    I ride a conversion fixie and i have a 52/14 gear ratio. It's ok riding up steep hills, but impossible to control my bike going down steep hills going into lights or intersections. I would like to be able to do things like sit down skids and wheelies, but it seems a little immpossible because of my heavy gear. Am I just being a pussy, or is my gearing to high? What would some people suggest as a better ratio? Thanks

    These two threads should help you. Long story short, you're gearing is pretty damn high if you want skid and slow down going down hills.

    thank you so much that was very helpful. did u end up going with the 46/16? could u still smash, or did u have to pedal too fast?

    Nothing wrong with learning to spin, its actually a lot more fun than mashing

    haha im sorry greg im a little new your gonna have to explain that a little lol

    I did end up going with the 46x16. I do live in a hillier terrain, so it's perfect for climbing huge hills and descending--very easy to skid with. And I think what Greg is saying is that it's good to have to spin really fast. The faster you can spin the better your cadence, the faster you are overall.

    Oh, and you could get a front brake just in case.
  4.  
    o ok definitely i think im gonna go with that. Since youve already done the research, what are some good front chainrings and rear cogs that i can buy. what are yours? any complaints or regrets?

    I got the sugino messenger crank and chainring, will probably upgrade to sugino 75's in the future (since people say it's almost a gold standard) and I have an Euro-Asia Cog on the back. That's what I have and what works for me. Maybe you can find something that suits you better.

    Steve Bell posted this in my other thread (2nd one I sent you).
    http://software.bareknucklebrigade.com/

    Definitely check it out. You can play around with the gearing and it'll calculate how many gear inches, gain, and number of skid patches. Type in your old gearing and type in a new gearing you may want and compare them.

    Cool thanks a lot i saw that in the other thread and checked it out. Thank you so much for your suggestions. If anyone else has any other advice i'm trying to learn as much as i can so let me know!

    You should try talking to other people that bike in your area (seems like there would be a lot where you're from haha) and get their opinions. They do bike on the same terrain as you.
  6.  
    haha yea thats true the reason i stareted geting a little worried was because someone who I rode with told me i was crazy for riding that gearing with no brakes, and then i was wondering why i couldnt sit down skid or stop on hills when people who were much less experienced riders than me (hard to find) could do all that shit.

    Well, skidding is a little tricky to get down at first, but like with everything else once you get it down you have it for good. A lower gear ratio will definitely help you achieve your goals. Just because it's "lower" doesn't mean it won't kick your ass at times. So don't worry about this. From what I've seen, for the purposes of riding around the city, whether it be sprinting around and racing people or just meandering about, people tend to stay in the "lower" gearings. The high forties. Those huge gear ratios are more at home on the velodrome where you don't have to worry about going through intersections and getting run over by cars.
  7.  
    yea thats what i figured i already have normal skids down but they're a bitch haha especcially cuz i dont have a bike with the geometrey for that. The big concern is being able to slow down coming down hills.

    Are you resisting as you go down the hill or are you bombing down it and then try to stop. Part of riding a fixed gear is anticipation and planning ahead.
  8.  
    I try to stop the whole way down because i know how dangerous it is without a brake. Sometimes I even have to walk my bike down hills. I'm an extrmeley careful rider when it comes to things like that.

    Good. Cause in the end of the day, personal safety is key.
  9.  
    haha yea exactly, do u think if i brought my gearing to the 46/16 it would fix my steep hill problem?
    • CommentAuthortangsuto
    • CommentTimeMar 12th 2009
     
    You would have to spin a lot more that's for sure. However, it's also a lot easier to resist. You can have your legs go "gumby" a little more, you can back-pedal more effectively, and you'll definitely be able to skid a lot easier. So yes, I do think it'll help. Hopefully others respond to the thread with their opinions.
  10.  
    Yes definitely the problem with going down hills for me is that the high gear makes it really hard to backpedal so i was thinking that if i put it in a lower gear, i could reisit and skid or skip a lot easier
  11.  
    Personally, I find a front brake works wonders when it is on the bike for function rather than not on the bike for fashion, particularly till you get the hang of fixed riding, but that is just me.
  12.  
    Yea stinky i c what you mean, i've been riding for a couple months and consider myself a competent rider, i just feel like the only thing holding me back at this point is my gear, because the only times i have trouble are on steep hills, and if i can solve that by changing gears, then thats how i would want to do it, i've been riding like this for a while and done well without a front brake, and can't think of a time when i would use it other than these hills, and that kind of seems like a waste of $70 or so to me, but i've definitely thought about it.
  13.  
    Learn to "ski" down big long hills. Back n forth in a very tight pattern, dipping hard between pedal strokes. once you get the hang of it, you will be able to controll your speed much better, and feel better running big gears. I think a 52 16 is simply too big for street riding though. you will never learn to spin, and it will take a toll on your knees mashing up those big hills at such a low cadence.

    Save your knees and spin to win! I go with 42/17 with all kinds of skid patches and low gear for keeping under control in the city..

    ^ that's what i'm currently spinning on too at 42 x 17. It's a bit slower than higher gear ratios, but skids are wayyyyy easy. Im planning to go to a 44 or 46 sometime soon, but that'll be later on. As far as slowing down on hills, try skipping to slow down first and bust a quick whip skid. At first i found that putting your foot on the back tire helps too! haha Stay safe and wear a helmet.

    42 is crazyyy small.. 49x17 ftw. When going down hills, its all about foot retention, slow yourself down, and let it fly down hills

    Hopefully that can show a greater picture and comparison of gearing ratios. Just use it like a multiplication table.

    I would actually like to see Big Bird riding a fixed gear. Just saying, that it would be a sight. I mean a six foot yellow bird isn't enough of a sight, but a six foot bird on a bike. Good times I feel.

    well riding around with 45/16 is not very smart, but theres no way I would ever ride around town with a 52/14.. Your looking at both extremes . Pick something practical , yet somewhat challenging .
  20.  
    yea exactly thats why im thinkin 46/16
  21.  
    I would go a little bigger, if you want a good all around gear. I think people find that a 48 tooth ring is ideal

    i too have a 52 chainring, and for riding in the city and in the hills, my unconventionally large 21t cog is perfect. i have combined this with very short cranks so that i can spin faster to get to a higher top speed while maintaining a high level of control over speed. i would suggest anything between 19t and 21t for that chain ring if youre looking for a lot of control, but be aware that youll be giving away top speed and slow spinning for that.

    well a 52/21 is only a 2.4 ratio, which is actually easier than the 45/16 at 2.8 .. So yeah dont run a 52/21 either . If your keeping the 52 on, I'd say run a 18 cog, giving you a 2.8 ratio, same as a 49x17 which I think is ideal.
    • CommentAuthortangsuto

    I think what might come off as confusing is what deermatt pointed out. Just because you get a bigger ring, but have a bigger cog also doesn't mean your ratio is any higher. It's actually a combination of the two. Bigger ring and smaller cog makes your ratio go up.

    So what I think deermatt is saying with his example of 52x21 vs. 49x17 is, what's the point of having a huge ring and huge cog if it's actually easier than having a combination of the smaller 49x17 which is actually harder and faster (what I believe is more of what you're looking for)?

    my ratio is very low, with 23s tires its around 65 gear inches. i thought he was looking for a lower ratio for more control, and with a ratio this low, i can maneuver adeptly at my whim through traffic, perfect for me. the problem with such a low ratio is a low top speed for some people, but i have short crank arms. though they make pedaling harder, they allow me to spin very quickly which lessens the top speed problem. if youre looking for more control, try to look for something at 70 gear inches or lower assuming 165mm crank arms, but there is no ideal. beg, borrow, and deal for a variety of used cogs because no one can say use this and dont use that. find whats right for you!

    if the ratio is the same, the ratio is the same, of course, haha, but there are very subtle differences. with a larger combination of the same ratio, itll be smoother, quieter, and more durable while giving up a little weight. i must say my drive train is absolutely inaudible, and i like the look of a large chain ring as well, but my cog is uncommonly large because i like a low ratio. however, whether you want to go larger or smaller on a given ratio shouldnt be an issue now. i suggested finding your perfect ratio by working around the chain ring because its easier to change out in my opinion, cheaper, and for many conversions, the largest ring cannot be removed.

    In response to adriano, I agree with what you said about there being subtle differences with larger and smaller combinations of the same ratio. I was just trying to clarify a little more of what deermatt was saying for the orginal poster, because honestly, looking at all these different numbers can be pretty confusing.

    I also agree with your statement about how to go about finding the right ratio, and that finding the "right" ratio is more important.

    Like with everything, it's all about finding what works best for you.
  22.  
    45 x 16 is optimal for me for city riding. Acceleration and deceleration are both quick. 46 x 16 is not that much different so I think that would be a good choice. But hell, if you've been riding 52/14 then you probably won't like it.
  23.  
    yea, the calculating thing that got posted earlier said that 45/16 had 16 skid patches and 46/16 had 8, so 45 sounds better

    You guys should check out the rabbit gear calculator. It not only gives you ratios and skid patches and crap, but also gives comparable ratios. For example 46x16 is the same as 43x15 except for the number of skid patches. At least with this tool you can get an idea of where you want to be gear-inches wise. I generally try to run the smallest chainring/cog combo to save weight where I can.

    you cant be serious.. you think that changing your gear ratio is really changing the weight of your ride any little bit ? Your more likely to weigh more from what you ate for lunch that the added grams ot your chainring from a gearing step up..

    coming from bmx, when i switched from a 44-16 to a 30-11 gear ratio, i saved over half pound. and that was with a standard 1/8" chain and 1/4" sprocket.
