Well i got the XTR rapid fire shifters and an XTR front derailer. When into bike shop to have them put it on...was lookin at a XT Deloare cassette they wanted $99 for. Come home and found the same one in mag for $58. Ordered a SRAM 990 for $88. Should be here in a week and have them slap it on. Doubt that i will notice much difference but when the bike shop brought out the one I had (HG 50) an the Deloare XT...you actually could feel a difference when you pick them up and then the machining of the two were night and day. What the hay...its only money and is now my hobby...might as well go for it. Hope the SRAM 990 is a good as that XT...by the way a XTR cassette was like $315...couldnt justify that one.
