I own a Trek Multitrack 7000 that I bought in 2005. Now has several thousand miles on it. Originally purchased just to run around town with the with the 2004 Trek Navigator 100 used for trail rides. The lighter 7000 seemed ideal for quick trips around town in traffic.
After I bought it I did have two spokes fail in the rear wheel which the LBS took care of under the warranty. Trek, and others, had some spoke problems due to a batch of steel used to make them. But after the two spoke failures there have been no problems with them.
After I wore out the original Bontrager tires that came on it I switched over to Continental Travel Contact tires. A bit high priced but they made a big improvement in how the bike pedals and handles. I use the 7000 on asphalt streets and trails and "stone dust" trails. An average ride is usually between 40 and 50 miles in a day. Traded out the cushy seat for a road bike type seat. For the price it is tough to beat if I just want a day out on a trail.
