I rarely use the smaller chainring but I really do not want to turn my bike into a fixie. So I was wondering; can the shimano alfine FC-S500 crankset (https://www.shimano.com/publish/conte...00.-type-.html) be used with 8/9/10 speed regular (tiagra/105/ultegra etc) cassettes? Can I use the CN-HG53 super narrow chain that shimano recommends for the crank set and keep the rear cassette/derailleur setup? I would really like to do this because:

1. like i said, dont have much use for smaller ring,
2. saves me money on front derailleur + shifter!!
3. looks cleaner and simple

with all that said, can this be done or will my chain keep falling off? will the shifting in the rear still be functional?

on a side note, has anyone used this item? how does the quality compare with other multi chainring cranksets shimano has?

That is the crankset that came standard on my Civia Hyland Rohloff, the double chainguard version. I do not see why it would not work with a rear derailleur but have no actual experience with doing so. Been fine so far but I have not heard of problems with any recent Shimano crankset. It is a two piece external cup bottom bracket crank as I presume that you are aware of.

The only consideration in my mind would be whether the chainline will be satisfactory. With the guards on both sides of the chainring, as on mine, I would think that the chain coming off would be very unlikely.
