Hi

I have a Hybrid citybike 28" with a electric hub motor on the rear wheel. My componenets are starting to wear out and would like to replace them all with fresh new ones (Rear derailleur/Cassette/Chain and Crankset).

I think the current setup 3x8 (Shimano Alivio) is overkill for my commuting ride and will be more than fine with 1x10/11 or 12 setup (Looks also much cleaner on the bike :-) )

What are my options? I'm looking on Road components Tiagra and 105/MTB components SLX and Deore. Please advise me what to choose.
