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)

Walk upside down?

When walking the back wheel to tighten the chain, is it o.k./helpful to turn the bike upside down? This is obviously a Bad Idea with a geared bike, but horizontal dropouts + no shift levers would seem to make inverting harmless, and make it easier to see and handle the wheel and nuts.

I always do. I don't see why it would be bad?

I was wondering the same thing. I'm picturing stem mounted shift levers. Barring that I can't see anything wrong with it.

I've read some condesending online critisisms of turning the bike upside down to work on it, but that is what I do, especially roadside. Sure one can learn to do some stuff keeping it upright or on its side and some stuff is better to do upright. edit: it was in the r.b. FAQ: http://draco.acs.uci.edu/rbfaq/FAQ/8a.5.html

In my garage I have a carpet I turn bike upside down on.

I'm not so stupid as to turn it over on a computer or other damagable part or on nasty surface.

Be careful with fingers when you have a fixed gear bike upside down.

I developed this fear of spinning rear wheel on fixed gear upside down that is so ingrained I have trouble getting near a rear derailer on an upside down bike.

most modern hydro disk brakes are closed resivoir so unless you're actually pumping the brakes while the bike is upside down, you ain't introducing air into the system. I've been a mech off and on for close to a decade now and have used stands to work on my bikes, the decade before that I just flipped my bike on the saddle to spin the wheels. No problems.

Some deraileurs can't be adjusted correctly upside down. What with the springs and gravity and all.
Easier for chains to come off while shifting upside down as well.
