Weighed it on a freshly calibrated medical scale, so I'm pretty sure it's accurate. It's heavier than husband's or roommate's bikes (both ~$250 hybrids.) It's a 2007, and the day I got it the guy at the bike shop was amused but encouraging and showed me his old bike he commutes on (heavy steel) in sympathy. It looks more like a cruiser than a road or mountain bike. I adore it, just heavy.

Checked to be sure. Tires are 700 x 35. I don't have any issues stopping on my current bike. I have never biked in rain, is that a concern? it does regularly rain, and increasing the frequency of biking will likely put me riding in the rain a couple times a month. I'm not experienced enough to know how to check for a 28 x 34? I can handle the grade...but not for the length of the climb, if that makes sense. I do have a hard time standing to really work the pedals on my current bike....I end up being so slow that I can't keep it steady enough to feel safe in the heavy traffic. I won't ride on sidewalks, so I end up walking it up the last third of the hill on the sidewalk. I noticed on the rented mountain bikes, on my roommate's bike, and on the test rides; standing is as comfortable as sitting and I feel more balanced. The body position is completly different....the 7100 is a very upright sitting position while everything I'm trying out puts me far more forward, which I hope helps the climb.
