Yeah I run a chainguard/42/+29 on my Kogswell "scraper" bike from a 130 sugino double with a TA conversion ring. It works very well, even with regular old pants. There are 42t rings that will bring you from a shimano 130 (Alize/K) or even a campy 135 down to a 74 (Vento/K). But why bother when you can get a packaged double that already does this without the chainguard? Especially as the fellow was concerned with weight. Probably most of us would say unnecessarily concerned, but you want what you want. (The lightest way would be ditching the square spindle BB altogether and go with a splined connection, heaven forbid!) The White Industries variable slot is interesting too. I considered them when I was building the Saluki. I'd forgotten about that. The slots system seems sketchy at first look but would appear to work well for any BCD inner. They certainly offer a wide range. Anyone use them? http://whiteind.com/cranks/roadcranks.html
