My wife and i ( 63 and 56 yrs ) are new to biking, a month back I picked up a couple used treks, 7100 (03) for her and a 7500 (04) for myself. The 7100 could not have been ridden more than a few hundred miles. Note : She loves the Twist Grip shifters.
After initial purchase, helmets, clothing, tools and a bike stand i am giving each a complete check out and 'tune up' .
All went well with cleaning and adjusting with one small concern. There is a slight 'clicking' noise coming from both the pulleys on the Sram ESP 3.0 rear derailleur. I have not try to take the pulleys off to clean a lub as i don't want to mess them up and put out of service right now. We are going away with bikes next weekend.
Is that clicking noise normal ??? Are the pulleys serviceable ??? I realize that derailleur is inexpensive so shoul i just replace it ??? fwiw it does shift very well.
I am new to biking and new to the forum so go easy if these a dumb questions.
I am not familiar with the sram rear derailleur but I know that for shimano ones its is as simple as removing one screw per pulley and they just slide out. Once out clean them up apply some lube and screw them back in. Go to http://www.parktool.com/blog/repair-help then just click on the derailleur and it should have some guides as to how to service and troubleshoot for shimano and also sram.
This X.4 model looks like it might have removable pulleys, and should be a direct upgrade to your current one: http://www.amazon.com/gp/product/B001FC9HRO
Another thing to think about is that the clicking might be due to a chain link imperfection, making the noise each time it runs through the close confines of either jockey wheel on the derailleur.
