Jay's post about wheels and bike weight reminded me of something... (very nice looking machine, there, by the way!)
The listed weight of an Xstream is ~26 pounds (although I have an Xstream26 model, which is spec'd at 30 pounds, it's got "regular" Xstream components -- so, 26) -- but like all bike specs, this is with wheels and tires, but "naked", without pedals and other accessories.
I've never been a "weight weenie", and carry my kickstand proudly (despite John and Randy Schlitter's admonitions -
)... and switched the front brake to disc a few months ago -- and for typical riding, I carry a tool kit, a RoadMorph pump, a Fastback 70 water holder, a bottle cage, and a seatbag that contains two tubes, a spare tire, and minor other things. I use Velocity wheels and Duranos for road riding, but heavier wheels and Marathon Plus 1.75" tires for harsher situations.
So, I put it on the scale over the weekend, with the Velocity/Durano, and was somewhat surprised to see that it weighed 35 pounds -- an extra 9-10 pounds of stuff, basically -- WITHOUT water!!! Meaning that it hits 40+ when I carry water and put on the heavier wheels with the Marathon Plus 1.75" tires.
A bit sobering... No wonder climbing Loving Hill on the White Rock night ride is so tough...
