When you buy a new bike all the LBS give you lifetime guarantees. They say come in for a tune up. I think it's pretty easy to take slack out of the cables and make a few adjustments that they make. The reason I'm asking this is because the first bike I bought had a lot off chain slip. I played around with it myself and got it fixed. Besides that dropping the bike off and being without it for a day or more. I bought a book ( Bicycle Maintenance & Repair by Todd Downs) and I have most of the tools so I was thinking about doing it myself. I thought it would be good to know if something happened on the road or on vacation.Anyhow do you take your bike back for the 30 day or 100 mile checkup or do your own. Thanks George
