Hey nuke, FYI 1 tooth on your chain ring, from 42 to 43 is not going to do much of a diff in gear inches ya know. If all you care about is skid patches then cool, get the 43.

I have an '07 Redline 925 and it's great. I have the 42_15, I like to run 44_15 for a little taller gearing and went with 42_14 for just riding flats.

I got a Sugino messenger crank with 1/8" ring and went to 1/8" cog, a surly or dura ace. Got velocities, a fixed/ fixed rear and gatorskins, carbon fork, riser bar, sanded the 14 tmies it said Redline on the frame off and painted it. yada yada. It is super smooth. Way better than any conversion I have built, except for the Pinarello, yummm.
