I had some bike modifications in mind and was enlightened in the General forum(http://forums.mtbr.com/general-discussion/going-1-2-way-singlespeed-438314.html#post4736082) that I was talking about 1x9 setup.
I have 3x9 MTB wich i plan to use mainly for road and light trail. It is fully rigid bike, and drivetrain and FD is worn, so I want cheaply convert the bike to 1x9. I have new 11-32 cassette and 9 speed chain ready, the only thing i need is a chainring ( I plan to use 44T or similar)
this morning I made a quick test to see how 1x9 setup can be done. I left FD in place (it works as a chainguard), and placed big 44T ring in the middle position on the crankset. Some issues to resolve with this -
(1) i had to file off some steel from the old worn 44Tchainring, as it wouldn't fit to the middle ring place
(2) i had to install 44T chainring in different direction (its inner side to outside), because it has some indentations and wouldn't sit properly
(3) i had to remove pin from the 44T chainring (it rubed agains FD)
(4) i had to place former middle ring in outmost position on the crankset, otherwise bolts wouldn't hold
It looks a bit strange, but works. Since the chainring is worn and is used in opposite direction, there is some crunching noise, but chain is pretty much straight when it sits on the middle cog, and FD rub is also minimal when chain is on the biggest or smallest cog.
I'll call some LBS tomorrow, but may be somebody can help now - since I plan to use 9 speed cassette and chain, I need 9 speed chainring (44T or close) - SS chainring probably won't do. Is there such a chainring without all the ramps and pin and such? And ready to be used without filing metal off? BTW, my cranckset is Shimano FC-M510
