I'm guessing the rotational weight difference is what you are feeling. Compare the weight of your Atlantis tires and rims, to that of the Surly's. It's likely more, but I don't know your Atlantis wheels. 700g for a 700c Rabbit hole rim 1205-1229g for the Knard 29 x 3" 27 tpi http://fat-bike.com/2012/01/tire-weights-for-fat-bikes/
A 700c Synergy weighs 500g fill-in-your-tire-here :) I'm going to guess off the cuff you're going to have over a pound per wheel more rotational weight. Some will say it does not matter, some say it does. To me, yes, it does, and yet, it does not. For the bottom line is, Do I enjoy riding the bike as I define my Joy of Riding ? And finally, each bike is it's own Bike. the Surly isn't a Rivendell, so comparing the two , unless it pleases you to do so, is an exercise in futility :) An apple is an apple, an orange and orange. Love them both or neither or one , I get to choose !!!!!!! -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
