Triple crankset --> 39t single ring crankset

Can a triple crankset (52/39/30) be modified to a single 39t crankset for single speed, by removing the 30 and the 53t rings? I haven't been able to find any info that might suggest this as a possibility. Thanks.

im pretty sure you can just get some track chainring bolts (they have to be the right size) for like 7 or 8 bucks and just take the other two off and screw on the 39 with said bolts.

You will need to either buy some short stack bolts or grind down the current ones, but it can be done. The only snag might be that the posts for the inside ring might hit the stays on some frames depending on the chainline you need.

Everyone with a budget road conversion does this, it's fine.
