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)

wow this guy put a 400 wheel on his 200 leader frame... and then had it "professionally painted" (splattered paint all over it)
way to ruin a bike's value


That ugly bike has some UGLY bars.

I have a leader and my hubs cost as much as my frame did. hah. then came the rest of the wheelset. But that is just too much for me

I guess my opinion is biased since my road bike weighs considerably less. I also don't think static weight is that important (eg brakes, derailleurs).

but even the cheap road bike i had for a while with full tiagra or sora I would say is more efficient. sure put in the same ratio the fixed gear feels like it accelerates slightly faster, but I'd argue a road bike is more efficient as it can keep the rider spinning that 90-120 rpm regardless of the speed being traveled. spinning up hills or up to speed from a stop is more efficient than standing and mashing.

The efficiency being referenced is purely mechanical. A straight chainline delivers slightly more of the energy you put into the cranks to the wheel. Certainly if you start and stop and cross varied terrain, changing gears might allow you to put more energy in before becoming tired, and this may greatly overwhelm the slight loss from an un-straight chain line. But that is not, in certain technical senses, more efficient.

So the superior mechanical efficiency of a fixed gear is in most cases not going to be an actual advantage for getting places with less effort. But many find it feels more rewarding. You may or may not find this to be true yourself, but if your fixed gear isn't at least a bit lighter than your road bike, you're not comparing comparable quality bikes in the first place.

Fenders may look fugly but goddamn I wish I had a pair today.

Just got back from a ride and I look like I was riding a MTB through a swamp

You'll appreciate those gears when you're dragging 140 lbs. of groceries behind you in a trailer, trust me on that one.

Ok, I take back my original assertion that fixed gears are efficient. You win, road bikes are more efficient. Who cares.

I've seen research that pegged the actual efficiency gain around 5%. In a few gears, it was close to 7%, but generally less than 4%.

So, not that big of a deal.

Enjoy your fixed, but don't romanticize it too much. It is what it is.

Oh I definitely wasn't trying to suggest that single speed bikes are categorically superior to geared bikes... a fixed vs geared debate is just silly. Ride what you like and what best suits your preferences and needs. For me, its fixed... but then again I take my car to the grocery store.

It's a BoB Ibex, it's rated for 70 lbs. but I have a tendency to "overload" it a bit from time to time.

Actually, I can carry more with the trailer more easily and it's less hassle to get in and out of the apartment than one of those things.
