Does anybody proof things at Specialized? They put out a "stop riding" safety notice with a note that they'll update things in a week, but fail to put a date on the notice.

I think it depends on the Sirrus model but my X comes stock with 38s and depending on the tire and how muddy the terrain is, I think you could probably run 42s.

I bet your crank is 110 BCD which limits you to 38t as the smallest chainring you can run. To go smaller, you have to go to a MTB crank.
