If you are used to a road bike, it feels slow. I think it is more perception than reality, judging from my commute times on my LHT versus my Felt Z90. I think more of it has to do with the fat tires and plush ride than the weight. I always take the felt on group rides, but I think the biggest advantage there is the close gearing relative to the LHT, more than the weight. That said, I'm no racer, and marginal speed differences just aren't that important to me. I love my LHT for utility and commuting, and am looking forward to touring on it.
