New 1x10 project advice?

Slightly confused by all this.. why would you bother with 1x10?

Sure you may only use 10 of the gears but if your going to all the hassle of a bashguard/chain retention and your already buying a set or ergo's, why not just run 2x10? At least that way you'll have the option to use them if you need and it'll cost about the same.

Seems bizarre to me.. and a well set up front derailleur will cause you no problems at all.

I was also wondering this. Can understand it for cyclo racing etc. but the weight penalty is minimal for general riding.

to the OP =Is there a particular reason you prefer this setup?
