snapI don't lnow specifically about the Troika, but DHB are Wiggles own in house brand and have a decent rep for their shoes.
From what I can see the XC1 is 2 bolt MTB/touring SPDs, whereas the Troika is 3 bolt SPD-SL, so it is going to come down to what ledal system you use.
The Troika is available as a road or MTB variant.
