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)

ques about chain ring/cogs

assuming all parts are brand new, which will wear out faster: EAI steel cog paired up with a sugino75 track chain ring + izumi v chain??

Chain always goes first.

Depending on your gear ratio, the chainring only rotates once for two or three rotations of the cog, so it will wear much more slowly. The chain will wear our first and if you continue to monitor chain "stretch" and replace the chain when 12 links measure past 12 1/16" your will get a lot of miles out of your other drivetrain components.

Its worth investing in quality drive train components if you are diligent about chain replacement. However, I wouldn't bother with the Izumi V chain. It'll wear basically just as fast or faster than a cheaper chain and won't run significantly more smoothly. So why pay 10 times as much for it?

with geared bikes it's the cogs in the rear cluster (smallest first), but it all depends on the maintenance level you keep the bike.
since there is no shifting in SS, both the cog and chainring can last a very long time. you should blow thru several chains before the cogs & chainwheel. (assuming perfect chainline)
also gear ratio counts as mentioned ^^

you have to actually ride your bike for the drivetrain to wear out
