Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

I'm impressed how fast my FG is...

I assumed having just one gear was going to be a handicap during my morning commuter racing sessions, but I feel as fast if not faster than on my geared bikes...even in stop and go traffic...

I guess not having anything to think about when the light turns green other than hammering the pedals has its advantages...

Yeah, a cleared mind and a better connection with your rear wheel make the fixed gear freeing and fast.

put a bike computer on and measure it, or get a GPS app for your phone and you can get a full analysis. Only hard cold data can reveal the truth.

Same here, I selected a gear ratio the same as the highest gear of my mtn bike which I used to commute with... so much faster on the fixed gear! I know that this is also a comparison between wide knobby mtn bike tires and thinner road tires, but man, I like!
Did the gps test too, and found myself cruising at ~17 mph, peaking at just over 20 (44-17 ratio, for just under 70 GI).

You chose a very sensible gear for the street. I run a similar gear (42 x 16 = 71 gi), which is perfect for my terrain which is rolling moderately hilly and sometimes windy. Many people IMO make the mistake of running too high gearing, which does not permit them to maintain an efficient cadence, and they actually go slower.

You ever considered that it may be due to you are forced to constantly pedal while on the geared bike you have the option to coast if your "legs get tired"? This is why I use a FG for commuting and for training.

i run 44-16 on the street and it's WAY too low for the track. i also have run 44-17 and that was fine but i was spinning like crazy down hills. there be some hills here.

i dunno. i feel like i'm faster on my heavy commuter bike if i'm in a hurry, but faster on my fixed gear if i am trying to not sweat.

Wow, that's kind of high...is it rather flat where you live?
I ride with a somewhat low...44/17, with quite the steep hills.

Can I get opinions on 48/19 on flats? I'm trying to whip skid with it but I just can't do it. Is it my ratio or I just need to more leg power?

Skidding is very easy, when you lean forward. Talking about whip skids here.

Just because you're always pedaling doesn't mean you're putting anything into the pedals. So often are the pedals just carrying my legs when I'm tired.

48x15 is perfect for Tokyo. Cruise at around 30-35 and my computer has registered my fastest sprint up to be 44. I can't maintain over 40 for more than 30 seconds or though at the moment because I haven't been riding as much recently.

Vixtor says good thing. 42-15 = 74gi which is about what 48-17 gearing is.
