I went into my LBS and had him install a LX crankset and bottom bracket, I did not want the Truvativ crankset back in, I had already had the bottom bracket disintegrate at 60 miles and at 166 miles as well as the drive side crank come loose on the axle. I also confirmed by phone with Sram customer service the problems they had had with the GXP bottom brackets for 2006 and I was told that they felt that those problems had been worked out. Their rep on the phone told me that typically they will send out a replacement crankset to an LBS without requiring the defective one be sent to them first, reducing the delivery time to typically three or four days for the LBS to receive the replacement. They sent me, through my LBS, a "repaired" crankset and bottom bracket (which had a new plastic sleeve and bearings on it). This crankset had more wear on it than mine would have had in three hundred miles of my sixty year old ass riding the bike. It was unacceptable and I am now awaiting a new crankset and bottom bracket as soon as available, Sram said they sent the first set as a "fix" job so that I would have use of the bike while I waited for the new components. While I appreciate the jesture, I live 70 miles from the LBS and have made three trips to see them since I bought this bike with this crankset and am not interested in wasting more gas or time on an inferior product. My plan is to install the crankset and bottom bracket on my flat bar road bike when I do get them, where they won't be subjected to quite as hard of service. I do believe the Shimano LX is much smoother and efficient than the model Truvativ crankset I have but I do however love the Sram drive trains and have ordered a new XO rear derailluer and XO shifters to go along with my new 990 cassette. I have X7 derailluers and shifters on my road bike with a 970 cassette and I feel that the crankset with the GXP bottom bracket will be an upgrade. I do agree with you on one thing, and that is the incompetence that I've seen displayed by my LBS or soon to be, ex-LBS. New Orleans is now reopened and I plan to shift my business back to a local dealer, even though he doesn't handle Jamis, he has a great service department and customer service reputation.
