I just order the tubes from Kent Bicycle. They are only $3.00 a piece. And Nashbar had the Michelin Dynamic Road Tire 700 x 23 or 25 on sale so I got a set of them for $8.99 a piece. So when the Knada tires ware out I'll have a set to replace them.

As far as weight goes. This bike is 26.5 lbs. The 32 lbs is the bike boxed ready to ship.

The chain is a good chain. Not the best but it works well.

The bike fits a 5' 8' to 6' 2" person quite well. If your shorter then that then look at the 20" red frame.

The bike has two eye lets on the rear for rack and fenders and one on the front for fenders.
