Okay, so here is how it went down. Near the end of a pretty epic ride (30 miles) I cut off on some techy singletrack that a friend had made a week before. Coming through one of the switchbacks, I heard a noise in the area of my rear hub, and then my bike stopped dead, as suddenly as if a metal pipe had been jammed in my spokes. At first I thought it was just a stick, but then I noticed my rear derailleur. It was in the shape that you can see below (if the pictures work). This was about a 20 minute walk from the end of the ride.
This was all that I could find on the ground.
I have no idea how this happened. I wasn't putting abnormal force into the cranks, there were no sticks in the wheel or derailleur, nothing. So now, I have to go out and get a new derailleur. Unfortunatly, I'm 15, so I cannot exactly spring for a new XTR derailleur to replace my ravaged one.
So, here is my predicament. I cannot get a new XTR, so I was looking at XT or LX. I would love to get a sram X.9, but I just got some rocket trigger shifters, so they wouldn't work together, and I cant get new shifters too. So, is XT really worth it? I can get a new XT for about 60 bucks, or a new LX for about 45. I might be able to get a better deal from my LBS, but probably not. The above prices are from pricepoint. So, should I spring for the XT? My riding buddy thinks I should do it, because it is rare that I damage anything, much less my rear derailleur. Also, there are different versions of the XT and LX. Which should I get? I think that one of each is for rapid rise, so I dont want those. But I dont know which is which.
The names are as follows.
Shimano LX Mega-9 M570 SGS
Shimano LX M580 SGS
Shimano XT Mega-9 M750 SGS
Shimano XT M760 SGS
Which should I get? Please help a confused kid out here.
