XT v-brakes squeal like stuck pigs. I read the reviews before I bought them, but bought them anyway. I tried everything to stop the noise myself, then started going to shops. Most tried the same things, or laughed at me.

Avid SD7s are on my bike now. They are quiet, poweful and lighter than XT v-brakes.

The XTR rear der is a wonderful thing. Look for one on eBay and save a ton.

XT shifters are nice, but LX shifters are a much better bargain. the XTs are only 8g lighter, but cost 40% more. Save money hear and go with an XTR rear.

Price Point, Supergo, Performance, Colorado Cyclist and Cambria have all given me excellent service mail order via 'phone or web, but if you're eBay savvy you can knock 30-50% off the mail order price.
