Not sure I fully understand your question
@victor.
I can say however that I have had some great deals from
CRC,
Wiggle, PBK &
Evans.
Both CRC & Wiggle have a 12 months returns policy too which is good.
I have never used Rose or SJS but I have had some hard to find stuff from Bobshop.de in Germany who are very good and another place in (Spain I think) whose name eludes me (I will post back on this).
I do think it is good to support your LBS but 'not at any cost' (if they only ever charge RRP or are rude or won't do small-ish jobs on your bike for instance).
Hope you find what your looking for & in the meantime enjoy your cycling.
Edit - bike24 in Germany (not Spain) was the other I was thinking of.
Also acycycles (France) are competitive & have a large range too.
