I replaced some parts: new deore derailleur, unfortunately xt didn’t survive the beating anymore. And while I was working on the bike, I installed Ochain chainring, I’m curious to see if it really makes a difference, especially on long descends.
Rode the bike and then serviced it: Proper cleaning and checking the bearings, also adjusted the head angle from slack to less slack, 63,8 to 64something.
Someone already mentioned 45NRTH. I've Wölvhammers and Ragnaröks. Depends how you define winter, what is good and what not. In Finland I used Wölvhammers regularly (not only cycling but also skiing) but after moving to Austria I haven't worn them in years. Ragnaröks are more than enough here...
