can anyone recommend some plain black super roubaix bib tights, without a pad ?

Last pair I got were from Lusso and have done a couple of winters use without any issues. Quite long in the leg which may or may not suit.
I wouldn't touch Lusso with a Mancunian barge pole. I had some 3/4's that the fabric went funny after very little use. 'Lycra leprosy' when all the little elastics start breaking down.
Lusso were 100% useless in their product support even after escalating to the MD.
Initially I was pleasantly surprised by their quality compared to the big brands I normally use (Gore, Assos and Castelli) but they're actually more expensive if they need replacing every couple of years.
I'd just buy Assos and be done with it (and did).
I'd also come here to say lusso. I've a pair that are years old.

Just bought a set of Mavic Cosmic Thermo, have a pad but you could just unstich it.
