Have had the privilege to ride XTR hubs last year. Was on DT Swiss 350's prior and I can't believe how much less rolling resistance there is in the XTR's. Through flowy sections of trail I am carrying more speed and having to pedal much less. It was not something I was expecting from the new XTR group but probably one of my most favorite improvements.
Thank you for this! Keeping it light and stress free isn't always easy - I think I struggled a lot last year to stay motivated, rode a lot of the same trail but did it to be out in the woods and in the trees. The trail is usually pretty well ridden by families or people newer to the sport and most of the more experienced riders stay away for that reason(people in their way as they try and get the top strava time). Frankly people new to the sport have an amazing outlook and their vibe is infectious. It got me through the season, brought me back to feeling what I used to when I started. Keep it light keep it fun!
