Problems with shifting

Hey I have a new trek 1500 with about 100 miles on it. I know you wont get as clean a shifting on a triple like mine as opposed to a double, but when I need to get into my grannie gears when climbing, the chain either starts making horrible noises or starts to jump off the chainring. Anything I can do or time to take it to a pro?

Check this site out - it will walk you through adjustments and you really don;t need special tools for this.

Most bikes from shops are not adjusted thoroughly and that is why they have free adjustments for the first 30 days.

Having worked for numerous shops over more than 20 years as a mechanic and service manager I can tell you that most bikes from shops are adjusted well, and the 30 (or more) day period is due to the fact that cables stretch, bearings break in and various other parts are subject to change from vibration and customer changes. The only exception I would make is that bearing adjustments are often too tight.

The Bianchi I bought last fall was far from properly set up and adjusted and I spent some time with the RD as well as other items that were rattling or rubbing. It was a previous year's model so it may have been on the floor for a while, but they made no attempt to check it before I took it home. My test ride was in a noisy parking lot which masked several sounds I might have noticed otherwise. It was easier for me to see to it than take it back, but it left me with a bad feeling about that shop. Since there are lots of bike shops around here, I don't plan to see them again.

My guess would be you simply need an adjustment, which is normal for a new bike after a while. If you bought it at a local bike shop, I would urge you to bring it to them. They should adjust it for free.

Barring that, follow the derailleur adjustment steps that are available on line at sheldonbrown.com or parktools.com
