, its on the sort of easier end of gearings but not so easy that my knees blow out while going downhill. If you live in a hilly city like I do, and are not super strong, go for it. If you live somewhere flat, I would recommend, something a big harder.

Thanks guess. I am really just looking for an all around ratio. I was thinking 46/18 but went for a spin on another bike tonight with the gearing at 48/19. Still seems a little tall. A 48/19 is really close to 46/18 in gear inches. i am buying a fixed soon and will mostly be using for fitness. 46/19 I think will keep me pedalling pretty consistently. Which is my objective. So I don't blow out the knees at longer distances in higher gears. Thanks again.

My advice is to keep pedaling and figure out what works best for you. Don't base your choices on what others do.

Thanks almost trick. Just wondering how other peoples ride have been like riding 46/19. Your advice is understood. Thanks again.

Ok, good to hear.

I've been spinning 46x19 for several months now. It seems perfect and I have no plans to change it. I also believe many running higher gears are mashing or over geared. Very few are sustaining 20+ mph for any great distances.

Thanks again almost trick. Your advice and experience with 46/19 is more than likely the way I am going to go. I plan on doing a lot of distance riding and this raToo from my research could be bang on. Your response has been happily received. Appreciated.

AlmostTrick 09-20-15 09:19 PM

Changing ratio's is cheap and easy. Experiment.

If, like me, you know where you spend most of your time on a geared bike, go a tiny bit higher than that. That's what I did and it was spot on.

sunguyto 09-20-15 09:27 PM

I hear ya almost trick. I went for a spin earlier tonight on a geared bike. 48/19. Felt a little tall. Your comment about 46/19 was what i thought would be bang on for me as well. I think I got my answer.

AlmostTrick 09-20-15 09:30 PM

Let us know how it goes.

sunguyto 09-20-15 09:33 PM

Cheers almost trick.

I wheeled for about 30 feet tonight on my moped. It was pretty awesome.

IAmSam 09-21-15 04:29 AM

Are you going to start a new thread for each gear ratio you consider?

Phil_gretz 09-21-15 01:56 PM

I can't wait for the 46/17t thread to begin. 'cause that's what I ride...and, I'd like to say that.

I'll be waiting a while for 45/16 to come up. Maybe I should preemptively start the thread.

We need a gear inches subforum for all these threads.

I'd like to see a widget that converts x/y figures into gear inches, or x/1. Like, hover the mouse over 46/17 and see that it's 72.2 or whatever.

It would also need to know the tire size, since that affects the calculation, but that would be a nifty feature.

I wanna say that's too spinny, unless you're carrying a load or riding against the wind.

Plus or minus an inch, doesn't matter. Still way more informative than some x/y I've never ridden.

TenSpeedV2 09-22-15 08:41 AM

I thought 46:16 was a bit too spinny. I couldn't imagine 46:19. My riding area consists of mostly flat roads however. I really like the top end on my 49:15 which allows me to ride more at a geared road bike pace vs a "fixie."

bones_mcbones 09-22-15 11:04 AM

48/19 is the sweet spot, many skid patches TOOOOO!

If 48/19 is too tall, steroids.

sickz 10-01-15 10:31 AM

67" is great for those learning to skid. but too low to be practical imo.

interestingly upon looking at this chart:
https://www.velodromeshop.net/gearchart5.jpg

i realized it is wrong, w/ gross errors in calculation.

i'm currently at 53x18 which is a tad bigger than 44x15 (previous ratio). you'll see that's not reflected in the chart. hopefully no one uses this one.

this is the better one: http://rideyourbike.com/images/skidspots.jpg
uses the default 27" as the wheel diameter constant as well

IAmSam 10-01-15 12:27 PM

^^^ Surprise, surprise - I too, like that calculator, especially for the fact that it includes odd. smaller wheel sizes. I used it back when I had a mini-fixie with 20" wheels to figure out what-the-hell size rings & cogs to use on that thing.

Mentioned it in another thread - but here is my favorite gearing calculator ATM...
