Yes, I raced on a new Wolf Tooth 38T on Saturday, with 11-28 in the back. No problem with chain clearance either.

I think Wolftooth does a 130bcd 38t.Adam

40 is the smallest size they make for 130 BCD: http://raceface.com/components/rings/rings/cx-nw-ring/
An alternative is to use a larger cassette if your derailleur can handle it.

Thanks for bringing it up, Eric. I wasn't aware you could go 38 on 130
BCD... good to know! I could think of a few races where it would be nice
to have something lower than 40-28...

Thanks, Dolan. I meant to add that I'm (mostly ) brand-agnostic on this. For example, apparently Wolf Tooth makes one.

Unfortunately to go to a 38, you'll have to use a 110 BCD (compact) crank.

40 is the smallest size they make for 130 BCD: http://raceface.com/components/rings/rings/cx-nw-ring/

An alternative is to use a larger cassette if your derailleur can handle it.
