Phil Davies' men will be aiming to return to winning ways after home defeat to Munster.
And front row Dacey - who scored his third try in four games last week - is relishing the size of the overseas challenge as Blues aim to avoid a repeat of the 26-17 loss they suffered on Italian soil back in March.
"It is a tough place to go," he said. "We played out there last year and had a fairly young team, but they really showed us that they are a tough team to beat at home.
"It's a good test before we face Glasgow in the European double header and going into Christmas then with the derby games. Hopefully we can get back on track with a win and carry it through.
"The Munster game was difficult," he added. "They are a strong team, are top of the league and are not to be messed with.
"Obviously they put 21 points on us first half, which is not a positive, but we tried to re-group and we came out seven all in the second half.
"That is a big positive for a young group, but we can't keep saying: 'we're young, we're young'. We need to take the positives out, analyse the game and see where we can improve, especially going away to Treviso."
