Tried this and it wasn't to my liking. 42x16 wasn't enough top end as I ride almost 100% rural. For an urban, heavy traffic, filtering type ride though, it's probably perfect. So, I bought a 46t Rocket Ring...should've got a 48.
They're made to accomodate 110 or 130mm bolt patterns. Went to a local hardware store and got 10 3/8" star washers for under a dollar. This was enough to take up the slack of the double chainring bolts. 2 on each unit. One needs to use some lubricant and channel locks to mount them on the chainring bolt sleeve, but they WILL fit I promise.
Like another poster said, mount your chainring on the inside of your crankset for a staighter chainline. Or one can order a Sugino 103mm bb from www.universalcycles.com
for about 40.00. They've got one for 31.00 and one for 38.00. They only come in 68mm threading, though. They mount w/a Park BB-2 tool.
